I am tuning a vehicle for someone with the following setup:
Vehicle: 1978, Chevrolet pickup. Custom wiring harness.
Engine: 5.3L , 2002, Escalade
ECM: 2000 Chevrolet, 2500, 6.0L, GMP01, OS 9381344
The engine has a new BTR3121811ONSR cam, everything else should be stock.
Has idling issues but, otherwise seems to run ok. After it warms up, it will idle.
Before I address the idle tuning, I wanted a second opinion on how to proceed.
1. The ECM is programmed for a 6.0L and the engine is 5.3L. should I compare the 6.0L with a stock 5.3L calibration and adjust all of the tables?
I have a J2534 device and considered programming it with the latest 5.3L calibration before proceeding. your thoughts?
2. Idle tuning for the new cam. I may handle this one in a new thread after the above is completed.
3. I have a few log files to share and will post them if needed.
