I'm tuning a 04 Impala SS w/ a SC 3.8 for a friend of mine.
There is no air mass PID in the scanner but it's needed to log spark.
I've read a few posts about how to calculate air mass and I'm not for sure which one I should actually use.
I also found calculated airmass in the math parameters in the scanner but I don't know if it's right or not. It seems really high for what little is done to the engine.
Any help would be appreciated.
