Ok, here is the deal. I have a 92 GMC Sonoma GT with the 4.3 CPI engine and 700R4 trans. Ive been trying to get datalog software to work but it seems this is a one year only system that no one has ever written the needed files to actually talk to the ECM. My original ECM is the 16156647 Chip Code BCBH superseded to CBJZ in 97. Def. file is a D5A.

Anyways, i know i can datalog and tune the 16197427 as they used this ECM in the 93 S10/Sonoma with the 4.3 CPI engine, but 93 was the first year for the 60e, and i wanted to see if i can use this with the 700R4 as well?
