Engine Control Unit MS 7.8

Engine Control Unit MS 7.8

The MS 7.8 engine control unit manages gasoline engines up to 12 cylinders. The MS 7 line features a powerful digital processing core with floating point arithmetic and a high-end FPGA for ultimate performance and flexibility. The MS 7 line utilizes a software development process based on MATLAB/Simulink which significantly speeds up algorithm development by using automatic code and documentation generation. Custom functions can be generated quickly and easily. The flexible hardware design allows the MS 7.8 to support complex or unusual engine or chassis configurations.

Version MS 7.8-ADV was developed for use with Lambda Sensor LSU ADV (higher max. Hexagon temperature).
