If it’s any use, when I used to produce controllers for production cars we used to start (from key on), with a conservative knock setting and then trim towards knock and back off when it arose. After that there was a very slow dithering into and away from knock to get the best performance with envir...
Pleased you have a potential cure. If the knock sensor was isolation mounted they Ecu would drive the ignition harder and harder into knock, even it it is knocking. What octane fuel did you use? Higher octane gives less knock.

At high rpm you want the air fuel mixture to be right, running lean is hotter and not good. Other than air, crankcase gases are predominantly unburnt hydrocarbons and combustion products from blowby, plus the more volatile oil fractions, so the Lambda sensor should adjust within acceptable limits t...
