speeddm Posted September 18, 2014 Report Share Posted September 18, 2014 So here is goes . I have a V44 plug in for a GTR. I had communication for a while was going through calibration steps. Turned ignition off and now I have no connectivity. Went through all the FIFO and connection fix steps. Uninstalled software and USB drivers re installed older version nothing. Tested using a different PC and it doesn't recognize a USB has been plugged in at all. Any Ideas???? Thanks. Dave Quote Link to comment Share on other sites More sharing options...
Simon Posted September 18, 2014 Report Share Posted September 18, 2014 Check the plug on the short lead from the topboard is fully seated at the ECU end. I have seen cases where a terminal has pulled back out enough to loose contact. Quote Link to comment Share on other sites More sharing options...
