Yes. At first, I was getting a knock of 2.4 under acceleration. After about 10 minutes, it went down to 0.4

It's been about a week since I've had it and now for some reason I'm getting up to 1.4 knock retard. Maybe it's the weather... it has been hot and humid the past few days.

Its supposed to rain all week, so I guess I'll record a few datalogs with the bad/hot weather and with cooler temperatures when it clears up.

Anyone else have this knock retard concern?

have you recorded any data to prove how safe it is?
