Stealthy, Switchable Gen 4 Haldex Controller with Stock, Race, and Eco modes for 0BR Couplings Audi A3, S3, TT, TTS Quattro, &VW Golf-R MK6. Haldex units that start with Part # 0AV use Gen 2, units with Part # 0BR use Gen 4
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.
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
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.
With a 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 graph posted illustrates just how much of the total wheel HP is being delivered to each of the front and rear wheels across these three modes.
