Dinan is not set and forget as you say as it is a flash at a Dinan dealer, which means that you have no control of the tune install. If the car gets a BMW update, the Dinan tune will be over-written. Furthermore, you are limited to a single map. Cobb you can have multiple maps and quickly swap maps or go back to stock from your own garage.

I believe that the Dinan flash works just like a BMW PPK in that its linked to your VIN. So you really do not have to worry about it getting it(the Dina tune) over written when a bmw dealer does a sw update.
