Good morning,
I swapped / re-pinned my 1996 GMC 5.7L Vortec to an 0411 ECM, I cannot get it to idle. It will start but not idle, I have included the tune file and scan file below.
The current tune was segment swapped with a 2001 Chevy Express Van only with engine and engine diagnosis information.
The 0411 ECM is from a Chevy Astro Van V6. Need some help...
