Scott Posted October 18, 2012 Report Share Posted October 18, 2012 Hi Mike, Our G1 guru is away today. According to the information I can find your ECU is not PC tunable. For it to be the PC tunable model it needs to have WRXROAD followed by Q, R, S or T. It can be upgraded to be PC tunable. The ECU will need a chip upgrade and then you will need to use the SerialLink product to communicate with the ECU. A better option may be to upgrade to the G4 plug-in ECU for your model. I will have our G1 guru have a read over this thread upon our return and correct me if need be. Cheers, Scott.
