Guest De Schmaydee Posted March 22, 2003 Share Posted March 22, 2003 .....i'm putting in another ecu and will no longer need the knock sensor.....but i was thinking of using it as a trigger for a detonation (audible) alarm.....but not really sure exactly how this thing works.....is it like a piezo-electric device?......s Quote Link to comment Share on other sites More sharing options...
80LS1T Posted March 24, 2003 Share Posted March 24, 2003 Why would you run a car with out the knock sensor? Isn't that an important sensor that you should have, if you can? Just curious! Guy Quote Link to comment Share on other sites More sharing options...

A. G. Olphart Posted March 24, 2003 Share Posted March 24, 2003 Most knock sensors are as you described (easier than spelling piezoelectric myself) and can be used to source a signal for an audible knock detection device. A much more preferable option (to me anyway) would be a smart digital ignition system which uses that signal to back a little timing out of the hot (detonating) cylinder.
