2020Racing Posted November 1, 2020 Report Share Posted November 1, 2020 Hi guys, Trying to set up ECU for the first time. I have a G4+ in my race car and trying to set up a G4x in my road car 04 STI. The laptop recognises the USB is plugged in and also has the correct driver installed. But comes up with the error. Unable to connect to the ECU please check that the ECU is properly connected, the power is turned on and the correct COM port has been selected.

2020Racing Posted November 1, 2020 Author Report Share Posted November 1, 2020 Seems to be that the ECU has no power. No LED'S are lit up on the board with ignition on..but recognises the USB plugged in. Quote Link to comment Share on other sites More sharing options...
Adamw Posted November 1, 2020 Report Share Posted November 1, 2020 Assuming you have a WRX104X ecu? Did you try the jumpers in both the 2004 & 2005 positions? Quote Link to comment Share on other sites More sharing options...
