Some of the Ford PCMs don't have a knock retard PID to log which isn't helpful. In this instance I'd suggest you use audio knock detection equipment. The other issue I've struck with some of the Ford PCMs is that the update rate in the scanner for certain PIDs is too slow to be useful. It seems you're only getting updates for your lambda target and actual lambda around 2 times per second which isn't enough. I'd suggest fitting a wideband and bringing this into the scanner.

Thanks Andre for your help but the knock sensor was reading before
