The knock level is always at 30-70% when driving. I adjusted the sensitivity table with higher ...

I attached my most recent tune and log. I again lower the ignition timing, I think it helped a little but the knock control still went up high (car is running 94 Octane btw). And knock retard again pulling timing.

Noise and vibrations from the exhaust. Most likely you need to adjust the sensitivity of the knock sensor in low load.


I did lower the sensitivity by a bit, I dont want to go too far as I still want it to catch real knock.
One interesting point is that knock always happen when the car is warm ...
