A word about knock. You dont see knock you see knock retard. usually as in total knock retard. If u log all the cylinders u can see how much timing is pulled per cylinder. It may be 2 on one cylinder and none on the rest. Might see .5 pulled on all cylinders. The ecu is saveing the engine by pulling timing to where knock stops,( if sensors are set correctly).
Any car that has a procharger will need sensors adjusted period. I have seen knock retard a bunch of times on 13 14 pds no damage caint see it on the plugs and car still running strong at over 700 now I guessamate. In fact with good settings u can run right up to the edge of knock. My stock coop 2019 used to get up to 6 or 7 deg knock retard brand new no mods on shell 93. So thats what I think

I hope one of you guys gets a hold of log and can share your findings. I need to believe this was an octane starvation event.
