Hi

Well on the stock ECU 26 would be a very serious amount of knock, but I understand that you can't compare the knock count on a PFC to the stock ECU.

I also just leard from a thread on here that the PFC has no knock control, though it will record knock, it won't back off the timing or add fuel like the stock ECU, so you might want to find out why your seeing knock pretty quick.

would guess the peak noise to be somewhere between 4500-5500 rpm about where peak torque is.

Knock can happen any where, things like timing, AFR and boost level affect it most. But thats on the stock ECU, the PFC may use a different method to calculate knock.
