LS2 auto Throttle Control

[oztracktuning]

Has anyone noticed how the absolute throttle position logged in an LS2 auto varies from near its maximum amount when accelerating even though the foot pedal is flat to the floor? Is this truly showing a less than 100% open throttle blade? If this is the case what can be done about this in an LS2 auto.

Stomped i didnt get 88% and it dropped from 88% well before gearchanges? Was is just this car?

Torque management?

I guess some of it is gearbox related torque reduction, but i seems to happen well before gearchanges and maybe when the car goes over a certain level of airflow??

Any difference if you log ETC TP?

I didnt log ETC TP. I think what i saw was a real TP though - so i want to track it down

Did it ever log 100%. Does the blade open 100% visually if you look at it while the pedal is held down. I have read that SAE.TP won't go past 88% on these vehicles as it is referring to a % of 5V rather than physical TP. GM.ETCTP is the PID to log.
