In this case, the enhanced performance is achieved by dynamically matching the response of the injection pump's fuel regulator to the control device, which thus adjusts the amount of fuel delivered by the pump. The increase in power is thus achieved by indirect control. Increased power is obtained through direct control of fuel delivery by comparing the characteristics of the injection solenoid valves against the initial parameters. The increase in power is obtained in a similar manner to the common rail system.
All systems achieve enhanced performance only by modifying the fuel injection parameters.
The turbo boost pressure is not actively influenced. What is more, the functions of the control device are fully maintained. The manufacturers' ABS and ASR settings, as well as those of the other sensors remain unchanged, which ensures genuine safety of use. The Tuning Box does not alter the exhaust fume characteristics. The engine's response is smooth and immediate, with no misfire or sudden unexpected surges of power.
