Haldex Performance Controllers
REDEFINES TORQUE TRANSFER // PROACTIVE POWER DISTRIBUTION // MORE AGGRESSIVE HANDLING CHARACTERISTICS
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.
GEN 4 COMPETITION CONTROLLER
Applications: 0BR Couplings: VW Golf R / 0BY Couplings: Audi TTRS Quattro
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.
HPA Haldex 竞赛版四驱控制器
Golf R20 R36 Audi TTS/TTRS专用
早在2004年，HPA已经与 Haldex 的工程师们合作发展 Haldex ECU、成为第一代的 HPA Haldex 竞赛版的原型。跟其他 Haldex 不同的地方是、HPA 的竞赛版能在刹车情况下保持后轮的牵引力、这功能可以满足要求最高的车主甚至符合在赛车场上的需要。
HPA跟Haldex再度合作，研发出 HPA 专利的 Haldex 四代竞赛版。除了秉承了一代Haldex 竞赛版的优良特性外、还加上两项跟普通 Haldex 4代不同的特点：在类似4代的赛车模式下、当刹车时轮上因为刹车的扭力得到反馈到 AWD 离合片上，使换低挡减速的性能得以大大提升，另外、HPA Haldex 竞赛版的控制器在用左脚刹车时不会把离合器分离、这使得在赛道上惯用左脚刹车的车手一个大惊喜。
HPA第4代竞赛版 Haldex 控制器并没有（不需要）提供可以切换的模式、它只提供前50后50的牵引力、以及上述描述特点、令 HPA Haldex 4代竞赛版成为顶尖车手为取得最佳四驱性能的不二之选。
