Last night, I logged a short run which recorded 3 instances of knock (see below).

I have checked the spark & VE tables & both seem ok. Could this be false knock?
Also, GM.DYNCYLAIR_DMA is showing a zero value apart from when knock occurs. How can this be, surely there will be a measure of air recorded when the engine is running.
PS: I have B6216 Burst Knock Retard set to zero.
Any ideas??
