    Default gm.trqeng

    99 c5. what are the inputs for torque in a stock tune? what happens if you loose the maf? and how is it with cos3 and (e.g.) a 2bar map?

    (gm.trqeng seems to yield same values as gm.trqtrans. any thoughts on that?)

    edit: this is what im seeing at 200kpa/no maf. (i cant upload scan for some reason.) rising ibpw to redline, dyncylair rising to redline (1.90 max), torque peaking at 3800* with a (quite realistic for max) value around 800 nm, acceleration fluctuating but highest at 5000-6000, calc.power rising to redline with 500 rwhp max (not unrealistic, a bit low). in a stock cofiguration i see max torque at 450 nm (engine rating is 475).

    *140kpa
