I know the sensors are sensitive, i have an aluminum floor pan and it was tapping before we spaced it out and that was causing false knock and the car was pulling timing. so it's possible a broken heat shield could cause a false knock reading, idk if it is the case or not, but definitely possible.

so far as fuel additives, ive never run them so i'm not sure if they could cause knock. i woudnt think so but i just dont know. I have used torco for knock protection when racing, but that upps the octane rating of the fuel just to help prevent it, nothing changes on the tune when i run that.
