If the vehicle has selectable driving profiles, the exhaust valve can be controlled through this function. For vehicles without selectable driving profiles, a supplied switch can be used. The switch’s LED indicates the valve position: when the light is off, the valve is open; when it is on, the valve is closed.
The Bull-X Tronic control unit provides two operating modes:
- Sport (Dynamic, Race): the valve remains open while driving within the limits permitted by the ECE regulations, but is always closed when stationary.
- Comfort: the valve remains closed, opening while driving within the permitted ECE range from 75% throttle opening.
Road use: ECE approval applies only when the Bull-X Tronic control unit with ECE approval is selected and an approved EG catalytic converter is used. All other control and/or catalytic-converter combinations are intended for track use only.
Suitable for: Ford Mustang VI (LAE) / VI (S550).
