Title: 2005 Tiger 955i stepper motor help
Post by: nigeh on July 22, 2014, 07:22:49 PM
Hi all

Was advised to visit here as it was suggested there is more help/knowledge on here than other forums!

I have finally used the Tuneecu software this evening on my Tiger as been having issues with an erratic tickover and very lumpy. low-down, acceleration.

I have searched for some info but not come across the right onfo, or have missed it! I am after help with info on the 'stepper motor' as think that is my issue! I have replaced mine as felt sure it was faulty, purchased a brand new one!

Anyway I am sure that it needs to be set correctly when fitting a new one but there is very little about how to actually do this everyone just keeps referring to a TPS reset!! Based on how the stepper works I would have thought it important to set the 'plunger' to the correct height against the three holes in the body of the motor so that when it adjusts the height of the 'pluger' it covers the holes the correct amount. Is there a method for doing this or do I have to wind the 'plunger' up or down on the thread and keep turning ignition on/off until I see it cover the holes correctly?

Any advice gratefully received.

Also does anyone have the actual values you should see on the 'diagnostic' screen when the bike is at tick over as I have no idea if the readings I am seeing are correct or if they are indicating other issues, ie injection pulse values, ignition coil readings, throttle and O2 readings?

I have looked through the 'workshop' manual but they seem to just keep referring to how to use the triumph diagnostic tool so there are no values.

Cheers, TTFN

I should have said bike is running the Off road Triumph can and the TOR tune with a K&N air filter (NO airbox mod)

I noticed this evening, when I saved the current map, that the map number is 10177 does anyone know if this is the Triumph tune as had it done at a Triumph dealer?  My research shows I should be using the 10173 map! 

I will load that one on and also mess about with the IACV settings to see if I can get it to idle a bit better!

Paging Bixxer Bob to the white courtesy phone!

Nige the accepted gurus for the ECU are Bixxer Bob and Metal Guru, a pm to either might get you an answer, however you are asking rather close to some of us going to Scotland for the 2014 meet.

Was it me I would have said the stepper motor would have been factory set but hey I'm no expert

Tiger VIN#206547 and up use the 10173 tune (TOR and Aftermarket exhaust). 10177 is earmarked for Brazil only and remember that using this tune in a non-Brazil ECU is troublesome per others.

Best to replace the corrugated hose (if they are still OEM) with silicon and re-balance the throttle-bodies is highly advised. The OEM hoses crack and split causing vacuum issues (of which the "stepper motor" cannot overcome to trim out).

Thanks John, Stitch

I have looked at several, excellent posts from both Bixxer Bob and Metal Guru and guessed they were the ones who know how to sort the 'black magic' that is an ECU!

Stitch that is very interesting your comments about the tune, my VIN is 226*** so well after the start range for the 10173 tune.  I shall be calling the stealer later to discuss with them as this was done a couple of years ago now.  I only let the Triumph dealers in England look at the bike as bought it there so expected them to know what they are doing......I know, I know but when you don't understand how it all works you have to trust someone!!

I have looked at the corrugated hoses, checked them when I replaced the stepper motor, and they seem in good condition, no splits and I removed the 'T' piece that had the scotoiler attached to it and re-connected the vacuum hose together with in-line connector.  I did think of changing the tubes but thought that silicon ones could implode and close up so decided to stick with the originals.

I balanced the throttle bodies a couple of weeks ago when this all started in case they were causing the problems.

I am going to load on 10173 Map see how that goes then, if needed, will tweak the stepper motor so fingers crossed but does ayone have the values I should be seeing on the diagnostic screen on Tune ECU as in my original post as it would be great to compare values with one running correctly otherwise I am 'flying blind'!!

Thanks again for input and enjoy the meet but watch out for the midges!!!!!

Before you do the stepper motor blow in 10173.  Reset the trims at the same time. 

Set the stepper motor to 28 steps

If you're sure the TBs are balanced,  do an adaptation (look in the how-to)  the criteria to be met for an adaptation are in there.

Then, the stepper motor setting should be between 20 and 35 steps.  Set it midway then, with the engine warm, blip the throttle, aim for it to pick up cleanly and settle back to tickover without dipping below or stalling, or popping too much (a little popping is normal).  Try a couple of steps at a time, up or down, you'll soon get a feel for whether you're going in the right direction.  If it doesn't seemto make any difference, leave it at the mid setting and ride it.  If the setting is too low, it will die on you when you pull up at junctions etc.

Many thanks for that Bixxer Bob

Looking on the Tune ECU site there are several 10173 maps!  Should I just go for the standard 10173 one or the AFMOD2 or TUNEAF?

I also meant to say that I have just ordered an O2 eliminator, due any day soon if the donkey gets it here!!

If the device does not arrive by the weekend will I still be able to do all you say and THEN fit the eliminator, as plan to attack the bike again on saturday!  If I have to do all you suggest again I will wait until it arrives!

Cheers

Nige try the search button it helps enormously. Metal guru has on one of his posts a screen shot of a custom map he did with some values shown.
A quick search under ECU MAP came up with this thread with a screen shot on page 2

Thanks John

I took a look at the values and they are similar ish to mine but will change with different temps, etc but a good gauge, cheers.

