ASR flap control RX1 for BMW – full control over the sound

The ASR flap control RX1 It was specifically developed for BMW vehicles with an electric exhaust flap (type BE1). It is compatible with the following models: 330i and 340i (F30/F31/G20/G21) and allows you to manually control the exhaust flaps at any time using a remote control.

• True series mode:
  The system can be completely deactivated and remains in its original state even after the vehicle is started. Perfect for workshops, service centers, or vehicle inspections.

• Freely programmable start mode:
  Specify which mode should be active at startup – or let the last used mode be restored automatically.

Start mode – flexibly customizable

The start mode determines how the exhaust valve control reacts when the ignition is switched on. Whether the last state or a predefined mode – the setting is easily adjusted via the remote control. The system automatically confirms successful programming with five opening/closing movements of the valve.

Installation is plug and play, directly at the exhaust flaps. For optimal signal strength, we recommend placement in the trunk. All cables are sufficiently long and can be routed in a weatherproof manner.
