Ferrari GTC 4 Lusso RX1 (U2-2-I) ASR exhaust flap control

Ferrari RX1 (U2-2-I) ASR Exhaust Valve Control

Full control over the sound of your Ferrari.
The ASR RX1 flap control allows you to manually control the exhaust flaps of your Ferrari GTC4 Lusso (and other models with a vacuum system and two switching valves, type U1-2) – independently of the Drive Select system.
This is how they decide herself, when your vehicle sounds sporty – and when it doesn't.

Product benefits

• Regardless of Drive Select: The vehicle sound no longer follows the selected driving profile – but your decision.

• True series mode: The module remains deactivated even after the vehicle starts – ideal for workshop, service or MOT visits.

• Freely programmable start mode: You can choose whether the vehicle starts with the flaps open or closed.

• No interference with the CAN bus: No impact on other control units or risk from software updates.

• Plug &Play Installation: Vehicle-specific original connectors enable easy, residue-free installation – without cable cutting or wire taps.

• Reversible: Removable without a trace at any time.

• Error-free: It works completely independently.

Start mode function

The start mode determines the state in which the system is activated when the ignition is switched on.
By default, the RX1 control remembers the last state, but can also be programmed to a fixed start mode – simply via a key combination on the handheld transmitter.

Confirmation: After successful programming, the flaps open and close five times.
