    Well when I did that procedure twice, I still have KR of about 9.9. I don't think I did much to decrease KR at all. Does this confirm that it's false KR? Should I take the valve covers off and see if I can find anything wrong?

    Here's what my high octane table looks like:




    The part it dips down sharply is where a lot of the changes were made even though you can see where the selection is. I guess that's what I was talking about as far as the highlights not being in the same place.

    Id pull 3 degrees of timing out from .50-.90 between 2500-6500 rpms. These motors dont need that kind of timing to make power so no need dancing on the edge of detonation.

    First I would fill those cells with 15 degrees and confirm that you have no false knock. If there is no false knock drop the timing down.

    On the log chart, real knock looks like a sawtooth waveform.

    Give me some time, I'll play with this on mine.
