You can log all of the Spark Retard PIDs and know exactly
who's bugging. Otherwise you have only a list of suspects.
Of course there's also the possibility that it's some Advance
element that goes negative. Log 'em all.

8.0* of burst knock, zeroed out burst knock enable delta cyl air threshold vs rpm and burst knock retard vs rpm.... then got a little of KR like 1.5 in one cell.... this is just sitting in neutral and a few small revs
