I found that for the writing of this ECU is after the car is running and you select the change to remember autostart setting, I had to turn the engine off for the ECU to code. Otherwise I got an error message unable to write ECU

For the adapter, the OBDLink LX for G series is what I got. The MX and MX+ are a waste of money for the BMW as they have features for Ford and GM. If you have a Ford or GM then those would be useful. Otherwise, the added features wont do anything for the BMW
