The TouchMotion AWD Programmer from HPA Motorsports is a plug-and-play device compatible with Gen 1 Haldex 4-motion controllers.

Designed to be fully compatible with both OEM or aftermarket installed Haldex 4-motion differential controllers, the Touch Motion plugs inline and hands control of the rear end behavior over to the driver.

HPA's TouchMotion AWD Programmer consists of three main components. A trunk-mounted control unit, a cable to connect the new controller inline, and a wireless touch screen interface are also needed.

The Touch Screen Interface features a live interactive display that tells the driver how much torque is being transmitted to the rear wheels at any time and offers access to a number of basic and advanced configurations. The touch screen is merely the user interface for the TMAP system and does not need to be present to run the controller as the controller will operate under the last user settings inputted.

Through the touch of the screen, drivers can select not only the preset operating modes of the differential such as Stock, Economy, Sport or Competition, they can go beyond with Dynamic and Race-Speed where they can individualize the profile based on driving habits and needs.

Under Race-Speed, drag racers can digressively or progressively adjust rear engagement. Example; when launching AWD vehicles from prepared surfaces, typically some front wheel spin is desired to better facilitate engine acceleration prior to full rear wheel power transfer avoiding engine bog. As the speed down the track increases, the rear differential engagement can be scaled straight back to reduce drag and increase top speed.

Under Dynamic, drivers can configure which modes to toggle between and what the transitions will be triggered by. Example, set in economy mode for daily commuting, the driver wishes to toggle straight into an aggressive full torque transfer configuration and back when overtaking a vehicle may be required.

Within advanced settings, over-steer compensation can be reduced for drivers that wish to enable more drift tendency, and engagement of differential under braking can be toggled on or off depending on driving style, comfort, or usage habits.

HPA has developed a tool that will allow the driver to tune the drivetrain to meet their specific needs.
