After creating the legendary Active Sound Gateway and Active Suspension Control apps for all the car enthusiasts, we are now presenting a brand new product. For years we have been developing and distributing electronically controlled active solutions to fine-tune your car to your needs. Our new Control Unit allows you to electronically control the exhaust flaps of your car with a mobile app and in combination with your original car's buttons. Factory valved cars (electronic valves) have got "original mode", that allows you to easily go back to the original exhaust system settings of your vehicle with just one click. You can specify in which speed or RPM ranges the Active Valve Control system automatically opens or closes the valve in the exhaust system, and so changing the sound in specified speed and RPM ranges. To take care of your engine, therefore, you can set up the desired RPM level, when the valve automatically opens - so-called "safety opening". Different ranges of speed and RPM can be set for the valves behaviour and set up several profiles, so with just several clicks you can make your car run quietly or make it roar like a real roadster. Depending on the vehicle and model, different profile change mechanisms are available, for example: driving profiles of the respective vehicle alternator, ESP button or Start & Stop Automatic button. Our Active Valve Control can be used on countless vehicles of all premium manufacturers, such as Audi, BMW, Mercedes-Benz, Porsche, Range Rover, Volkswagen, and many more. The Active Valve Control system is available for both, electrically and vacuum controlled exhaust systems.
