OK finally some good news about my bike. I just received the Race ECM Do I have to do a TPS directly or can I install it and run it as is for a while? It is difficult finding someone doing resets here, and it would be nice to get some positive feelings towards bike again before finding someone to do the reset. |

I just recently purchased a race ECM from Bartimus here on this site. I asked the same question and he said to just run the bike at 3500 rpm for 5+ miles and it will sort itself out. It worked! Bike idled fine but if you hit the throttle after coming to a stop it would stumble a little. I nice ride of about 20 miles sorted it out for met! I have been riding now for over a week everyday without any issues at all. |

Guys, You may want to recheck your facts. If you replace the ECM on a fuelie bike the TPS usually has to be reset. If you get by without a reset, you are very lucky. The procedure that Bartimus outlined for you Impala is only part of the equasion. The steady running at 3500 RPM adjusts the air/fuel ratio. It does nothing for the TPS setting. The TPS (Throttle Position Sensor)is a variable resistance pot on the side of the throttle body. It's attached directly to the throttle shaft and plate. The ECM has to know what value coming from the TPS is "zero throttle". The value is measured by the voltage drop across the variable pot. Only then can it determine exactly how far the throttle is open. The zero value is set with the idle speed setscrew backed out and the throttle plate closed all the way If you just slap in the a different ECM, there is no assurance that the "zero value" stored in the new ECM is the correct value for the rotory pot on the throttle body on YOUR bike. A TPS reset is the best way to go. It can make a BIG difference in the way your bike runs especially at low RPM's. There are many on this board that will attest to this issue. Brad |

+1 on the TPS reset. I had 3 different dealers tell me that I didn't have to zero the TPS after installing the race ECM. I even begged one to do it and they didn't (?). Thanks to Naustin and Brad I finally got it taken care of last fall and the bike starts and runs better a low rpms than it ever has. Iowa Mike |

OK then, will do the TPS reset and it will maybe run EVEN BETTER than now! I was just out for 2 hours with such a smile on my face!! Even the idle is PERFECT (also when engine is cold!) |
