Just wondering how everyone monitors knock retard. Do you ever look at it, or do you leave it to your tuner? Do you just look at OAR, or do you watch actual KR? Do you look at per cylinder, or the overall average? What device do you use - an OBD2 gauge (like Areoforce) or log scan or something else? I still learning how everyone tune their Fords. On my last car (GM), I'd watch KR. If I didn't see any, it was time for more timing or more boost. I don't see much discussion about KR here.
