Thanks again.
Ive updated the ECU but still no CAN settings? When connected to the ECU i only get
Disconnect ECU
ECU log file download
Store ECU
Restore to factory settings
Setup password
Unlock password
However when im disconnected i get much more including CAN configuration but when i click it i then i get a error message saying "CAN is not supported by this firmware version, upgrade firmware and try again"
Maybe i cant open the G4 CAN? Or is there a different setting for the RS232?
