HPA Motorsports - 0BS / 0AY GEN 4 Switchable Haldex Controller inc Harness & Switch
Take full control of your GEN 4 Haldex equipped car with three selectable driving modes: Stock, Race, and Eco!
While sharing the OE and RACE modes of the Generation 2 controller, the Generation 4 controller replaces SPORT mode with ECO mode.
Eco mode was developed for increased fuel efficiency. Its purpose is to reduce the torque transfer from front to rear during normal highway driving (coasting), but will immediately engage the system if a wheel starts to slip to prevent decreased traction situations. This mode is recommended to be used when 4 wheel drive is not a high priority.
By default, the controller is designed to be in Race mode. With the installation of a wireless receiver and remote, you can have instant access to all three of the programs built into the controller; Stock, Race, and Eco.