Another thing I have not mentioned is bike has done 42,000 miles and has NEVER had the shims looked at!!!  TBH I couldn't be bothered to strip it down that far when each time I have looked at forums people have posted they checked theirs at 12k, 24k, 36k etc and have never needed swapping out so never bothered!  I do have the shim tool so if this tune/tweeks do not sort it out I guess that is the next thing to check.

Just run the standard 10173 map.  MG and I run our own maps from time to time, but - for instance - my bike doesn't like MG's map.  They're all different so - unless you really know what you are doing - stick to standard.  I've been running a stock 10173 for 3k miles with no probs.
Title: Re: 2005 Tiger 955i stepper motor help
Post by: nigeh on July 30, 2014, 01:46:42 PM
Cheers BB

Have loaded 10173 on and adjusted stepper to 28 but tickover was too high so have gradually reduced stepper back down to 10!

Problem is that when I 'blip' the throttle when the tickover is around 1500/1600 rpm (stepper around 28) the motor spins up with no stuttering but as soon as I lower the stepper to 10 (tickover around 1200rpm) and 'blip' the throttle the engine splutters and is not a 'clean' blip!!  Hope that makes sense!

The one thing I have not done yet is ride it and rag the nuts of it so will do that next!  :icon_mrgreen:

You should be able to achieve steps 20, so yes, ride it - at least 30 miles.  What is your long term fuel trim?  Should be about 4.18.
Title: Re: 2005 Tiger 955i stepper motor help
Post by: nigeh on July 31, 2014, 01:12:28 PM
I will take her for a spin next day or so if I get the chance.  LTFT is 4.0%

Will post back up when run her for 30 miles or so.

Cheers again for your help.

Post by: Bixxer Bob on July 31, 2014, 07:58:50 PM
You could try bumping it up a bit, nearer to 4.18 and see how it goes.  With more fuel in you should be able to bring up the steps to where they should be.

Post by: nigeh on August 09, 2014, 04:48:57 PM
Finally got to ride bike today for 30 miles, even treated it to SP98 petrol!

So I upped the FTFT to 4.2 and set the stepper to 25.  I ran bike up to temp first and blipped her a few times and with each blip I watched the stepper reading drop down from 25 and it settled at 17! 

Went for a ride and tickover was up at 2100 rpm.  Bike did seem to run OK-ish all be it when I first started it up it was spluttering a fair bit but that soon cleared.  In 'simulated' town riding i.e low speed riding in 2nd/3rd gear the spluttering and snatching has gone but it is still not right!

Tried some 'hard' acceleration in 2nd and 3rd from around 3000 rpm and pulled cleanly but then tried some 5th/6th gear acceleration from around 45 mph and it stuttered a bit before pulling away.

When I got back I connected laptop up again and noticed that the stepper had set itself to 7!

As I fitted a new stepper is there a procedure I should have done, when fitting it, to set it to the correct level or should the ECU sort this out, obviously it isn't or it would not keep changing.  Each time the engine temp was around 100 give or take a little and whilst I appreciate it will change to adjust the air flow it seems to be all over the place and never stays at the same setting for a set engine temp!

I also noticed, in the diagnostic screen of TuneECU, that when I blipped the throttle the TPS reading sometimes did not move and when it did it only jumped up to a very low reading, say 16 then dropped back but next time I blipped the bike the TPS dial did not move!!!  Would that indicate a faulty sensor?  I have had trouble with this three years ago but then it was just the connection and the symptoms were that at around 85 mph ish the bike kept cutting in and out, not great in the outside lane of the motorway!!  Eventually it got so bad that the Engine light came on which was great as at least it showed it to be a fault in the TPS that Triumph tracked to the connection on the sensor.

Anyway any further input would be gratefully received as getting bit hacked off with it now and looks like I am going to have to check those shims that I do not really want to do until I have got all the other settings correct! :icon_mrgreen:

And you are sure there isn't a vacuum leak? Having the IACV (Stepper motor) trim to 0 is usually a tel-tale sign of a vacuum leak. Silicon hose to replace the corrugated lines is a inexpensive thing to do in your situation (including the line back to the ECM where the MAP sensor is).

Post by: nigeh on August 10, 2014, 08:22:03 AM
Hi Stitch

I did make sure I checked all the convoluted pipes from the stepper to the inlets and the one back to the ECM and I could not see anything and I had them all off to check but I will, as you suggest, change the pipes as they are 9 years old now so for the sake of it I will give it a go.  Can't buy anything today as France pretty much 'sleeps' all day Sunday  :icon_mrgreen:

Will report back soon

Cheers

Did the tickover drop to normal as the stepper trimmed down?
Title: Re: 2005 Tiger 955i stepper motor help
Post by: nigeh on August 11, 2014, 04:51:14 PM
It did drop down but at 17 it was still too high and after the ride when it had dropped to 7 it was still a little high and when I blipped it it went back up to around 1700 rpm

I am in the middle of messing with it now but getting a bit  :BangHead with it!!
Title: Re: 2005 Tiger 955i stepper motor help
Post by: nigeh on August 13, 2014, 09:50:29 AM
No matter what I change the settings to I still have an erratic tick-over and a 'spluttering' when blipping the throttle!

On reading even more posts on t'interweb I read that the inlet manifold gaskets can be an issue so while ticking over I sprayed brake cleaner around the gasket and each time the tick-over increased so I now have the inlet manifold off and although there are no obvious signs the gasket is not in the best condition so will have to get a new one of those.

