    Default CASE relearn for PCM with new LS2?

    I have a new LS2 403 going into my 99 vette. I have all the pieces in place, I think. One thing I'm wondering about is CASE relearn. I'm sure it's something I'll have to do. I've done it on my last motor, a h/c LS1 when I changed the OS, so I know how to do it. I'm wondering if anyone has experience with this on first startup of a brand new motor. I just want to let it warm up and look for leaks, etc. Hopefully all will be well. Will it be alright to let this go until after the first start and warmup?

    ArKay,

    It should be ok;

    The PCM/ECM uses CASE relearn "error" data for misfire detection;
    if the error data is not correct, the motor should still run.

    Thanks Joe. One less thing to stress about now.
