I recieved my knock sensor today and my 58 fuel reg(thanks jerry) i plugged the knock sensor where it looks like it goes and the regulator up, added the rxp ignition. it ran great. 70.4gps. it was close to a hundred today so i think it slowed it down a little because it ran 72.3 two days ago before these recent mods. any way my question is what does the knock sensor do and i want to make sure i plugged it up in the right plae?
