You will need to listen to Terry, send LOGS and he will sort the car out very quickly. For this you will need a USB cable as per the info on N54tech forum and he will sort your car out very quickly. For instance what software, firmware and interface are you running. There are different versions for N55 and you also have Stage 1 and now Stage 2 out which you have to upload to the PC which you are using with the usb cable to adjust various parameters on the car. If you are not comfortable with adjusting manually upload the latest firmware and interface and simply run the car on the map Terry recommends after you have sent LOGS.:blab:
