So you're trying to tell me that in each individual gear your acceration is a constant? Even though engine RPM is changing and when engine RPM changes your torque changes. Then why not run each gear to the rev limiter even on a stock motor? After you pass peak HP you will reach a point where your acceleration will be greater in a higher gear. My whole point is, the track times will be off by a different number for every car. And since the track times won't have a consistent error for every car, neither will the GTechs. I'm sure that there is some car that could run the 1/4 with a GTech in the car and the GTeck would match the ET and MPH exactly. It depends on the car. And given the amount of variables that are present when running a car down a track, you're never going to be able to accurately calculate acceleration. And using an average is not helpful because the range is so large and you are making a calculation of error using one end of the range (the end of the track)
About the change in RPM and difference in gear ratio. Not all engines make more torque at 4000 RPM than they do at 5500. My whole point is, without knowing the torque and power curves of the engine, you cannot accurately calculate acceleration.
