Steve Bull Posted April 6, 2020 Report Share Posted April 6, 2020 Trying to get my xtreme to register vehicle speed. The gearbox sensor is a two wire that produces an AC current which i dont think the ecu can read. Well it doesn't seem to regardless of pullup or rising/falling. Next tried a hall effect 3 wire which switches the 12v supply to 0.5v signal. Again this doesn't seem to work, or the ecu is recognising it. Does the voltage have to be a lot higher for the ECU to see it. What the best solution Thanks Quote Link to comment Share on other sites More sharing options...
Simon Posted April 6, 2020 Report Share Posted April 6, 2020 Switching point on the Di inputs is 1.5V so as long as either sensor is switching above and then below 1.5V it should pick the signal up. Quote Link to comment Share on other sites More sharing options...
Steve Bull Posted April 7, 2020 Author Report Share Posted April 7, 2020 Thanks ill look for a different way to do it. Saying that though instructions for the VSS were all in Chinese. A Google and the black wire isn't the earth but the load. While the blue, normally the signal, is the earth so it may work once rewired.
