self explainatory. Want to dial in the race car, but it is hard to ever "build up" any part throttle driving with a master power switch.

 

yes, fuel trims will eventualy reset if the PCM loses power

 

I guess I'll have to use STFT's and LTFT's together, as it just isn't practical to go for a long ride in this car.

I'll straight-wire the PCM "hot" wire next time I'm at the track, but it is just hard to get very much part-throttle data.
