2.0 TSI EA888 evo4 upgrade Output stage fuel pump control unit

Upgrade Control unit for the fuel pump in the 2.0 fourth-generation TSI engines. When increasing performance, the original pump or output stage often reaches its limit. We have set ourselves the task of finding a simple way to give the original pump a helping hand. And it's completely plug and play! We generate more current with a more powerful fuel pump control unit. This enables the pump to deliver more fuel. Simple and efficient. Features: more volume simply plug & play replacement No further changes necessary, for example to the engine software with standard software! Attention: The module only fits the "large" engines such as the Golf 8R. Not suitable for the "small" engines such as the GTI. If you have installed a new fuel pump, it can often happen that it does not always work correctly. This is usually due to a defective pump. Our experience has shown that this is not the case, but that the control unit is defective or its performance is reduced. Like many other components, the control unit also wears out. The control unit should always be replaced together with the pump to ensure that there is sufficient power. After installation, check the fuel gauge and readjust it with VCDS if necessary. If your pump does not work correctly, please have the software tuner programme the pump control (PWM signal) to series!
