Tech Spec

The Forbes Automotive OpenHaldex T4 Controller gives you full control over the Haldex 4Motion system. 4 switchable modes.

On 4motion cars, the Haldex system waits until it detects ‘slip’ from the front wheels at which point it engages the clutch-pack within the Haldex unit to drive the rear wheels.  On high performance cars, it may be advantageous to force specific modes to suit the driving style required at the time. The OpenHaldex T4 controller is based on a Teensy 4.0 and is positioned between the ECU and the existing Gen1 Haldex module.  It is Bluetooth enabled and can be controlled with push buttons on the device, an application on Android based phones (iOS coming soon) as well as a remote Bluetooth screen*.

The OpenHaldex module takes the existing CAN-BUS signals coming from the ECU to the OEM Haldex module and adjusts them to suit the required mode. There is a
standalone mode which means that the OpenHaldex module can be used on conversions
or cars without working CAN-BUS.  This will mimic OEM CAN-BUS signals to the Haldex pump to allow it to operate as if there was an original ECU in place.

Modes available:

  • Stock (*if provided with OEM CAN signals)
  • FWD
  • 50/50
  • Custom (*if provided with OEM CAN signals)

An optional Plug & Play harness is available. This allows the utilisation of the OEM plugs which means the module can be removed at any time! Click here for more information.
