[QUOTE="basspro302, post: 15879575, member: 171674"] Lots of people know how they work. Its a pizeo sensor that produces an a/c voltage when its vibrated. The ecm can be tuned to have a thresh hold for knock. So basically when they design the engine the will have all the known harmonics in place and they can see how the sensor is reacting to it and tune the pcm to only pick up real knock. That can go out the window with after markert parts changing the harmonics of the car. [/QUOTE]
