patb Posted November 9, 2016 Report Share Posted November 9, 2016 Ive just bought a Link G4 second hand for my R33 GTR. I just have the Ecu. I know i need a map sensor to make it complete but is there anything else i need? Quote Link to comment Share on other sites More sharing options...
Scott Posted November 10, 2016 Report Share Posted November 10, 2016 Hi,Do you have the plug-in ECU for the GTR? If yes this would normally have an onboard MAP sensor already.If the engine doesn't have an IAT sensor fitted I would recommend adding one.A wideband O2 sensor and controller would be useful too, particularly if you are going to tune the ECU yourself.Scott Quote Link to comment Share on other sites More sharing options...

Scott Posted December 1, 2016 Report Share Posted December 1, 2016 You will want a hose with a 3 mm internal diameter. Often the hose used is made from silicone.Scott Quote Link to comment Share on other sites More sharing options...
