Since the 2 butterfly L98/LT1 style TB is significantly different than the LS1 style, I thought that it might improve idle etc if I calibrated the IAC steps table to more closely represent the area of the IAC passage with each step.

Knowing the displacement of each cylinder, I assume I can use the cylinder air mass (g/cyl) to figure out how much air is entering the engine, calculate the amount of air in grams, then calculate what the change in area from say 50 steps to 60 to 70.

Hmm, on further review I'm not convinced that would work given the tortuous flow path and variable vacuum in the intake.....

Anyone have a better idea on how to figure this out in the real world?

Thanks,
Jason
