Brandon Posted September 10, 2017 Report Share Posted September 10, 2017 hi I'm new to the forum and new to tuning so please go easy on me my friend has the red G4+ extreme ecu he's fitted the Toyota 1uzfe engine to his Nissan 200sx s13, the Ecu and the engine was bought as a package which was fitted to another car previously and as far as we are aware that was running fine, we are using the pc link tuning software. We are having issues getting the trigger setting (1uzfe) to store in the Ecu. If we select the setting and store it, it stores successfully engine cranks and fires and runs a dream however when the ignition is switched off and back on again the engine will not restart unless we restore the trigger setting in the Ecu then again it will start successfully. I've checked all the lives and the earths supplying the Ecu and everything's as it should be. Beginning to think maybe an internal issue within the Ecu may be the cause. If anyone can help with this issue it will be greatly appreciated i will do my best to answer any questions thank you Quote Link to comment Share on other sites More sharing options...
Ducie54 Posted September 10, 2017 Report Share Posted September 10, 2017 Are you currently running the latest firmware? Also make sure you press F4 to store to the ECU. Quote Link to comment Share on other sites More sharing options...
Brandon Posted September 10, 2017 Author Report Share Posted September 10, 2017 hi thanks for the reply, no I'm not completely sure what software the ECU's using but it definitely hasn't been updated in the past two years (i will try to check what software) and yes we are storing it to the ECU we've tried saving it to the computer but still haven't had any luck thanks Quote Link to comment Share on other sites More sharing options...
Simon Posted September 10, 2017 Report Share Posted September 10, 2017 Check that ECU hold or engine kill are not active when cranking and also the ECU has been unlocked. Quote Link to comment Share on other sites More sharing options...
