MSC plug & drive modules basically can be connected to sensors, actuators or data buses. MSC means "Mapped Signal Controller".
The MSC modules are fully digital microcontroller circuits, which monitor the ECU signals and if necessary change the signals in order to increase engine performance.
MSC powermodules, 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. First our engineers read maps and limiters from the ECU memory and develop a basic map for the MSC module. Then we start fine tuning the system on road and rolling road tests. Here we determine the best values for driving dynamics, engine performance, exhaust gas temperatures and emissions.
Other MSC powermodules are attached to actuators. Example: the injectors of a TDi engine´s UIS system. Here the MSC 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 analyzed here also and the limiters of the ECU´s plausibility checks are programmed into the MSC module´s firmware. The fine tuning of the MSC software is a major part of the development.
The possibilities, which offer MSC modules for data buses, are particularly interesting. It is possible to change engine parameters which are not forwarded to the ECU by direct signal line but by CAN data bus. The MSC module monitors and controls here complete data communication between the individual electronic devices.
Dependent on the used injection system, we select a technical solution, which offers the best performance increase for your vehicle.
We realize a performance increase which represents the best compromise between driving fun, engine durability and exhaust gas emission laws.
