Haldex Performance Controllers

Redefines Torque Transfer // Proactive Power Distribution // More Aggressive Handling Characteristics


Haldex

The sophisticated Haldex based all wheel drive system used in the VW R32 and Audi TT Quattro monitors throttle input, ABS wheel speed sensors, steering angle, etc to anticipate and distribute torque transfer from the engine to the driveline.

Specially prepared Haldex control units are able to alter the time in which the system reacts to these dynamic changes and and how it reacts to them; creating more favourable or aggressive handling characteristics.

This upgrade increases torque transmission at acceleration providing consistent performance with increased over-steer. The torque-transmission is influenced by how fast you press the accelerator down. The Haldex system can transmit torque before the engine delivers torque. At greater speeds the torque will decrease enabling less over-steer and safer driving properties.

The advantages of this HPP upgrade are it’s ability to predict the onset of torque. This upgrade takes into account the TPS signal more so than the OEM software and therefore can proactively begin applying power to the RWD clutch packs before wheel spin begins. As power is increased, more power lock occurs in the RWD unit until full lock is achieved. To summarize, the new HPP is more aggressive with how it transfers power and does so much more proactively than the OEM system. This is ideal for autocross, road racing, and street driving as well as enhancements to poor weather driving.

With our new high tech AWD Superflow dyno, our techs were able illustrate the effective power transfer to the wheels in all three modes. The test vehicle was a turbo charged Mk5 R32, and the results are truly amazing! The graphs posted below illustrate just how much of the total wheel HP is being delivered to each of the front and rear wheels across these three modes.

Haldex

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.

Gen 4 Switchable Stock/Race/Eco Controller

Applications: 0BR Couplings Audi A3, S3, TT, TTS Quattro / 0BS Couplings: Passat 4-motion / 0AY Couplings: Tiguan / 0BY Couplings: Audi TTRS Quattro

Confirm which coupling your vehicle uses before ordering.

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 either a specially engineered wiring harness and switch or a wireless receiver and remote, you can have instant access to all three of the programs built into the controller; Stock, Race, and Eco.

Gen 2 Switchable Stock/Sport/Race Controller

Applications: Mk5 R32, Gen 2 Audi TT, Audi A3

Confirm which coupling your vehicle uses before ordering.

Most Mk5 based 4-motion equipped cars use Haldex's second generation of AWD systems. The Gen 2 Sport controller takes into account the TPS signal more so than the OEM software and therefore can proactively begin applying power to the RWD clutch packs before wheel spin begins, and as power is increased, more power lock occurs in the RWD unit until full lock is achieved. This product offers the following benefits:

  • Increases torque transmission at acceleration
  • Provides consistent performance with increased over-steer
  • Torque-transmission is influenced by how quickly you depress the accelerator
  • Transmits torque before the engine delivers torque
  • At greater speeds the torque will decrease enabling less over-steer and safer driving properties

Instead of the standard Blue Gen 2 controller, HPA Motorsports is proud to exclusively offer our "Stealth" Gen2 Sport Haldex controller. Identical in appearance to your stock controller, you can now enjoy all the benefits of this performance component without jeopardizing your power train warranty. The Stealth controller is undetectable by your dealership, both visually as well as through a scan of your Haldex all wheel drive system. By default, the controller is designed to be in Sport mode which transforms the handling characteristics of your AWD car by increasing torque transfer to the rear axle and giving more rear wheel bias.

With the installation of either a specially engineered wiring harness and switch or a wireless receiver and remote, you can have instant access to all three of the programs built into the controller; Stock, Sport, and Race.

As an enthusiastic driver you may not find yourself using Stock mode very often, but it will come in useful when loaning your car to an inexperienced driver, or when you are driving in slippery conditions and want to engage the conservative safety parameters set out by the factory.

Race mode will unleash further potential as it provides faster reaction time to vehicle inputs in the AWD communication system, and allows for even greater amounts of torque transfer to the rear axle.
