Fairly sure the USA guys that have been disassembling the CSL software have discovered a specific VE map related to the flap opening and closing and yes it does affect the tune of the car.

Btw for those who are running without the flap. You can unplug the flap-motor and store it away. It doesn't give you an error in the dash, nor does it raise an error code. Incase somebody didn't know already.
