We all knew this was coming and BMW was pretty clever introducing lag and then making people want new software that will close the door on tunes. I would expect BMW to be releasing there tune they are using on the 745 before christamas now.
I don't think they can stop you from installing an ECU piggyback, but what's the problem if the new firmware detects them?
if you are operating the engine at a level beyond what it is set up for, then it's only fair that they are not responsible to cover it.
