KW DDC ECU – control your new Audi RS3 with your smartphone!


The current Audi RS3 with its 2,5-liter fife-cylinder turbo and 367 hp is a serious competitor for the BMW M235i, Mercedes-AMG A45, VW Golf R and Co. in the sporty compact car segment. Compared to the conventional A3, the sporty RS3 is already in series lower by 25 mm.


And the Audi specialist MTM proofs that there is even more to get out of it. The five-cylinder now delivers 435 hp and the maximum torque is 605 Nm.

At the moment MTM is also testing a 502 hp version.


To ensure that the driver is not overstrained with this MTM performance explosion, the refiner equipped the car with an adaptive KW DDC ECU coilover kit. The suspension kit in the Comfort mode automatically adapts to the respective driving situation.


But our KW DDC ECU coilover can do much more! Via our DDC App you can adjust the dampers with your smartphone. In real time, the KW DDC App allows to intuitively adjust the damping characteristics to the personal driving preferences, loading conditions or to the wheel / tire combination.

With the App, the adaptive dampers of the KW DDC ECU coilover kit can continuously be adjusted per axle from the maximum Comfort with a very soft damping (displayed in the App with 0%) up to the Sport+ damper setup (displayed in the App with 100%). The KW DDC App features a vehicle-specific safety-related control range.


In mode Sport+, the KW dampers give the RS3 a direct and unadulterated driving behavior, a setup that is ideal for demanding trips on curvy roads with many load changes.


The Sport mode on the other hand is perfect for driving on the highway with long curves; while the Comfort mode is the ideal travel companion on poorly maintained roads.

The communication between smartphone and the KW DDC ECU suspension control takes place via a secured WiFi connection and the optional WLAN module.


The tested lowering range allows an adjustment between 10 – 35 mm, which is set directly on the stainless steel struts at the front axle and via the rear axle height adjustment. The Apple iOS and Android compatible App is available for free in the respective “App-store”.
