This risk comes with the territory, I guess.
I have a Bosch knock sensor on mine and cannot get reliable readings from it since this motor is already noisy (valve train, air cooled). So the threshold to start counter-measures is kind of a guess. Too low, and you loose performance - too high and loose pistons.
