You will start to see ECU tunes for more BMW cars as a result of this development.

On the topic of Dinan, they make fantastic, well engineered products but don't have engineering support from BMW like you imply. If they had the factory support you suggest, they would have developed ECU tunes long ago for newer models but chose to go the piggyback route instead. Outside of their racing efforts, Dinan has a warranty relationship with BMW.
Yes, you are completely correct that BMW does not offer any engineering to Dinan, or for that matter, anyone outside the BMW family. That is my mistake for implying that fact here. Dinan reverse-tuned their ECU tunes (I had a 550i with their Stage 2 flash tune) and provides ECU flashes, as well as piggy-back where they have not reverse-tuned the ECU. The last article I read about most of their piggy-backs was that most read over 175 inputs and made the modifications to the stock ECU. That's more tuning than most.

I am not even sure you could call the warranty a relationship between Dinan and BMW, other than they might get better parts pricing and shop rates than someone off the street when an engine goes south within the OEM warranty period.