I also read that there is an 'o' ring behind the TPS but looking at the micro-fiche on the triumph parts site there is no mention of one! Perhaps there is on a daytona 955i?? 

I was considering putting a new TPS on but it seems to be OK.  The voltage on the TPS at tickover is 0.55v and when engine is revved I saw it go up to 1.4v ish so that seems to be working.

Still the saga continues!

Post by: Bixxer Bob on August 13, 2014, 10:05:02 AM
Yup, the gaskets do leak, AESDJ had his go recently.  Part of the problem is the chocolate torx screws that Triumph used.  Replace them with good quality stainless steel hex socket (allen) screws.  Be careful not to round the torx heads as you remove them because, as I said, they're soft.  I did a "how to" on the subject:

http://www.tigertriple.com/forum/index.php?PHPSESSID=rmd6cipopsa9g84quar9n0qdc5;topic=6777.msg44959#msg44959

If you can read the throttle position in TuneECU with the engine off but ign on then TPS is working BUT if it had a scratchy track in the internal pot then you'll only see that using an oscilloscope, that's how I found mine. 

Fix the gasket and balance the TBs first though, there's a good chance that's where the problem lies.
Title: Re: 2005 Tiger 955i stepper motor help
Post by: nigeh on August 13, 2014, 11:25:38 AM

I will get some replacement bolts and make sure I use those.

Last time I even looked at an Oscilloscope was just before the old King died, whilst I was at school!!!!  That sort of device is far too techie for me!  :icon_mrgreen:

Only pain here is the nearest Triumph stealer is an hour away but still quicker than ordering one from England, as I normally do, but in a rush this time as while I am still in the mood to try and fix it rather than torch it I will keep plodding on!!

Will report back soon.

Going to be a slight delay as our French cousins don't have the gasket in stock BUT they can get it for next Wednesday!!

Even with the paper gasket, I still used gasket goo.  With modern goo I'm not sure you actually need the paper bit?

Post by: nigeh on August 14, 2014, 09:58:47 AM
I was thinking that too BB!

A good layer of gasket sealant should work but I will wait for the paper gasket to arrive and then use both as you suggest.

I may go on the hunt and see if I can find some, if it exists, gasket paper so I can cut my own out!

Post by: Sin_Tiger on August 14, 2014, 12:09:41 PM
You used to be able to buy small sheets in motor factors but I haven't seen any in a long time, I guess the demand isn't there anymore.

I've regularly used navigation charts as thinner gasket but you probably don't have access to that. Any thick paper or thin card will do, even thick flyers or old calendars will do it. Box it against the joint, is you lightly grease the joint first it helps to hold it in place and makes the markings easier to see. Then rub the edge of a spanner around the edge and over the holes, put a couple of bolts or screws in to aid location. Don't be tempted to tap as you can damage the edge, especially with alloy. Then remove it and cut around the markings.

Forgive me if this is teaching you to sup soup but it might help someone else.

In fact I could do it first to see if it was the gasket then swap it for the proper one when it arrives!

While you have the inlet manifold off replace the TPS as a matter of course. It will be worn out at that miles.
There was a Scottoiler fitted and reading the text the joint was re-made, to be honest for the price of 5mm silicon vacuum tube just replace the convoluted tubes, I'll bet there is a leak there somewhere, as they loosen their grip on the inlet stubs.
Get it all set to std settings for now and see where it is running badly. Don't forget that after each download the TPS will need resetting and adaptation procedure carried out. Make sure Throttle Bodies are balanced EXACTLY as very important. Be aware, there are 4 stubs on the IACV and one is blanked off, make sure connections are correct. Remapping should only be carried out when ALL service adjustments are within tolerance or you will waste days trying to get it to run correctly. Also unless you write down every adjustment you make it is impossible to remember what has been done so carry out one at a time. While the tank is off, check the shims, and remove the Airbox baffle. Drill another inlet hole opposite the Snorkel on the Airbox the same size, all helps by small amounts to refined running.

That should keep you going for a couple of hours.

Load the Triumph off road map and not the A/F map. Report back any running issues ie surging and can show fix, although the slight differences you looked at on my map make very big changes on the bike so tread carefully.

Thanks metalguru

Was thinking of changing the TPS but have not ordered one, yet!

I have changed all the vacuum pipes from the IACV to manifold and the one from air box to ECU.

I have done the TPS reset a few times all be it I am not sure if it actually works even though the message 'TPS done' appears on the TuneECU screen!

I will look at the shims this weekend and will 'hack' the airbox around too!

Will come back when I have managed to do all these things because as you say it should keep me out of trouble for a couple of hours!!!!  :icon_mrgreen:

After the TPS test done appears the engine must be run until the TPS beacon glows green on TuneEcu.

BTW be careful when opening up the airbox for the second snorkel as the airbox temp sensor is mounted there.

Post by: nigeh on August 18, 2014, 03:59:46 PM
Thanks for that MG!  I just read up about it on the Tuneecu spiel too so will be doing that when bike is back together.

While waiting for this inlet gasket to arrive, decided to wait for the real thing rather than make my own!, I did pull the rocker cover and check the shims, finally!

