    Gen 3 5.3 Stock Learning gas tuning

    Hello all i have a 2001 suburban with module P01, pulled my stock file, updated the speed density OS, did some data logging so far. Right now my fuel system #1 is at CL-fault, I am wondering if fuel system #1 and #2 on data log channels correlates to the B1 and B2 or oxygen sensors

    until you post up your tune and log we cant do anything to help you at all.
    also you need to tell us about your engine, and other modifications you have done, such as exhaust.
    you paint the picture for us to help you.

    and why are you messing with SD os?

    My exact question, why would the first thing you do be adding the speed density OS?
    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.

    Will add log file in the morning, and I try to update all the OS before doing any tuning

    Figure it’s best to keep things up to date, then again I am new to this, tuned my cummins once after an engine swap to the best of my ability now trying to learn gas

    Some of the early SD OS's keep the MAF from ever working even if you have it setup to do so.

    I think you'll see CL fault if there is a MAF failure.. which might be related to the SD OS

    Changing to a COS doesn’t keep things up to date. It changes it to a different type.

    Fuel trims are working. You're logging way too many pids. Need to cut out 75% of them at least.

    Gen 3 can only handle so many channels at one time.
