Do you have to perform TPS reset when changing from race ECM back to stock ECM and then back to race? I ask this question because when traveling across Europe, in some countries you have police problems with a loud exhaust. So before each trip switching to stock ECM & exhaust is a good idea. Then when you get back home you have to change to race. Do you have to go to the dealer for TPS reset each time? Also I was wondering if any of you have experimented running a race ECM with a stock exhaust and having the power valve fixed at the open position. How does this perform ? Will the air/fuel mixture be too lean and cause problems? This will save the trouble to change from race to stock ECM. | ||

I don't think you'll have a problem running lean with the Race ECM and the stock exhaust. I'd expect you to run rather rich instead. Infact, you might be so over-rich as to cause other problems. But you'll have to investigate that more with the experts. Nick (Message edited by Blake on October 27, 2006) | ||

Nick, Switching ECMs does not necessarilly require a TPS reset. A new TPS reset/rezero is required only if the ECM is new to that motorcycle, or as you say the TPS itself was fiddled with in any way. Not sure what you mean by "disconnected", but merely unplugging the lead to the TPS would not require a new TPS reset/rezero. Only ECMs that have not yet been installed and subject to a TPS reset on that particular motorcycle require a TPS reset. An ECM retains its last TPS rezero/reset. So, if you have multiple ECMs, as long as each one has been at some time subjected to a TPS reset/rezero, and if the TPS has not been adjusted, replaced or fiddled with, then one may swap ECMs at will with no new TPS reset/rezero required.  | ||

The way Nick wrote that may not have been perfectly clear. "everytime you switch the ECM" means every time you switch to an ECM that has not been on the bike before. If you put an ECM on the bike, reset the TPS, take it off, and put it back on, you do NOT need to reset the TPS if there has not been a change to the TPS or throttle body. The setting is persistent and doesn't change. At least over a reasonable amount of time. The sensor can wear a little over a longer time, which is why a TPS reset is recommended at 10,000 miles service intervals. "disconnect the TPS sensor" means mechanically separating it from the throttle body, NOT electrically disconnecting it. You can disconnect it electrically all you want and that won't change the voltage the TPS outputs when the ECM reads it when the throttle plate is fully closed. But if you separate it from the throttle body, that WILL change the zero position voltage when it is reattached. Al | ||

Thanks guys. I didn't know that and I'm glad you clarified it...  | ||

Just a random ECM-related FYI- Be cautious if you find yourself changing ECMs somewhat often. The combination of tapered, self-cleaning bolts and a magnesium fairing bracket make it easy to strip the threads. I stripped one of the holes on mine but was able to get away with using a slightly longer bolt that was threaded the whole way. | ||

Thanks for the answers. Once again it was clear. But still, is it OK to run a race ECM with the stock exhaust pipe and its valve fixed open? I have just received from Americansportbike (Thanks Al !!) the race ECM and I plan to install it on the bike. I am also waiting in the next 2 weeks the Micron exhaust system. It would be easier for me to visit the dealer this week, install the race ECM and reset the TPS. Then I have 2 options: 1. Go back to stock ECM and wait for the Micron and then change both of them at home since there is no need to reset the TPS again.(To the dealer it is a 2 hours ride) 2. Keep the race ECM on and fix open the power valve on the stock exhaust. Then when the Micron arrives replace exhausts at home. What do you suggest ? Al , I was amazed that it took 1 week for my order to reach Greece from California. Also the t-shirt is really good. But I realized that the Large size in the US is much bigger the Large size in Europe. Also I must say that the job done for the exhaust comparo is AMAZING!!! It really helped me make up my mind. Now I can't wait to get the Micron on the bike. Finally just got back from a ride around twisties with my new Pirely Diablo Corsa. The bike with these tires on, is PERFECT. It does NOT stand up at braking mid-corner no-matter how hard I tried. It turns in very easily and holds the tightest line that can be imagined. The lean angles and corner speed are UNBELIEVABLE. I cannot believe Buell released the XB with the Dunlop 207Y on, and let themselves to bad critics about trail braking and crap like that. They should have gone to the Corsas from the beginning. At the factory they should have a word with their test riders. For example the new Triumph 675 was released with the Pirelly SuperCorsas on. After the first tests in the magazines it is now considered the best in the mid class. I wonder what the verdict would be if it was tested with the 207s on. But I guess at Triumph the test riders did a better job and chose a tire that would suit their bike and amaze everybody, rather than something (slightly cheaper?)that will give trouble . Also, I hope Nicky does it for you Americans and beats Rossi tomorrow. |
