1992 4.3 V6 CPI (L35). 1st time tuning an older V6. Using tunercat, burn2 and adapters. Have been able to read the calibration file from the memcal and was looking over the bin file in tuner. The tables looked normal but I noticed that SOME of the constants look strange... like cyl volume is "0" , number of cylinders =192, injector flow rate=1094.1 lb/hr. Looking for anyone out there that may have played with one of these and can help me out.