As far as I can see I am not going to be changing any of them as they are as follows:

Exhaust - 0.19, 0.21, 0.19, 0.21, 0.17, 0.17

Inlet - 0.16, 0.14, 0.14, 0.12, 0.18, 0.15

I have a few over the limit but not going to change them out yet as sure there is another 25,000 miles before I next need to check them, bike has done 42,000 miles now and that is the first time they have been checked!

I was going to order a new TPS but mine seems fine, showing 0.55v, and feels very smooth when you rotate it so will leave it just now.  I thought I had read somewhere that you can adjust them but no obvious way to do it as the housing has no rotational movement where the bolts go through it!  I was going to get it to 0.59v but will just leave as is for now as parts bill is rising and don't want to throw too much at it as bike is 9 years old now, the longest I have ever owned a bike in 33 years of motorcycling and it may be moved on if all this work does not fix it!!

Now just going to clean up all the bits I rarely get to see on the bike while waiting for gasket, saves twiddling thumbs, or cutting the hedge!!!

Post by: metalguru on August 19, 2014, 06:35:12 PM
Your choice as it's your bike, BUT, somewhere on one of BixxerBobs writings he suspected a TPS and although the voltage was in tolerance, when it was connected to an oscilloscope definite spikes were found with the track inside. Ok they are about £70 so a bit dear. At that miles the track will be worn especially at the 0-1/4 throttle position and can be ONE of the causes of your problems as a TPS reset has not cured the problem with the high idle.
Good time to change the inlet manifold soft cheese screws to stainless too.

Just saying as we have been there before!!
Title: Re: 2005 Tiger 955i stepper motor help
Post by: nigeh on August 19, 2014, 08:21:06 PM
Cheers metalguru

To be honest I was hoping it would be fixed after the new stepper, inlet gasket, shim check, etc, etc so I put it back together this afternoon as gasket arrived and took a test ride this evening and............ it is exactly the same as before!!!!!!  On one hand I was being impatient and just wanted to put it all back together but I did think of ordering a new TPS!

I am now ordering a new TPS tonight and thanks to the crap positioning of the TPS by Triumph I am going to have to strip it all down again  :BangHead

I did change the inlet manifold bolts for stainless 'allen head' ones as BB suggested in a earlier post and the original ones did look a bit flimsy!

I do agree that as the TPS spends most of its time at zero to quarter throttle then it will, as you say, be worn.  I did read that post from BixxerBob re using an oscilloscope.

Interestingly the tickover is down to around 1200 rpm and the stepper has set itself to -7

Will let you know what changes when the TPS arrives.

Cheers  :thumbsup

Post by: Bixxer Bob on August 20, 2014, 08:13:13 PM
Just be careful you are reading the shim situation correctly, they are the opposite to tappets.  A shim gap will get smaller and quieter with age until the valve has no clearance at all due to the valve wearing into the cylinder head.  Whereas tappet gaps used to get bigger and more noisey with age.  For shims noisey is good.

Just to refresh my memory, the tickover is now about right but it hesitates on high gear roll on at low revs?  Does it pull cleanly if you're really going for it higher up the revs?   Reason I ask is if it's bogging at low revs when you open the throttle it's not seeing the correct drop in pressure in the airbox that will tell the ECU that the engine is under 100% load and so is not using the correct part of the fuel map.  Before spending any more money (you can always get your money back on the TPS if it's on it's way) Make sure that the box is properly sealed downstream of the air filter, and that the filter is in the right way.  This is a new theory of mine which you may well be able to prove, so you are looking at elbow grommet, oil pipe clip, and tube from airbox to ECU, IACV gasket, throttle body rubbers.  I found, due to some distortion in the airbox, the IACV gasket didn't seal properly on mine and needed a little help care of some 3mm soft rubber sheet.  I found out by using a light shone around the IACV and looking into the airbox with the filter removed.

Post by: nigeh on August 21, 2014, 05:11:28 PM
I am positive I have the correct readings for the shims, and they were double checked by a friend who is well used to doing this sort of work on bikes so the gaps I have are excellent based on age/mileage of the bike.

Bike hesitates at low revs in low/high gears in fact when bike is ticking over it has a rough (almost running on two) tickover but when blipped hard it clears and revs fine.  If you rev the bike up 'gently' it does not hesitate!  When it is higher up the revs, going for it as you say, it pulls cleanly with no hesitation.

I have a K&N air filter and am sure it will only go in one way round but will check! I will check all the seals etc on the airbox using your method of light shining and see what happens.

As of this minute I have not actually ordered the TPS as waiting for someone to come back to me with a price so will do this before I commit.

Will report back

Cheers

I wasn't suggesting you were wrong about the shims, just making sure you had the correct understanding of why the gaps close up instead of getting bigger as we old farts are used to.  Some folks think an upper limit gap needs a thicker shim when in fact it's fine, it's the lower limit shims that folks think are ok but really need thinner shims that are the worry.  Folks leave them alone thinking the gap will get bigger and then are gobsmacked when it closes completely and burns a valve.

Thankfully I am more 'old school' too and decided that a larger gap is good and did not plan on putting even a slightly larger shim in to reduce the gap.

To be honest I was surprised that the gaps were so good considering mileage and the fact that other members seem to have had to replace shims at low mileages!

Going to shine a torch at the airbox later today!!

