Stefan1436215452 Posted March 6, 2014 Report Share Posted March 6, 2014 Hello, I found a link G3 plugin for V7-9 WRX and I was wondering if the ECU can accept additional external sensors? Will I be able to fit an IAT & a MAP sensors in addition to the standard sensors on my 2002 WRX? If so, how do I do that? I found some articles that maybe relevant but the links dont work.

Simon Posted March 7, 2014 Report Share Posted March 7, 2014 http://www.linkecu.com/support/documentation/g2-g3-engine-management-documentation/WRXLinkG3 This will help. There is provision for IAT and we would use factory map sensor but this can be changed to other options if more boost is required. Quote Link to comment Share on other sites More sharing options...
Stefan1436215452 Posted March 9, 2014 Author Report Share Posted March 9, 2014 Simon, Im stuck and I could use some help please. I purchased the link board today and it is a WRXLink G3 Subaru V7-9 plugin PCBV1.7. I read the manual you linked above, downloaded the software and installed it including the drivers on my Windows Xp partition. The com port is automatically assigned and I can select it from pclink 3.4 connection settings window. I plug the ecu into my car, I set the key to on position and try to connect to the ecu but I get an connection error message so I did the same on the windows 8 partition and I had no luck their either. I changed the the ECU from Option 2 to option 1 using the jumpers and tried again but no go. I cannot not even tell whether the board is powering up. I hope I havent spent all that money on a dud unit. The unit came with the usb cable, display link connector and the xs-connector which was a nice surprise. Regardless of which jumper setting is selected the fuel pump does not prime but I can crank the engine. What can I do to help diagnose the problem? Is their away to bench test it? Any help is appreciated. Regards, Stefan Quote Link to comment Share on other sites More sharing options...
Stefan1436215452 Posted March 9, 2014 Author Report Share Posted March 9, 2014 I should give you some information about my car. Its a 2002 WRX which has a Denso, 5K 22611AH570, 112200-4420 12V. I couldnt tell you whether it is a Japanese import or an Australian delivered vehicle. All factory sensors. Quote Link to comment Share on other sites More sharing options...
Simon Posted March 10, 2014 Report Share Posted March 10, 2014 I suspect that the ECU is not powering up. The thing to look for on the board will be a green LED this should light once the ECU is powered up. IF the light is not coming on then we need to check the power supplies to the ECU.
