    new to tuning need tune help

    I am putting a 5.3 in a demolition derby car. I programmed module. can anyone look at tune to see if it will not go into limp mode if it gets hot? if fuel table is rich enough?

    thank you

    If it's a 5.3 then a few things are wrong.

    Cylinder volume says it's a 6.0, so fueling will be wrong if you don't change that back.

    Why did you apply the 2 bar speed density OS to this file? Go back to the stock file if you are not running boost. If will never run the way it is with the 2 bar OS and an unpopulated VE table.

    The stock full throttle fueling is richer on the stock file than this file, so another reason to change it back.


    You're biggest things are turning off trouble codes for stuff you are using. You can't run o2 sensors if this will be open headers and you need to maintain roughly 55-58psi of fuel pressure at all times to make sure it doesn't grenade from no fuel.
    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.

    You can't set every single DTC to 'no error reported'. Just can't. Don't do that.

    Longer answer: Because the PCM needs to see the diagnostics run before it will use certain components and run the damn engine.

    Excellent well thought out first post, by the way.
