How does the consumption reduction work?

In modern vehicles, the control, regulation and monitoring of all engine functions is taken over by the engine control unit. The data stored there, such as e.g. the fuel injection, the control of the ignition timing or the air volume are read out and adjusted accordingly to optimize consumption.
From a technical point of view, this gives the vehicles an increase in torque. Not in full load operation, but mainly in the middle and lower speed range, where the power is needed. This means that more torque is available at lower speeds, which results in lower consumption.
In concrete terms, this means that the acceleration phases are shorter thanks to the increased torque because the target speed is reached more quickly. However, more fuel is injected in this shorter time in order to obtain more torque. You then go into a rolling phase in which, thanks to the increased torque, you have to accelerate less to keep the vehicle at the target speed. In addition, the rolling phase becomes longer at the expense of the acceleration phase. That is the simple explanation why chip tuning achieves a reduction in consumption despite the additional power.
Depending on the type of vehicle and the area of ​​application of the vehicle, there are very different requirement profiles. In chip tuning, the standard software from the engine control unit is individually tailored to your needs and the corresponding area of ​​application in order to achieve an optimal result. Optimized engine management is not only cost-efficient, it also leads to significantly improved driving behavior and fewer emissions.
