    2010 Camaro SS 6.2L Cuts out and scanner stops working

    I have a 2010 Camaro SS 6.2L NA that a friend brought to me with an issue of cutting out above 4500 RPM. When I drove it, the engine seems to cut out if the RPMs are above 4500 and the TPS is roughly above 50%. If you don't go past 50%, it will rev to the limiter. He said this happened after he watched a YouTube video that said to remove fuses 5 and 20 (both ECM fuses) to reset the fuel MAP to high octane.

    I have checked all the connection and grounds, and everything seems good.

    The modifications include:
    Cam- Not sure the specs but it sounds big?
    Headers and full exhaust
    LSX intake
    MSD Coils and wires

    Scan #1 is WOT until it cuts out run 1.hpl
    Scan #2 I held it under 50% until I got to 6000 RPM run 2.hpl

    The tune by others- original 10.23.20.hpt

    Any help and or advise is greatly appreciated,

    You only have about 6 degrees timing at wot. That might do it.

    I believe that was the TCS removing timing. Here's another run that is WOT in a higher gear so the TCS was not a factor after 5200 RPM.

    That run also shows the TCS pulling timing around 4200-5300 rpm. Did it misfire above that rpm? If so, it's likely his coils. I've had numerous MSD LS coils fail. Hopefully he kept his original coils. The original ones are much better. It's also possible that it's a plug wire, but I'd say coils are very likely.

    Yes it misfires above that point as well and then the HPT scanner quits logging at the same time. We don't have the original coils, I will try to track down some OEM coils and try that. Thank you for your input!
