Hi Terry,

To revive an old thread, I also have installed this on a car with an OPF/GFP (2020 M4).

I had the same issue as BomberF33 - no matter what setting (open/closed/OEM) the flaps remained closed. Even stranger, once removing the module, the flaps remained closed regardless of engine mode until I had shutoff the car and come back later in the day.

Playing around yesterday evening I found that it might be related to the ASD settings: I had enabled option 1 (ASD mute when flaps open), but after disabling this, the flaps seem to work as intended given the basic settings (open/close/OEM).

Will dig a little bit more.
