You choose the appropriate mode yourself:

1. Sport mode: Flap(s) permanently open -> sound volume increased
2. Comfort mode: Flap(s) permanently closed -> sound volume reduced
3. Factory mode: Control of the flap(s) as before in the stock configuration
4. Freestyle mode: Flap(s) 50% open for individual sound and volume configuration

Additional features:

You later decide for yourself whether the control unit remembers the last set mode, which is then automatically reactivated the next time the engine is started or whether, for example, a certain mode should always be activated when starting the engine, regardless of the last setting.

In addition, the control unit has a special function with which the mechanical stops of the exhaust flaps are retrained. This is necessary, for example when replacing an exhaust flap or when an exhaust flap is to be installed in another exhaust system so that it then functions correctly.

DELUXE-control with the following advantage: The control system includes flap diagnostics. This means that our control system monitors the exhaust flap(s) permanently and detects if there is a malfunction (e.g. flap is jammed, sluggish, does not reach end position, ...) and reports this to the vehicle.

Please note: In the motor software of the Competition models with 375kW or OPF, there may be an error memory entry in the engine control unit in isolated cases when the OPF is regenerated and the flaps are permanently open.
