No knock at all, I enable DFCO, COT, and drop the Low octaine spark 3 deg across the board (it was matching the high octaine), and now under low (30%ish) throttle I get some good knock. Any clue what could have caused this?

well it foes look like a fals knock !
but to confirm it ,,
you need to lower timing in the know areas ( pull 2 degrees ) and see whats happened
if it didnt work ,, get a high octain fuel ( 100 will be good ) unledded , and use few gallons ,, have a run and scan ,, if u still have knock with that AFR ,, i guess its a false kr ,,, if you didnt have have any kr ,, that means its real kr ,,
that might help