So finally the new TPS arrived today so I set about putting it on.  First thing was that I had ordered a new plate/bolts as noticed that one of the old bolts was slightly bent.  So who was it that said the Triumph ones a shite? Because whoever it was was correct.  For a start the Torx head was at least a size smaller than the originals don't know whose genius idea that was at Triumph HQ but well done whoever they were  :BangHead

So put the old bent ones back in and put it back together and fired up.  It ran so/so but I have not connected up TuneECU yet but it still has a slight splutter when blipping the throttle but it may be improved, to be honest I am loosing the will to live with it tonight so have stopped or I will hit it with something I will regret!

So tomorrow I will put it back together properly and take it for a test ride and if it is still playing up then that is me pretty much done as run out of ideas/patience although need to get re-inspired as going to Germany in less than two weeks and need to use the bike and I don't really want to ride it like it is but will if I can't sort it properly.

Will come back tomorrow after test ride and report findings

Firstly before doing anything else is to connect to tuneecu.
Maybe teaching to suck eggs here, but,
Connect bike to battery charger as ecu likes volts.
Connect laptop to mains supply to ensure battery voltage is good as maybe some time.
Connect lead to bike and switch on main switch but DO NOT start.
If headlamp switch is fitted, turn off lamps or remove fuse for same.
Wait for TuneEcu to connect.
Download map preferred and correct for bike and vin number, also for off road or not. Remove any remaining faults.
When finished - select disconnect from the menu. This is important you do this before turning off the
ignition as it "closes" the program mode on the ECU.
After TuneECU has disconnected - Turn off the ignition.
Put fuse back in.
Wait 10 - 15 seconds and turn on ignition.
Reset TPS by double click on icon. This will tell ecu throttle is at zero position.
Start engine BUT DON'T TOUCH THROTTLE, let it run for adaptation to occur  at about 90C and green indicator will show.
TPS voltage will change from 0.0 at reset to about 2.2 at idle.
Sometimes this can take a few attempts.

Then with all done it's time to play with the trims.
BTW the stepper is usually adjusted to give a minus number (double click on arrows) but all bikes are individual and best set up unique.
LTFT take it down until bad running occurs the increase value until running even range = 3.5-4.5 approx.
Keep IFT to zero for now unless access to gas analyser. (Had some fun with one of those).

Thanks metalguru

I am OK connecting the Tuneecu up as had a lot of practice recently!!

I will go through the other steps.  I have to say that I did the TPS reset, or think I did, as did not see the green light appear!  I just started bike up, no throttle, and after fan cut in I left it for 20 mins.  Oh I double clicked the reset TPS button first but I feel that the instructions for the TPS reset are a little bit vague and not sure it works! Having said that I only did it once but you suggest it may need to be done a few times!

I agree with the stepper setting as each time I set it to 25 ish the tickover is very high.  It is a little high since I put it back together last night, around 1500 rpm but as I did not have the Tuneecu connected I could not see what it was set at, will check it.

My LTFT is at 4.2 just now but will move that too and will leave IFT as you say.

Will post back

Cheers

metalguru I was looking through some old posts and noticed that you said, back in 2012, that you had a great modified 10173 map that gave good town riding and allowed you to chase sports bikes higher up!!!  Do you still have that map and if so would you be able to email it to me so I can give it a try?

I am still messing around with stuff on the bike and am still not convinced that the TSP reset in Tuneecu works!  I double click on 'reset TPS' the little icon next to it flashes a few times then message says TPS reset done.  I then start the bike and let it run for a couple of mins but that little 'greyed' out area next to the TPS never changes colour so not convinced that is the way to reset it!
Title: Re: 2005 Tiger 955i stepper motor help
Post by: metalguru on September 05, 2014, 02:45:55 PM
Yes I still have the map as still use for setting up bikes.
The TPS does work as can be proved by resetting the TPS and noting the value in the Diagnostics screen in the Throttle voltage box. The voltage will stay between approx .54-.66 as a rule and the value next to that will change from 0.0 at reset to approx 4.4 or anything in between as these bikes are unique to require to tune. Try taking the stepper to -10 to -12 and see what happens, perform blip test.
Please read the text again as nothing takes a few minutes when mapping is concerned.

PM me your email and I can send a map to you, BUT and that is a very BIG but, when maps are altered they really only work for specific bikes and riding styles, it would be a good idea to get yours running to std settings first so a unified start position is established BEFORE any map mods take place.

Just saying after years of messing with these. To give you some idea, the ECU is a modified Peugeot car ECU....Nuff said.

Post by: nigeh on September 05, 2014, 08:18:31 PM
Cheers mg.

OK I can see that the TPS setting sits at 0.2 then goes to 2.6 and on tickover it is 0.59v and increases as I accelerate so guess it does work even thought the light does not come on on the Tuneecu screen.

Bike has the Triumph race can and K&N filter so need the TOR tune at least!  I use the bike for mainly fast ish motorway riding when in England or in France wringing it to within an inch of its life trying to keep up with my mates 1200S multistrada  :icon_mrgreen: so I need as much power over 6000rpm that I can get my hands on!!

I must have something else wrong, maybe a dodgy coil?

