Bosch Motorsport | Engine Control Unit MS 6.4

Engine Control Unit MS 6.4

 Optimized for low and high pressure injection
 HP package for flat and V-engines inclusive
 Measurement with 38 analog inputs
 Multiple Software options available

The MS 6.4 engine control unit manages gasoline engines up to 12 cylinders. As a member of our MS 6
family it features a powerful digital processing corewith floating point arithmetic and a high-end FPGA
for ultimate performance and flexibility. The MS 6
family utilizes a new software development process
based on MATLAB/Simulink which significantlyspeeds algorithm development by using automatic
code and documentation generation. Custom functions can be quickly and easily generated. The flexible hardware design allows the MS 6.4 to supportcomplex or unusual engine or chassis configurations.
