MAP V.S. MAF in FI engine

[mrshin]

Maybe look at Commodores for MAF meters. Also, sometimes you can mount the guts of any MAF into a different sized tube to get the calibration you want.

the factory MAF on an r33gtst would be perfect or your needs. it will read the required airflow and getting the cal tables wont be hard either, the other benefit is that they were turbocharged from the factory and are extremely reliable.
