False Knock?

[oztracktuning]

I am chasing some knock at around my stall speed that doesnt want to go away. I wonder if it a vibration through the car from the big changes in force when the car hit stall speed on kickdown etc. The knock doesnt seem to impact on the afrs??

Here are some pics
I have not that much timing in the trigger areas - yet up to 28 deg at high rpm without issue.

Hmm, looks like just single instances rather than a consistent rattle. There was discussion on this before and I think Delco suggested that if you arnt seeing a saw tooth effect from sustained knock then it might just be a one off occurrance.
From my investigations if you arnt hearing any knock, you are getting the odd spike here and there and none under sustained load, then forget about it.
Id be interested to see what others have to say these days on the topic.

If you are suspect of detonation, you could just make the timing like 15 degrees in that area and see if it still shows KR.
