Thread: has anyone had vtd problems after bench flash of costom os

  1. #1

    Default has anyone had vtd problems after bench flash of costom os

    I installed new 6.0l engine in the truck, in the process did a custom os upgrade (03) and reflashed calibration. Reassembled vehicle and everything is working except no spark and a flashing vtd light on key up. The vehicle is a 03 Silverado upgraded to 6.ol with etc, sts turbo, methanol, boost controller and now no spark! Does Efi live do vtd? maybe I am looking right at it and not seeing it!!!!
    Thanks for the input.

    O.K, so a seriously late reply, but..........
    You can set the VATS to relearn on a full flash........or at a last resort, turn it off. Quite a few mail order tuners will turn it off just to be safe. How did this work out anyway?

    Cheers,
