Thanks Graham! My ALDL -> USB cable didn?t arrive yesterday like it was supposed to, so unfortunately no data from today. The AFR stayed clean from the shop?s sensor at least. I believe the plug wires are new-ish but not sure on the plugs. Once I can datalog I?ll do some highway pulls and check for knock counts.

Graham,

Was it the puffs of smoke that gave it away for knock? My experience is that if there is detonation it likely occurs between 4500-5500rpm on a WOT pull.

Yes. The engine is most "Knock limited " around peak torque typically.
