What kinds of things do you guys change when you detect a knock? Mine is coming in at wot and is being retarded a couple degrees. I am running 92 octane, and my base timing is 8 degrees. Thanks.

Adding some fuel just BEFORE the onset of knock can often help.

Remember heat builds up in a chamber, and at times can be hard to cool it some as you go to WOT. Somestimes just a little added pump shot of AE can help

So by adding fuel before the onset of knock, are you talking like a couple hundred RPM or so? Thanks.