I have put on new stepper motor, TPS, plugs, vacuum hoses from IACV to inlets and from airbox to ECU, new inlet manifold gasket, checked the shims it has a newish battery holding good volts and hours of messing about, and I am not a patient man when it comes to trying to sort my own bike out (am patient working on friends bikes but not my own as just want the frigging thing to work!!)

I will go through it all one last time and unless I can get hands on a coil or three to test them I will have to take drastic measures!!!!!

Will pm you

Post by: nigeh on September 10, 2014, 06:46:20 PM
OK I have now pretty much lost the will to live with this frigging bike!

I have done all the following:

New stepper motor, o-ring and gasket

New TPS

New fuel filter

New inlet manifold gasket, twice!

Cleaned K&N air filter

Balanced throttle bodies, b***ard to do!

Replaced the vacuum pipes from IACV to inlet manifold

Checked the shims

Put correct 10173 TOR tune in - Bike has Triumph race can and K&N

OH and put a new horn on!!!!

So while balancing throttle bodies the bike would 'blip' cleanly - at last!

Put the airbox back on and left filter out, bike would blip cleanly no stuttering

Put, cleaned, air filter back in and bike blipped cleanly - no stuttering

Put tank back on and took bike for a ride....................running like BA***RD  :BangHead :BangHead

So WHAT ELSE CAN IT BE?

Injectors?

Fuel relay? - read up about the relay but guess it is only used to activate the fuel pump and then does nothing and fuel pump test on TUNEecu shows as OK.

Maybe it could be the vacuum pipes I replaced as I could not get the correct pipes at the local car accessories shop so used fuel-pipe!!  Maybe this is closing up when they heat up and causing the stuttering problem??

I will put the old convoluted vacuum pipes back on and see if they make a difference!

Any other thoughts as running out of ideas!

OH the only thing I haven't done yet metalguru is blow your map in that you sent me but not sure that will cure this existing issue, want to get it running smoothly first!!

Post by: metalguru on September 10, 2014, 07:53:28 PM
5mm silicon vacuum pipe in the colour of your choice, plenty available on fleabay. Fuel tubing is for pressure not vac, doesn't like heat too.
Make sure stepper ports are connected correctly as there are 4 ports of which only 3 are used.

Spark plug condition??

Make sure Blue coilpack connectors are seating well as these have been known to cause problems as base of tank is a bit close.

Too much oil in airfilter??
Title: Re: 2005 Tiger 955i stepper motor help
Post by: nigeh on September 10, 2014, 08:06:14 PM
I will look for some vacuum pipe but as everything takes for ever to get in France it is very frustrating waiting for it all the time, I want it NOW not in 6 days time!!!  I will put the old ones back on and try them as I was concerned about using fuel line!

Yep stepper is fine, the fourth take-off is blanked off so they are all correct.

OH forgot to say on my list.... New Spark plugs too!!

Connectors on coils have been taken off and cleaned and sprayed so sure they are OK.

It did have a fair bit of oil in the K&N filter so cleaned that out with brake cleaner then blew out with air line and re-oiled so all good now!

And STILL running like a croc of shite  :BangHead

What are the symptoms when it runs badly? How is the bike being ridden when bad running starts?
Title: Re: 2005 Tiger 955i stepper motor help
Post by: nigeh on September 10, 2014, 09:48:39 PM
The symptoms are a stuttering under brisk/hard acceleration almost like there is no fuel getting in!

It could be that the vacuum pipes are imploding as I have not used the correct tubes having said that it is pretty much the same symptoms that started all this off 8 weeks ago or more after the bike had stood out in the baking sun all day!  It had run faultlessly on a 3000 miles trip just 4 days before and then suddenly started playing up and I am convinced it was caused by standing in the sun all day. 

I am sure it screwed up the stepper motor by trapping the plunger, due to the heat and that fooked up the thread on the plunger so that no longer worked then I have messed with stuff, etc, etc, etc

Post by: nigeh on September 10, 2014, 10:50:43 PM
I did think that at first as I filled up at a different fuel station to normal!  The problem then appeared after approx 90 miles although, and this I am certain of, the bike ran perfectly for those 90 miles and then I stopped it and it stood in direct, baking hot, sun for 6 hours and that is when the problems started.

Since then I have used all that fuel, and then filled up at a local station and used SP98 instead of the usual SP95E10 that I have been using for the last 6 years or so!

I pretty much emptied it out when I changed the fuel filter and the little 'sack' was clean as a whistle!

Have you fitted a new fuel filter, the one inside the tank?

Not had any of those fault codes just the usual ones when you start bike with tank off, air box, fuel level and there was another one but every time I clear them when I put it back together I do not get any fault codes again.  Wish I did as that would sort it!!

Yep changed the big filter inside the tank.

Kind of a long shot, and no idea if this is true of the girlies, but how about fuel tank vent blocked? Run it with the cap undone and a bit of tape to hold it down.
Title: Re: 2005 Tiger 955i stepper motor help
Post by: metalguru on September 10, 2014, 11:52:06 PM
The coil stick resistance should read 0.8 OHM.

The connectors on these coil stick can play up. Also corrosion where they join the plugs. Had similar symptoms before on another Tiger. Remove lower boot on coil stick and clean out corrosion and dirt.

The fuel pipes (short ones) in the tank either side of the fuel filter are in good condition? They can wear loose and need to be clipped.

Tank vent and drains clear? Use a stiff wire to clear, they always block.

