Does it need engine vibration to do it? I have an F22a1, there's no place for a knock sensor, so I have it wired up and laying up above the ECU on it's little platform thing, with the proper plug in from the ECU, and wire coiled around the base and running to the ECU ground from grounding... So... should it be working, or does it need some vibration (I.E. to pass a magnet by a coil or something to make the electricity, if that's how it's constructed?)
