Simply expressed, the output increase is achieved by adjusting the quantity of fuel-air mixture and the ignition timing. In this process the injectors play a major role, they control the amount, timing and fuel injection pressure. Vector tuning modules picks up the control unit’s data, processes and optimizes it through Vector module's own microprocessor and then sends the modified data to vehicle's Electronic control unit (ECU) to be processed safely within the vehicles own factory set safety parameters.
