1 Technical data
The ECU MS 25 Sport engine control unit manages common rail Diesel engines with
solenoid valve injectors up to 8 cylinders. The MS 25 Sport utilizes software development
process based on MATLAB® & Simulink®.
1.1 System Layout
– Controls max. 8 cylinders with 5 injections (Pilot2-, Pilot1-, Main-, Post2- and Post1 in-
jection)
– Two engine hydraulic bank measurement, control and monitoring strategy for rail
pressure with one (FMU) or two actuator (FMU+PCV) operation
– Two engine bank related separated lines for physical air mass, boost pressure and
turbo speed determination and control
– One lambda LSU 4.9 measurement supported directly by MS 25 Sport. 2-bank meas-
urement and control as option via external CAN measurement
– Integrated torque‐structure for power control functions as speed‐ and launch limita-
tions or regulations. Gear and map position dependent torque limitations
– Gear cut support with rail pressure control feedback
