Easy installation:

The control unit arrives pre-assembled and pre-programmed including illustrated installation and operating instructions. Thus, the assembly is done easily and quickly in a short time. Per request the installation can also be carried out at our site.

Guaranteed compatibility:

The control unit integrates seamlessly into the vehicle electronics, is 100% compatible with the specified vehicle types and does not cause any errors in the vehicle electronics. Nothing has to be changed on the vehicle for installation. The device can be removed at any time without leaving any residue and is therefore also ideal for leasing vehicles. The device does not consume any quiescent current when switched off and thus does not affect the on-board electronics.

You choose the appropriate mode yourself:

1. Sport mode: Flap(s) permanently open with sporty and robust sound regardless of driving situation and vehicle settings
2. Comfort mode: Flap(s) permanently closed with discreetly restrained sound regardless of driving situation and vehicle settings
3. Serial mode: Control of the flap(s) as before in the series configuration, e.g. for service, etc.
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.