The hot sun bit has got me thinking, have you checked the main key switch connections, these can deteriorate with age. They de-solder.

Not so troublesome on later Tigers, the crank sensor gave a misfire when engine is hot or air gap is less/more than 1mm.
Title: Re: 2005 Tiger 955i stepper motor help
Post by: nigeh on September 11, 2014, 08:58:29 AM
I have not checked the coil stick resistance, I will check.

When I put the new plugs in I noticed that the springs that push on to the plug tips were a very loose fit so I 'squeezed' the end of the springs closed a little and I could certainly feel them push on to the plug tip and when I tried pulling them off again they had gripped well. There was no corrosion at all, must have been lucky as read that water can get in and corrode the plugs, etc but mine is very clean.

The short pipes either side of the filter are in perfect condition and the clips all good, I did notice that the pipe spun could twist on the filter and pump but I could not pull them off the filter, etc.

Bike regularly suffers from a blocked drain on the tank, so much so that in the past I have had plenty of water pour in to the tank when I fill up!!!  I have not had the fuel vent pipe block but I always keep them clear and yesterday I blew my airline down them and they were clear.

I have not checked the main key switch, yet!

Not looked at the crank sensor at all.

The weird thing is that it was 'blipping' cleanly before I put the air box on, then tried it with air box on and no filter - fine, then, after I cleaned the filter and put back in it 'blipped' cleanly, then when I put the tank back on it started to play up again!

I am not sure if it has squashed those vacuum (fuel) pipes I put on so I have put old convoluted ones back on.  The old ones seem fine as when I held my finger over the end and blew down them there are no leaks.

As you can see I have covered pretty much all the bases and am loosing patience with it now!

Will report back when I have run it up again today.

I think you've covered the fuel issue. Reason I stressed this as I've "emptied" tanks before and actually looking inside I was  :bug_eye by the amount of cr@p still in there.

Yup, really pointing towards something getting nipped when the tank goes on then.

Post by: Bixxer Bob on September 11, 2014, 04:34:37 PM
Did I not mention water in the fuel earlier on?  Symptoms when I dumped an eggcup-full into the tank due to a blocked filler cap drain were exactly as you describe.  In my case, it had been doing it for a while, unnoticed, until the last lot of water.  The  water sat below the fuel pick up until there was about half a pint in there which was enough to make it  into the fuel pickup and even then only while riding.  After a 40-50 miles it sucked enough water through to run clean again. Fortunately, I emptied the tank and found the water before it did any lasting damage.

Then I cleaned out the filler cap drain.... see "The jobs you really should get round to" thread.
Title: Re: 2005 Tiger 955i stepper motor help
Post by: nigeh on September 11, 2014, 06:38:38 PM
Have to admit that I did not take more than a cursory glance in the fuel tank when I changed the fuel filter but I have run a lot of fuel through it now and have not had the 'pooling' of water inside the fuel filler cap for a while now as make sure I keep that drain clear.

I am not sure if I am reading this correctly but I have checked the resistance across the two posts on the coils today and seem to have some readings much lower than the 0.8 I was told to expect.  On each of the coils the reading keeps fluctuating building up to a max of 0.7 then dropping back and kind-of settling at 0.4 this seems lower than the figure I have seen but surely all three can't have gone at the same time, can they???

BB I used to get a lot of water pouring in to the fuel tank but that never seemed to cause any running issues and as I mentioned it has not happened for a while now, the water in the fuel that is!!

Any thoughts on the readings for the coils??
Title: Re: 2005 Tiger 955i stepper motor help
Post by: Bixxer Bob on September 12, 2014, 01:26:57 PM
If the water didn't cause it to run rough you didn't get enough to reach the fuel pickup.  I've just been down to the shed and measured a spare coil stick,  it was 0.4 ohm.

Static resistance won't tell you whether it's breaking down under load.  I have an untried used set you can borrow if you cover the postagealthough it might be Justas cheap to get a set off Ebay.  Any Triumph coils stick will do - TT600 etc

Interesting that you had the same Ohm reading on your coil!

Thanks for the offer of trying your spare set and for the link, I had a look on fleabay at some of the other listings too as would like to get a set off a newer bike, or maybe brand new, if I decide to go down the route of replacing the coils.  Be interested to know what readings others have had.

I am full on for next two days changing the discs and pads all round on the car so have decided to step-away from the bike as spent far too many hours getting nowhere already!!

Sorry for the derail but having read your saga and then looked at were you live after P+O bailed out of Le-Harve we have always gone to Le-Mans(24 hour moto) via St Malo but because of the Bikers relay at Sees have cut across country coffee at Domfront and then flat out to Sees I see a mention in your site La Ferte-Mace and I'm thinking jeeze that rings a bell what a great road from Domfront   :icon_eek:

Chris, at least you get a decent kip on the St Malo crossing!

Yes Domfront is nice, just 20 mins from us and a recently re-surfaced road the D21 from Domfront to La Ferriere aux etangs is sooooo smooth!

If you mean the D908 it is a bit too straight for me!!  Nice ride as forest either side of the road but if it was me, and you have the time, I would ride two of the nicest roads near to us!  Just before St Hillaire du Harcouet, on the D976, turn left onto the D999 to Brecey then in Brecey turn right onto the D911 to Sourdeval then D911 to Tinchebray. At Tinchebray turn right down the D22 to Domfront then take your normal route to Sees!  It is a fair detour BUT you will not be disappointed subject to the weather being good as those roads are a real treat, normally go for a ride out with guests if I have time and the poxy bike is working!!!

