Two questions Twinz:
- Is the unit locked to the car as long as the software is installed to the car? Can you sell it without uninstalling?
- Is the mod detectable by Motorplan?
Trust that needs to be clearified for interested parties
Hi Rolf, I think Twinz covered the the 1st point.
Is it detectable by motorplan, I would say no for normal servicing/etc. It does put some form of encryption on the DME so BMW can't do proper diagnostics, but one can uninstall the Cobb to prevent this. As always my golden rule applies. If you as the owner are not comfortable, then leave it stock.

OK that far I can follow.....
Now to the crucial point:
- the OBD port is handled by the ECU's processor which allows access to the flash and coordinates addressing of the maps (else one could not just change a single map but would always have to flash the whole software).
- knowing this it must be noticed that all read and write operations are monitored and logged in the processors internal e²prom.
- this e²prom is not a separate chip
- this e²prom can not be programmed via OBD
In my humble understanding of the materia, BMW will always be able to detect if boost and rpm have been fiddled with should they suspect such thing and connect their system to the car to transmit data to their HQ
Am I wrong here?
Yes they may well be able to see if the flash counter has been incremented (not confirmed yet, but may be the case). No they cannot ever see that boost has been raised unless they drive & log the boost. And they don't have equipment to do that. All their equipment does static diagnosis.
