    GTP p04 flex fuel?

    Ive seen people os swap the LS stuff to enable flex fuel on their p04, is it possible to get this working with the v6 cars? Im rather new to HPTuners but im willing to brick an ecu for science.

    Nope.

    Those computers were never designed for that so there is no way to enable it. People still get by okay even running E85, they just need to know what they are doing fueling.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    Ah, damn. I was under the impression the p04 and 0411 were the same, and after posting this thread i learned it wasnt. I know the 0411 can enable it with an os swap. Looks like ill just need to get a content sensor for my aeroforce and keep the laptop in the car.

    Has anyone use a 0411 on a 3800??
