Tom, I see what you are saying and it is very unfortunate that there are dealers that apparently have no clue or very little of one to put you all in this position. There is a very easy way to correct this issue, but the Actia data can't just be read...It has to be understood. Keihin has been very forthcoming with information on haw these fuel injection systems work, but technicians have to also understand what is actually happening in the system. What I was saying about the TPS is that it in itself is adjustable, so to get to .6v @fully closed throttle, you just MOVE the Primary TPS, not the throttle plates themselves. Also, the Stepper moter does have a value range to reside in at idle. If it's not in the range i.e. low, the plates aren't open enough, there isn't enough air flowing which doesn't complete combustion so the O2 sensor reads a rich condition and backs off fuel. Of course it's exactly the opposite if the stepper values are high @ Idle. The MAP sensor can only read from 0-12% because it reads the pressure differential between both sides of the butterflys. After 12% the plates are open so far that there is not enough pressure difference for it to read and compare against the barometric sensor elswhere on the bike. So losing almost 20% of its read capability could be an issue. I have read your post and I have most certainly read the Service Manual since it is on a shelf above my desk with 40 other Triumph and Ducati Service manuals.....I do know a thing or two about Fuel Injection, but I will not get in a pissing contest about this post, I only intended to offer an experienced perspective on your post Tom. It is so well written and obviously appears to work well and I'd like to know what it is about it that works. But I'd rather not see people doing this in a way that creates a larger problem, as is capable of happening with "you results may very advice". Again no offense intended, i'd rather be able to offer you all advice in your time of need. If possible.

Cheers

If you just MOVE the primary throttle potentiometer very far off of the .6volts @ fully closed throttle guess what happens? It goes into a failsafe mode and the motorcycle will barely run. So... you must adjust the throttle plates and then re adjust the primary throttle potentiometer to show .6 volts. And... I am not closing the throttle plates during my adjustment, I am opening them up just a bit. When the bike goes into closed loop the system will take care of itself as far as the air/fuel alpha goes.

This is fully reversible. As I said before... I would exhaust all attempts by your Triumph dealer to fix this before doing this.

Many different dealers from around the world have tried to fix this. New stepper motors, reloading tunes into the ECM, adjusting the base idle rpm's by using the Triumph scan tool, using the 12 minute tune, balancing the throttle bodies, checking sensors (like the primary throttle potentiometer)... none of this seems to fix the problem.

Keeping that in mind... we eagerly await your fix....

Anyone with this problem want to bring me your Rocket? I have none with this problem....lucky for me I guess....sounds like a daunting problem :???: But seriously I would help any of you out in a heartbeat with any problem you might have!

Cheers

My 05 rocket has had this problem since it had 2500 miles on it last july , was worked on at more than one dealer until oct. and has been at the dealer since then . Thats 6 months! and still does not run , mine wont idle hot or cold , Triumph says they don't know what to do . I am ready to try anything ! The bike ran fine at first then were riding one day and it started to have a fast idle when ever i tryed to slow down then within 15 min. it started to slow idle and has been thier since . Bike is bone stock .?

Wow, isn't that great? So you've just had a scary thing happen, killed the engine, and, pumped and nervous, start it up to find your day has been made even more exciting. There are times when you really don't want your bike to change its behaviour :-\

I have to do a 100-point turn in my drive to reverse into my garage each evening. With the engine running, I'd die from the fumes. I have the alarm fitted, so if I turn off the ignition it sets itself before I've finished pratting with the bike. I'm manouvering, so I don't want to put the stand down, so I have to turn the ignition off and on again: I'f far rather just use the kill switch. Thanks, triumph, for putting a big shiny useful-looking thing in front of me that breaks my bike. (I'm in a mood because I tried it last night and it took ages to get the bike running this morning and I was late for work and now I'm wasting even more time reading/writing this).

At least you're still alive geezer... had gone horribly quiet for a while and didn't like to ask!!...

Rhino... You kill me!! So now you are wasting time posting here with us?? You were the single most prolific poster on one thread ever... Suck us dry, then tell us it is now a waste of time!? Yeah... I thought you had killed yourself too... Probably while doing your 100 point turns down your freaking driveway. :hammer: :razz:

I'm reserving dying for this evening when I have to ride home on a new rusting thing with bits that spontaneously fall off and that thinks idle is about 60rpm.

If I survive I'll sell it and buy two BMW F800Ss and may even have some change left. Or will I be hopelessly disappointed having only experienced the R3?
The R3 looks so wonderful. Why do I feel so let down?

I deny everything!
Theres no evidence... :lgh:

So how do I do a 12 minute ecm reset if I can't start the bike without touching the throttle because the idle is too low?
If I stuff a bit of cardboard as a spacer on the idle stepper lever that'd start it without touching the throttle... or is that the same as touching the throttle?! I literally only need to twist the throttle 1mm after taking up the slack for the idle to be fine! Soooo frustrating!
