The newest generation of 4Motion equipped cars use Haldex's fourth generation of AWD systems. The Gen.4 Race 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
HPA Motorsports is proud to exclusively offer our "Stealth" Gen.4 Sport Haldex controller. Identical in appearance to your stock controller, you can now enjoy all the benefits of this performance component without jeopardizing your powertrain warranty. The Stealth controller is undetectable by your dealership; both visually as well as through a scan of your Haldex AWD drive system.
By default, the controller is designed to be in Race mode which completely transforms the handling characteristics of your AWD car by providing faster reaction time to vehicle inputs in the AWD communication system, increasing torque transfer to the rear axle, and giving more rear wheel bias.
With the installation of a specially engineered wiring harness and switch, or wireless receiver with remote, you can have instant access to all three of the programs built in to the controller; Stock, Race, and Eco.
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.
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 AWD drive is not a high priority.
