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

1.4 Input Channels

Only active (0 to 5 V) exhaust gas temperature sensors are supported.

See chapter Initial Data Application [}22] for further information and calibration ex-

amples for different sensors.

1.5 Output Channels

The MS 25 Sport has 8 injector power stages on three banks. Only solenoid valve type

common rail injectors are supported. Injector current profile must be calibrated for used

injector type (CRIN1, CRIN3, CRI2.X, ...).

1.6 Power Supply

Please ensure that you have a good ground installation. That means:

– A ground that has a solid, low resistance connection to the battery minus terminal.

– Connection should be free from dirt, grease, paint, anodizing, etc.

– Use large diameter wire.

– More metal-to-metal contact is better

Connection of the power supply

The following notations for power signals are used:

– Term 15 is a switched battery rail controlled by the Engine On-switch.

1 | Technical data

10/40 Engine Control Unit MS 25 Sport Bosch Motorsport

– Term 30 is an unswitched battery positive rail (same as battery positive terminal).

– Term 31 is an unswitched ground rail (same as battery negative terminal).

– MS 25 Sport needs constant Term 30 and ECU should be powered on and off only

with Engine On-switch (Term 15). Constant voltage on Term 30 is required to preserve

critical information during ECU shutdown.

CAUTION

Wrong polarity / high currents

Wrong polarity of the terminals and high currents damage the MS 25 Sport. Be careful to

observe current limits of wires and connector pins!

1.7 Trigger Wheel

The software assumes a toothed trigger wheel for proper operation. The number of the

teeth is hard coded by Bosch Motorsport and can’t be changed by the customer. Custom

gap teeth numbers are optional.

We recommend 60 (-2) teeth as shown in the following picture. The crank wheel trigger

sensor must be an inductive type for the default configuration, Hall-effect crank sensor is

optional and requires software change.

The camshaft trigger sensor is a Hall-effect type with a single tooth trigger wheel, but

other configurations can be configured with calibration. Inductive cam sensor is optional

and requires software change. The picture below shows the correct installation position.
