94-95 Mustangs Tuning MAF Transfer

Overview
The MAF transfer reads the amount of incoming air and converts into a voltage that the EEC can use.
To richen the MAF curve, increase the airflow values. To lean the MAF curve, lean the MAF values.
You can determine the exact amount to raise and lower the MAF curve by doing some math. If you are shooting for 13.0:1 and the car was actually at 12.5:1, divide 12.5/13.0 to get a correction factor of 0.96. Multiply your MAF curve in that area by 0.96 to lean it out and rerun the car.
90mm Lightning MAF Transfer
This is a curve I've started from with good accuracy on two 90mm LMAF cars. I had to lean out the upper end of the MAF to get it perfect, but the lowend was dead on when I had the proper injector settings entered.
