hi I'm angelo from italy xb12s owner ( is just the 2nd) many people here had find some problems with the prorace ecm , many hole due to a problem on the memory of the ecm , have you hear something in about ? thank you | ||
| Buckinfubba |
not sure I really understand what "memory " you are talking of. If you mean the tps sensor...well its real easy to set those wrong. what problems are ya having | ||

Nico - Buen Venido a la Bad Web (Spanish welcome). Yo no e visto una problema con la computadora. Si ay un poso, pero no es culpa de la computadora. De que problema hablas amigo? Tu Amigo, Felipe | ||
| Buckinfubba |
damn it I am to stupid and uncultured...what? ciao | ||
| Nicozzzz |
thank you anyway isn't due to the TPS is due to the ecm that lost his memory data, for example ( this is happened also to me) : you use the bike for 2 hours, after you will stop for a while , when you start again the bike is full of hole on the firs 3.500 rpm and sometimes the engine stop . and you also find some problem in start it . this is the problem some people say that is due to proseries ecm that lost his data memory | ||
| Buckinfubba |
it still could be the tps or some other sensor. engine temp andsuch. but trust me the TPS is the first place to start. it runs and starts fine when its cold but when shut off after a few hours it starts hard. what pipe are your running the buell race pipe or what. just asking questions to try and help. if the engine is just stopping while your running. check for lose connections or relay or diode troubles | ||
| Nicozzzz |
thank you for your help, I had the proseries kit, my bike is not giving me many problems, only sometimes she does this jokes. when the engine stop usually I was at the croslight or at very low speed , you must put bring the rpm about 3000 or the engine will stop ( i repeat she does it very few times) in other xb12 the problem is most frequently, and many people had hear that the problem is due to emc . | ||

You might want to also check your engine idle speed. If it is too low, you could have stalling problems at an intersection, etc.. | ||
| M1combat |
Yeah, everything you've said so far sounds like either low idle setting (known issue - set it to 1050) or a TPS zero issue. From what I hear the scanalyzer that was used for the FI tube frames is NOT the same as the tool used for the XB's... I don't actually know that to be a fact though. Maybe your TPS was reset using the older scanalyzer as opposed to the new digital technician?? | ||

All this sounds too familiar to me ..I am having a similar problem with my 12s and the Tech that is working on it is having a hell of a time figuring out what is wrong with it ...Can anyone help ? | ||
| Spyder12s |
Why is it every time I post everything seems to stop? ..Or is it just me? I am going to get a complex !! | ||
| M1combat |
LOL  . I don't know what the problem is, but it SOUNDS like a TPS reset issue... I wonder if there's a battery in the ECM so it doesn't have to be on a live curcuit when the key is turned off? Like a BIOS battery in a PC? | ||
| M1combat |
If that's the case though, it suggests that the ECM is VRAM as opposed to NVRAM which in turn means it could be "re-burned" with a different fuel map... Actually, it would have to be that way for some portions or it would have to re-learn the AFV each time it was started... Anyway, don't mind me... I'm a fan of tangentiality... | ||
| M1combat |
Or maybe tangetialism... Or I'm just a tangentialist... Who knows . | ||
| Spyder12s |
Thanks M but that does not get me my bike back ...I want to ride damn it ... the issue that I am having is the thing will not idle consistently when it is "hot". the tps has been reset many times now and nothing, that is why he (my tech) is digging deeper now ..LOST.. is what we both are right now. even going back to the stock ecm the thing is not right ... | ||
| M1combat |
Is he resetting the TPS with the wrong tool? I would maybe ask him to call Buell and make sure that the tool he is using does indeed reset the TPS on the XB... I just seem to remember reading somewhere (may heve been my manual...) that the old "scanalizer" tool will not reset an XB TPS properly. Is the CPS (cam position sensor) out of adjustment? I hear that has symptoms like an outta whack TPS. Is the O2 sensor bad? I hear the ECM works in its non-learning (?open loop?)mode when cold, and only uses the O2 sensor after warming up. Anyway, sorry for leading the thread slighly off track. | ||
| Spyder12s |
YEah after talking to him today the O2 was bad, staying close to the 5v range not fluctuating as much as it should. as far as the tps reset tool I would think he is using the proper one where as he was at Buell school last week ...but the cps is not something that has been brought up ...thanks again | ||
| M1combat |
Glad it's fixed | ||
| Spyder12s |
did not say it was fixed ...not back together as of yet ...keeping my fingers crossed ... edited by spyder12s on April 09, 2004 | ||

thank you to everybody for your replay, please spyder keep me informed on your discover on the matter . greeting from Italy | ||
| Spyder12s |
will do buddy ...I know that he found that the rear header bolts very loose ...and the bad O2 ..so far ... | ||

When zeroing the TPC on a new ECM it's also advisable to set the AFV at 100%. Sure sounds like TPS induced symptoms to me. Below 3000 rpm the bike is trying to run mostly in open loop mode and is effected greatly by TPS calibration. Nikozzz, Sorry to hear of your race ECM difficulties. Please ensure that your technician is unscrewing the idle speed adjustment screw completely, so that the throttle is 100% completely closed, BEFORE performing the TPS reset procedure. If the throttle is not closed completely during TPS reset, the procedure will yield problematic results. I would be very surprised if the problem is in the ECM itself, but once you are certain that the TPS reset procedure is being performed perfectly, ad you still have problems then you may be onto something. The fact that Spyder is having similar problems is somewhat suspicious. Ciao, Blake Spyder, | ||

spyder: the O2 sensor cannot output 5 volts. loose header bolts can cause extra air intake to the exhaust, leaving an apparant lean mixture for the ecm to respond to. this would cause very poor warm engine performance, but would not bothe r it at all when cold. if you are sure that you are measuring 5 volts, that is a bias voltage output from the ecm. again, an O2 sensor can not generate 5 volts, but this may point you in the direction of your problem. | ||

There's an article in the KV that says exactly how to do a TPS reset. Maybe print it out and give it to the tech. I think the procedure is in the service manual as well. | ||
| Spyder12s |
thanks guys for all the help ... | ||
| M1combat |
Need any more? | ||
| Spyder12s |
is possible ...who knows | ||
| Spyder12s |
My tech knows what he is doing I am confident of that but the issue will not go away ...the bike does not want to idle .. it is "skipping" at idle. seems to be from what I experenced, when it is warmed up or "hot" but at this point its frustrating !! for both of us .. He is going to call Tech line on Mon. Man this sucks !! | ||
| Fullpower |
and the trouble codes are?? |
