E38 Knock Retard?
Which knock retard value PID should I be logging? GM.KR, or GM.KNKRET? GM.KNKRET usually shows some value in the MAX column, but I never see any of its other values change. GM.KR seems to always say 0 in all the columns. My car is a 2011 Camaro SS LS3. It has cam, headers, high flow cats, a cold air intake, pulley and a tune. I had it dynoed yesterday, and it was about 30 low on HP and TQ (430RWHP 400RWTQ) from what everyone else is getting with the same mods I have. It was about 70*F outside with low humidity. I thought if anything I would get higher numbers in those conditions. It may have just been that particular dyno I guess. My AFR is just about dead on 12.8, and the tuner running the dyno said to look at my timing. I attached a quick log from this morning. Thanks.
