I am helping out a friend who put a 2001 5.3 Tahoe engine into a 70 chevy truck with a 4L60e and big thumper cam with headers. He sent the wiring harness and ecm off to have set up for the project. The company did a bench tune which ran but not very good. I would like to use the fuel trims to help line out the VE table. I cannot get the fuel trims to work. Please look and see what I am missing. Thank you!
