How it works

Technical background

The Plug & Drive module can be connected to sensors, actuators or data buses.
The KRAFTWERK ECU modules are fully digital microcontroller circuits, which monitor the ECU signals and if necessary change the signals in order to increase engine performance.

KRAFTWERK ECU modules, which are attached to sensors (e.g. rail pressure sensor on Commonrail engines), monitor the output signal of the sensor and forward it depending upon operating conditions modified or unmodified to the engine control unit. This way a higher fuel pressure raises engine performance at certain load conditions. Firstly our engineers read maps and limiters from the ECU memory and develop a basic map for the Power Module. Then they start fine tuning the system on road, dyno and rolling road tests. Here they determine the best values for driving dynamics, engine performance, exhaust gas temperatures and emissions.

Other Power ECU Modules are attached to actuators. Example: the injectors of a TDi engine´s UIS system. Here the module monitors the output signals of the ECU and forwards these modified or unmodified to the actuator. Thus in this example injection time is expanded in dependence of engine speed and engine load.

The software of the ECU is thoroughly analysed and tested within strict limits of the ECU´s protective parameters. The fine tuning of the software is a major part of the development.

Our engineers perfectly translate the performance increase which represents the best compromise between driving fun, engine durability and exhaust gas emission laws.

How the KRAFTWERK ECU Module works

The Plug & Drive Principle



The fitment of the KRAFTwerk ECU Module is very simple and done in few steps:
1. Pull the plug from the Fuel Rail Pressure Sensor and mount the appropriate plugs of the Y-Cable in-between.

The Fuel Pressure Sensor is situated either in the middle or at the end of the fuel rail line.
2. Now connect the Kraftwerk Module with the cable.
3. Please make sure that you hear and auditable ‘click’, which confirms the correct installation. If installed incorrectly, a warning light (engine) lights up in the cockpit.
