Knock retard?

[Gregs]

I'm getting a bit of knock retard logged and not sure what is going on. RPMs are not high, AFR looks good, and timing doesn't look out of whack. I've attached the latest log file, and the KRs are showing up between 6570 and 6620. It's not much, 1.1 degrees, but it concerns me anyway.

Any ideas?

I don't see any knock in that frame range. The only knock I see is at frame 9896 and its not concerning. Its only 1.1* and it doesn't have a sawtooth pattern=false knock.
