    Default Need Help with Excessive Timing Retard in Boost - COS3

    I just upgraded to COS3 of an original 12587603 OS

    I'm getting significant timing retard when going into boost that isn't expected. I followed everything in the COS upgrade doc. The only thing I didn't do was zero out B1902 because it's not defined. I don't think that's the issue, but I could be totally wrong.

    I've read as many things as I can find online and there seems to be no obvious fix that has worked for me.

    Log: Log_0002.efi
    Tune: 7603 COS3 Base.ctz

    I Logged pretty much all the of the spark adding/subtracting pids that I could and the only one that looked like it showed any value was GM.EST_ECT_DMA but it was showing -15 degrees like all the time so I'm not sure how it only seems to be impacting timing once I get into boost.
