I'm brand new to tuning and still trying to understand all the terms.
What do you mean by copy the calibration? Are you referring to the AF vs Voltage calibration?
I also realize this is a really old thread, but I thought is was worth a shot.
He's talking about copying the throttle body model. ETC Area and Throttle Angle Predicted.
If you have a GT500 or GT500 set up with the same MAF housing, you could use AF vs Voltage as well.
