To my understanding, if you patch the ECU/DME and then use BM3 to tune it.
The moment you decide to remove/lock the ECU/DME you need to patch the ECU/DME next time you want to tune it?
Im really hoping for a better solution then to remove the ECU/DME unit.
This won't be a big problem maybe but time consuming each time.
Or is this a good thing? For example when you need to service the car BMW shouldn't notice anything if they ain't starting to poke around
