    2007 Escalade 6.2 (408) engine and ECU

    Working on a project that has a 07 6.2 (408) 11.5-1 cammed and ECU out of a Escalade using a truck harness. It will start and run for a few Seconds and stall. Made changes in ECU DOD off, VVT zeroed out, idle raised air flow adjusted up to 50% over stock and still no change. It is still running rich when it does fire AFR around 10.6. Anyone ever run in to this issue?

    Post the tune.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    Was a write entire done when the VATS was turned off?

    Don't forget to set the camshaft under the variable camshaft tab from one to none if you removed the VVT cam and installed a non VVT front cover.
