False knock?

[chevellejoe]

Just hooked up a powerlogger, recorded a pass to see were my car is at. Anyway I noticed my knock retard went to 1.8 deg between 3500 and 4800RPM in first. Second gear no issue and third i got off at 90mph but no issue as well. The Knock counts shows none thru the whole pass and o2s are at 862mv. Is this something to worry about?

Nothing to worry about. Knock in first and second gears is generally false. Third gear is the killer.

862 02's looks like its real rich if your 02 is good/reading correctly .
