This tuning box already includes a 2-channel system.
In this vehicle, the SPEED-BUSTER Chiptuning-Box is connected to two different sensors of the engine (not a pure rail pressure elevation). The SPEED-BUSTER ® Chiptuning-Box is - depending on the vehicle type - connected to various sensors of the engine. By our vehicle-specific wiring harnesses with original connector the data from the sensors are routed directly to the tuning box, recalculated by microprocessor in real-time and from there further to the engine control unit. By the recalculation based on vehicle-specific maps various motor parameters can be optimized - the result is optimum efficiency, more power and more torque.
