    Re: I can't get misfire?

    Have you deleted the DTCs for the misfire?

    Many people with a large cam do, because the cam will cause false misfires.

    I would check that, 300 is the one that was turned off on mine.

    killer01ws6,
    where can I find the (300) that you are talking about. is it the 300-Engine Misfire Detected? if it is the one? mine is set to ErrorMode>3-no Error Reported.
    And the SES Enabled >Off
    does this help

    Yes that is the one he's talking about. Has somebody tuned your car before or did it come that way from the factory?

    Well,
    The way my car is stock is:
    SES Enable ON
    Error Mode One - MIL in second error

    I used to have a P0300 come on with my car every once in a while so I edited:
    Edit->Engine Diagnostics->Misfire->Max time between events->low rpm and changed all values to 32000.

    Try that and see what happens.

    Re: I can't get misfire?

    If that doesn't work then you most likely have a pretty stout cam so then try your idea of:
    Enable ON
    Error Mode Three - No DTC reported
