First, do you really think BMW wants to see its ECUs broken into, and reprogrammed? Why do they, along with all mfrs, put in place very strong ECU locks to prevent this? Leaving aside whether a BMW dealer will actually take any notice of a request not to update, the reality in many cases, owners will actually want the update.

Don't get me wrong, I want to be able to install a tune. We all know the factory tunes are conservative. But it must be simple to do initially, and to reapply after a software update. That pretty much means either via the OBD, or through a simple piggyback that covers all tuning parameters, eg, fueling as well as boost.

I'm not optimism I'll see this during my ownership of the M135i. The security is getting harder and harder to crack, and it's starting to take longer than my ownership lifecycle. Just sayin'
