Re: Knock Retard only when car is Warm/hot?

well, I checked and double checked everything, and everything was ok. I just zeroed out the KR vs MAP table, since the KR vs RPM is still active, im not worried. The car runs great now. I am just working on AFR now, and timing. The car has stock timing tables. What should I go after next, AFR or timing? My WB is in the location of where the o2 would go on the end of the driverside header. Im getting a AFR of 15.2-15.4 at the moment, should I go leaner?

UPDATE: I went in the KR vs. MAP table, and restored all the original values. I went into the timing table and uped the idle timing from 22° to 27-30°, and all the KR is gone! This also took away my off the line hesitation/bog..
