my s-afc 2 knock readings just went up to about 70 or 80 max, this somtimes goes up whenever i just tap on the gas pedal to get the car moving ,its weird, it hasnt done this since the tune a year ago. anyways i tried to reset the knock sensor to reaclibrate it, but it wont work? how do i properly recalibrate the knock sensor, or is there somthing else wrong with it?

dont you have to rev the engine/drive the car at a certain RPM level and then set it? you should do this at 2 different RPM ranges. that should work.