Whereabouts are you in Birmingham? I go to Shirley/Solihull to family and friends a fair bit during the year!

Update!

I took bike in today and bottom line is the mechanic seems fairly certain I have a faulty coil!

I have ordered a new one and will commence the 'coil shuffle' as soon as it arrives which will not be until middle of next week if I am lucky!!

So fingers crossed that is the problem.
Title: Re: 2005 Tiger 955i stepper motor help
Post by: nigeh on October 05, 2014, 07:25:48 PM
Final UPDATE.....hopefully!

The new coil arrived the other day and I got round to working on the bike yesterday.  I decided to go for the middle coil first as when this all kicked off I vaguely remember doing the 'wet finger' test on the header pipes and thinking that the middle pipe was not as hot as the outside two!!  I put this down to a dodgy spark plug and never checked it again.

Looks like I was in luck as no need for the 'coil shuffle' the NEW coil was fitted on the middle plug and she runs like a beaut now  :hat10

Went for a 60 mile ride this afternoon and is great.  Rode her down to 25 mph at 1500 rpm in 6th gear and would pull smoothly from there no hesitation or spluttering.

I am now a happy bunny and would like to say thanks to all those who posted their thoughts/advice especially BB and MG, many thanks.

Bike is now running better than it has for a long time so well worth all the parts I have changed over although could have done without the £350 outlay as could have got away with just a coil but hey-ho should run for another 42,000 miles now!

Thanks John

It has been a fairly long slog to get to the bottom of it but have to say I now know the bike well just have the following to do over the winter:

Change anti-freeze
Change brake fluid front and rear (boiled back brake on a pass in Italy so needs doing  :hat10)
Replace header pipe gaskets
Change springs in forks for harder ones and heavier fork oil as dives way too much!!
Service brake calipers all round

And bound to be other stuff but would like to start on renovation of my 1988 CR500 as been promising myself to start that for last three years now!!

Chris... I am always chasing a multistrada as mate has a 1200S which is why I am always looking for extra ponies for the old Tiger!!  I wish it was just a case of changing the cams for the daytona 955i to unleash power up to 140 bhp ish but sadly not!!

Sadly not,to compete against a 17 wheeled bike you need one and that's not possible(well I don't it is!) with the later bike(earlier yes) but springs 15wt and a decent shock will go an awfull long way,my encounters with Multistrada's have always been favourable but that's my 10 years of setting the bike up against what a man thinks you want at the factory suspension wise at the push of a button.

There's little point in me going into my drama over the years with my aftermarket rear shock :icon_scratch:, and ultimately you can't get the motor to produce another 20hp because in real terms it's not lots more than that but there's loads you can do with your tiger suspension wise.

I did meet a guy who told me he had finally sorted his Tiger out and it was all about suspension!!  He had spent £1500 on it, ouch!!

I have just put a 'newer' stock rear unit on as mine had done 42000 miles and the one I have just fitted has done about 8000 so must be better and I plan to do mods to the forks as stated in earlier post so let's see what that does!

I've got Ohlins front fork spring 15wt and more than the stock quantity with a Ohlins on the rear that's now on it's second spring and 5th revalve and hindsight being the wonderfull  thing that it is I'd have gone to Maxton right at the beginning.

Final UPDATE.....hopefully!

The new coil arrived the other day and I got round to working on the bike yesterday.  I decided to go for the middle coil first as when this all kicked off I vaguely remember doing the 'wet finger' test on the header pipes and thinking that the middle pipe was not as hot as the outside two!!  I put this down to a dodgy spark plug and never checked it again.

Looks like I was in luck as no need for the 'coil shuffle' the NEW coil was fitted on the middle plug and she runs like a beaut now  :hat10

Went for a 60 mile ride this afternoon and is great.  Rode her down to 25 mph at 1500 rpm in 6th gear and would pull smoothly from there no hesitation or spluttering.

I am now a happy bunny and would like to say thanks to all those who posted their thoughts/advice especially BB and MG, many thanks.

Bike is now running better than it has for a long time so well worth all the parts I have changed over although could have done without the £350 outlay as could have got away with just a coil but hey-ho should run for another 42,000 miles now!

Cheers  :icon_salut:

Just as a matter of record when Bixxer looked at mine last weekend the screen shot said middle coil ordered one fitted this morning only ran the bike up for 30 seconds to realise it was a Eureka moment  :icon_biggrin: so it it pure luck or is the middle coil prone?

Nice to get something right though eh Chris??

For anyone that's interested, I looked at Chris's data with TuneECU and noticed that although it was the best running 955 I've looked at, the dwell interval on the middle coil was running a about 1.7msecs where the other two were about 1.67 -1.68.  The dwell interval is the time it takes the coil to recover from generating a spark so the middle one lagging behind the other two suggested that it was on it's way out.  A slow recovery means a weaker spark next firing etc... 

Good to know it made a difference. :thumbsup

Sure is a result.  The last faulty coil I had was on my first big bike, an XS750 back in the early 80's and never had one go since, funny that the XS was a triple too!!!!!!
