In 2004, HPA collaborated with the engineers at Haldex to develop an exclusive Competition variant of the Gen.1 Haldex ECU. Unlike any existing controller, HPA’s Competition unit retained rear driveline engagement under braking; a key advantage in motorsports, and for driving enthusiasts. Once again, we worked with the team at Haldex to develop this exclusive Gen.4 Competition version, and bring this potent technology back to the market. The HPA Gen.4 Competition Controller is calibrated similar to the "Race mode" setting used in the standard Gen.4 Performance Controllers, but has the additional feature of increasing the clutch torque when braking. By doing so, wheel brake torque is now transferred rearwards through the AWD clutch, offering a far more aggressive deceleration capability. Additionally, the Competition controller will support left foot braking without disengaging the 4-motion clutch while out on the track.

This Gen.4 Competition unit does not offer the selectable modes offered in our standard Gen.4 Haldex Performance Controllers (Stock, Race, and Eco, for reference), and therefore no extra switch or remote is required. The HPA Competition controller is the ultimate tuner solution for your Gen.4 Haldex-equipped car.
