mark brown Posted May 7, 2011 Report Share Posted May 7, 2011 Hi, I have a lemg3 and have connected the speed output wire from the speedometer cluster to the lemg3 d1 terminal. It had the calibration preset on the base map but for some reason the ecu wont read the speed? The speed signal wire from what I understand when I traced out a spare wiring loom is on dash plug 1 (smaller of the 3 plugs) the yellow wire with green tracer. I'm sure this is the correct wire as I've double checked it after the ecu did not detect the speed. I have attached the pcl file in case there is something wrong in the settings. Thanks for the help with my other posts also. cheers, Mark 012-rb30det-wideband-ross-tune.pcl Quote Link to comment Share on other sites More sharing options...
Simon Posted May 13, 2011 Report Share Posted May 13, 2011 Hi Mark. You will need to check the signal at the ECU. Try setting the DI to a frequency input to see if you get any reading. It could also be worth trying an external pull up on the speed input about a 1K to 12V would do the trick. Quote Link to comment Share on other sites More sharing options...
