Have you changed your knock settings at all?

 

1 and 2 counts of knock aren't lifting the head. Given the knock voltage, that probably isn't even real knock.

 

Well guys now I'm not getting any knock at all even with afrs dipping into the 10s.
My first reaction is I ended up tightening something down that was making noise when I last worked on the car but that wouldn't explain why I could lean out the mixture in the old days and have no problems and to why I was spewing coolant once per track weekend. Second reaction is that my failing coils were always the problem but for some reason when I first replaced them they didn't have a good connection or something.

Whole thing just raises more questions...
Thanks for the help though

I raised the multipliers a couple of points several months ago after coming to the conclusion that I was experiencing false knock.

 

If you are spewing coolant you are pressurizing the cooling system. When that happened to me, my head gasket was compromised just barely.
