Paora Smith Posted September 15, 2014 Report Share Posted September 15, 2014 Hi guys, I have a g3 that I updated to g4 software. Link copied the tune for me. Car starts and runs but as soon as I bring the engine up to 1500rpm the ecu disconnects and the fuel pump keeps running. Any idea why this might be? Tune was running fine but I upgraded to g4 for vvti control. Tried new earth cables, plugs, unplugged alternator in case it was faulty. Checked all wiring connections etc. No faults come up when it happens. I can attach the tune once I am home tonight. The engine is exactly the same as previous. I am upgrading the cams and coils this week. Also I cannot roll back to g3 software for some reason had Simon talk me through it but would not work so that option won't work unfortunately.
