rotorque Posted December 30, 2005 Share Posted December 30, 2005 Hi guys, What sort of signal is given by the knock sensor....? Is it a constant voltage? How does the signal change when it senses a ping? Can I trick the ECU into thinking there is a knock sensor connected....(I know its not advised etc, just need the info) Thanks in advance Paul Quote Link to comment Share on other sites More sharing options...
nipper Posted December 30, 2005 Share Posted December 30, 2005 no no and no it is a peizo electric signal. an AC pattern generated by a quartz crystal, that is very very low voltage. The knock sensor is your freind .. why do you want to futz with it? nipper Quote Link to comment Share on other sites More sharing options...
Log1call Posted December 30, 2005 Share Posted December 30, 2005 yes, nippers right, it produces an AC voltage, you need it in circuit and the car runs better with it on! If it's giving trouble it may have been over tightened, the car may have the wrong/faulty fuel or the heads may have been planned too much.

rotorque Posted December 31, 2005 Author Share Posted December 31, 2005 Thanks guys..... I wanted to run my engine without the sensor due to the fact that I don't actually have a sensor......yet. I have just finished rebuilding a wrecked engine and am still in the process of sourceing all the sensors.... I'm a bit over it, so am getting a little over eager. I will take a chill pill and source a sensor. Cheers Quote Link to comment Share on other sites More sharing options...
Gene J Posted January 1, 2006 Share Posted January 1, 2006 Hi guys, Can I trick the ECU into thinking there is a knock sensor connected....(I know its not advised etc, just need the info) If you leave it disconnected the ECU will pull timing and set a CEL. You will get poor milage and power but it will run. Quote Link to comment Share on other sites More sharing options...
