Hello everyone. I am new to this site, but not to ECM/PCM tuning. I am workign on a project of running TBI off of a Mass Air Flow sensor. A member of Thirdgen.org supplied me with the calibration for the newer bigger style LS1 sensor. I am actually trying to find the GM calibration used on the MAF sensor used in the 1994-1998 F-bodies and 1996-2002 Vortec trucks. If anyone can point this out it would be appreciated.
