Haldex Controller Gen2 Plug And Play

The HPA Motorsports Haldex Controller Gen2 Plug And Play allows you to customize your vehicle's second-generation Haldex all-wheel-drive system for tailored performance. This controller is suitable for street, track, or daily driving, offering multiple modes to adjust system engagement. You can select full lock-up, map-based lock-up determined by throttle, speed, or boost signals, or even disable the Haldex system entirely for activities like burnouts or when prioritizing fuel economy. The controller provides several optional Haldex modes, including Stock mode, adjustable lock-up from 100/0 to 50/50, and map-based configurations for throttle, speed, boost, or a combination of throttle and speed signals. It also features a Haldex Off mode for dyno runs, burnouts, or fuel economy. User-selectable settings include Lock Mode, adjustable in 10% increments (Front/Rear), and mapping based on throttle position (also in 10% increments). Vehicle Speed Mode allows adjustments in 20 km/h increments, while Boost Pressure Mode offers increments of 100 mBar (1.45psi). A Passthru Mode ensures all original car signals are passed through to the Haldex system. This plug-and-play controller is compatible with the 2008-2009 Mk2 Audi TT 3.2. An optional manual switch for programmable quick mode selection is available separately and requires wiring. The controller connects via Bluetooth and can be managed through a free app available on iTunes and Google Play, with a default pincode of 1234.
