> I am going to test knock sensors on my Corvair. I have never fooled with knock sensors. I did read up on them several years ago. What struck me was the assertion that a knock sensor from one model of engine can't be expected to work properly on a different engine. It was like they had to change the knock sensor functionality when they made possibly even minor changes to the engine. The natural frequency of each engine type (do they REALLY have a natural frequency?) is such that detonation just doesn't sound the same from engine to engine.
I no longer depend on my memory... So I suggest doing some research. Very interesting topic too. GeoB
