    Post Z06 LS7 misfire

    An LS7 Z06 Corvette (2007) would get to a certain rpm on the race track and then the ETS would start to behave erratic, see logging:



    We reverted back to a standard tune and it would still happen, any idea why?

    Cheers, Joe

    You will see the erratic ETC a few times through out the log.

    Looks like a mechanical or electrical problem.

    The tune you posted was stock. But try changing the Accel Thresh table as shown.

    We reverted to the std tune and the problem still persisted. What’s does the "RPM Limit Accel Thresh vs Accel" actual do? Cheers, Joe
