So I have been hunting for this knock event, and finally managed to catch it in action. The picture shows everything you need to know:

38 % throttle
11.42 psi boost
3 COUNTS of KNOCK
a low 2,6xx RPM
160 load
7 degrees timing (not logged)

should I care given the load and throttle % ?
This happens just driving to work in the morning driving chill...

I get the same ****, occasionally at 6,8 once a 10! Then I'll log a few WOT pulls, 0 knock, no clue.

 

I am not worried about WOT. If I had 3 counts of knock reliably for WOT I would address it until it was gone. WOT would be totally different load cells.

This however is only 38% throttle. So not much power. But still it is a 160 load, which isn't nothing; and it will see this region day after day driving normal. So I am concerned that I need to get rid of this (which I have not been able to yet), even though it is low rpm and low throttle.

Is this truly an ignore situation ?

I look at it this way: 11.5 psi is more than some OEM turbo cars run, and here I am knocking every day at that level (160 load).

I'm having 9-13° advance in this area, occasionally some knock 1, 2 maybe.
I ignore knock up to count 3 in partial load (and actually everywhere else as well)
What you could try is a bit more ignition Dwell, so more energy to the spark plugs in this area, http://www.evoxforums.com/forums/sho...d.php?t=262282.
