Exhaust valve control
If the vehicle has drive profile selection, the valve can be controlled through this function. On vehicles without drive profile selection, control is possible using the supplied button. The button’s LED indicates the valve status: when the light is off, the valve is open; when it is on, the valve is closed.
The Bull-X Tronic control unit with ECE approval provides two operating modes:
- Sport (Dynamic, Race): while driving, the valve is always open within the limits of the ECE regulations; when stationary, it is always closed.
- Comfort: the valve remains closed, but opens while driving within the limits of the ECE regulations once the throttle is 75% open.
Versions without ECE approval offer Sport (Dynamic, Race) and Comfort modes; in Comfort mode, the valve opens at 75% throttle opening.
Road use: ECE approval applies only when the Bull-X Tronic control unit with ECE approval and an EG-approved catalytic converter are selected. This combination is intended for use on public roads. Versions with a switch, remote control or Bull-X Tronic “Race” CAN-bus control unit, as well as other catalytic converter combinations, are intended for track use only.
Suitable for: Audi RSQ3 I (8U).
