    Default Weird spark issue.

    Hey guys,
    So I'm at the track doing some testing with our 2010 camaro. It's procharged with a 4L80 conversion, zr1 map sensor. I'm having a hard time. It's pulling timing from 5200rpm and up. Is it because the ecu doesn't recognize a trans (since its standalone, thinks its in neutral) or is it some weird torque setting/ map setting? Or something else that I'm missing. I've been going through the tune trying to narrow it down but I feel like I'm missing something stupid. Can anyone shoot me in the right direction? I can't post a log because I'm on my cellphone right now.

    How much is it pulling 1 degree or 10?

    It varies but it's bringing my final timing way down (5-10 deg). It's driving me crazy

    Try reducing b5156 Max spark retard, as long as its not knock causing the retard, that is what i would try next. If you have torque reduction shut off b0515 that is.
