ECMlink Cruise log. Getting some knock

[stroh]

I took a cruise log today. This is only about the 3rd time I have driven the car since the rebuild. I'm getting some knock around the 1100hz to 1400hz area. What should I do to fix this. I have run the mafcomp adjust tool but it doesnt seem to help. Any help is appreciated. Thanks

Yea I saw that at ~20% Throttle, I would try BPR7ES plugs with a .028 gap. That slight knock retard could also be bad gas. It looks random as I see no correlation with the O2 cycle or degrees of timing. You hit 30-33* before and it didn't knock. Could be vibration, phantom knock,etc...
