Hello! so i purchased a tuned 2008 g37 with a 2012 motor and 2011+ ecu swapped into it for easier tunning capability. The previous owner had lost the keys and I've called 2 locksmiths to make a key for the car but they cant. something along the lines of the ecu cant recognize the key or bcm not communicating with the ecu. I've taken the car to a vq shop but their lack of professionalism has made me want to take matters into my own hands because I was told the issue would be diagnosed in 1 day and its been 22 days and they haven't even preformed much work to the car at all. I do car work myself all the time but I didn't feel like dabbling into electronic problems and thought that they would be able to finish the car faster but i was wrong. what should I look into? I can order a whole new ecu, bcm, igniton system, key fob package for it which i believe will work. But at the same time I don't want to lose the tune on the current ecu. Heres a photo of the errors. and keep in mind the car worked perfectly well before the key was lost. THANK YOU! I REALLY NEED THE HELP!
