2 Technical Data
The MS 6 engine control unit features a powerful digital processing dual-core with floating point arithmetic and a high-end field programmable gate array FPGA for ultimate performance and flexibility.
The software development process is based on MATLAB® & Simulink®. It significantly
speeds algorithm development by using automatic code and documentation generation.
Custom functions can be generated quickly and easily. The flexible hardware design allows
the MS 6 to support complex or unusual engine or chassis configurations. Integrated logger control areas present a cost efficient and weight optimized all-in-one solution.
2.1 System Layout

traction limitations or regulations
– Two engine bank related separated lines for physical air mass determination, influ-
enced by own Lambda corrections
– Options from simple gear cut support up to complete gear change functions
– Different target maps to differ applications like Lambda-, spark- and electrical throttle
controls
– State of the art engine functions like fuel cut off, idle control, injection valve correc-
tions and knock control are already integrated in the basic program structure.
– Sequential fuel injection realized also for asymmetric injection and ignition timings
– Various networks like 2 Ethernet-, 1 USB, 1 LIN for system communication, 3 configur-
able CAN for external device communication and 1 RS232 for online telemetry data.

2.1.1 Structure MS 6 Devices, Licenses and Order
Numbers
To accommodate the wide range of different engine requirements and race track operating conditions, the MS 6 Motronic system is classified into the main groups high- and low
pressure injection support, subdivided into fully equipped- and functional reduced versions.
Beside the change from low- to high pressure systems, all limited functions may be activated later. The license concept is related to the individual device and the requested upgrading.

Offer drawing Available at Bosch Motorsport website on MS 6 product page.
3D Data Available at Bosch Motorsport website on MS 6 product page.
Recommendation
Use rubber vibration absorbers for soft mounting in the vehicle. To assist the heat flow,
especially if HP injection is active, the device has to be mounted uncovered and air circulation has to be guaranteed around the entire surface area.
Inside touring cars placement passenger side is favored, open connectors should not be
uncovered to vertical axe. It has to be assured in mounting position that water cannot infiltrate through wiring harness into the ECU and that the pressure compensating element
and the sealing in the revolving groove do not get submerged in water. Wiring harness
needs to be fixed mechanically in the area of the ECU in a way that excitation of ECU have
the same sequence.
2.3 Electrical Data
Power supply 6 to 18 V
CPU Dual Core 667 MHz; FPGA
2.3.1 Communication
3 x CAN The MS 6 has 3 CAN buses configurable as input and output. Dif-
ferent baud rates are selectable. Please note that the MS 6 contain
integrated switchable 120 Ohm CAN termination resistors.
1 x LIN The Bus is not configurable by the customer, but Bosch Motorsport
offers data selectable protocols to integrate LIN based devices into
the system.
2 x Ethernet Integrated are 100 Mbit full duplex Ethernet communication ports,
internally connected with an Ethernet switch. The ports have “cable
auto crossover” functionality
1 x USB For data transfer to an USB-stick
1 x RS232 One serial port with programmable baud rate for online telemetry
1 x Timesync Coordination

2.3.2 Inputs
The analogue inputs are divided in different hardware classes and qualities.
3.01 kOhm pull-ups are fixed or switchable designed to assist passive sensor elements like
NTC temperature sensors or to change to active signal inputs.
Some of the inputs assist only active sensors and offer no pull-up.
To improve measurement tasks, angle related measurements are an option for some inputs, mainly used for engine related leading signals.
The connection between function and related input is free selectable, beside electronic
throttle functionalities.
All linearization mappings are open to the customer, some signals offer online modes to
calibrate gain and offset.
Digital inputs for speed measuring offer divers hardware options to connect inductive- or
digital speed sensors.
Please respect: for camshaft- or wheel speed signals Hall-effect or DF11 sensors have to
be used and for wide range Lambda measurement and control the Lambda sensor Bosch
LSU 4.9 has to be used.

2.3.5 Supply System
Please ensure that you have a good ground installation with a solid, low resistance connection to the battery minus terminal. The connection should be free from dirt, grease,
paint, anodizing, etc.
– MS 6 power consumption at appr. 13 V (vary according to use cases)
– ~ 25 - 30 amps (4 cyl. FDI at 8,500 1/min/200 bar single injection, 1 MSV, 1 elec-
tronic throttle, standard chassis equipment)
– ~ 35 - 40 amps (8 cyl. FDI at 8,500 1/min/200 bar single injection, 2 MSV, 2 elec-
tronic throttle, standard chassis equipment)
– Power consumption of LP-injectors, actuators and coils are to calculate separately.
– The MS 6 power supply is separated into the maintenance of controller and power
stages.
– Ensure controller supply is activated before the power stages.
– The MS 6 is able to control a main relay or even the power box itself via a low side
output.
– As long as the controller is activated, data logging, telemetry and communication is
also ongoing.
– The engine On/Off switch activates the ignition and injection outputs to enable en-
gine start separately from power supply.

2.3.6 Pin Layout
The pin layout is also available at Bosch Motorsport website on MS 6 product page.
Most of MS 6 functions to pin relations may be modified to projects demands.
Please see details in the function description SWITCHMATRIX.
Bosch Motorsport tests check the defined connections of the pin layout.
Using a MS 6.1 or MS 6.3 version ensure not using analogue inputs of the measurement package without enabled license.
For MS 6.1 and MS 6.3 these hardware-options are only available if MS 6 measurement package is in use.

Wiring
Bosch Motorsport recommends using the specified cable material and harness layout for
automotive connectors and wiring applications.
For Ethernet and USB connection CAT5 specified material is recommended and the pairs
and shield connections have to be strictly respected as shown in the wiring diagram.
For USB, the maximum wiring length is limited to 3 m and it is not allowed to be included
into a common harness and also there is no interruption allowed.
Due to installation condition, the length may have to be reduced.
Keep network wiring in distance to main sources of electrical noise like coils, coil- and HPinjector wirings and also in distance to any telemetry transmitter.

CAN-networks need a 120 Ohm termination at 2 ends of the wiring.
The MS 6 is able to switch on an internal 120 Ohm termination, set CWCANx_TERM true
to enable the termination.
For wiring layout, respect the common rules of failure reduction like separated sensor
power supply between important system sensors (e.g. camshaft detection) and measure
options (e.g. damper position).
Be ensure HP-injectors, electronic throttles and other high frequently switched actuators
are connected within the wiring limits of 2.5 m and all wires are manufactured as twisted
pairs.
If using a preinstalled production harness, first verify the way of sensor- and actuator controls.
Often production parts have to be connected to 12 V power supply and actuators are
controlled in different ways. The production harness may need to be modified.
Office harness
Reduced layout to realize communication between PC, MS 6 device and Display DDU, recommended for flash configuration, display configuration and installation tasks. Bosch
Motorsport part number: F 02U V01 809
2.3.8 Ignition Trigger Wheel
To detect the engine position and to calculate the exact crankcase position, the system assumes toothed trigger wheels for proper operation. Recommended is to use 60 (-2) teeth
for the flywheel and one teeth for the camshaft detection. Modifications of the mechanical
designs are possible, such as using quick-start production designs for the camshaft or different number of teeth for the flywheel (limited to 30 to 60 teeth).
NOTICE
Less number of teeth reduces the accuracy of the system angle measurement.
Not usable are flywheels with 4-1 or 6-1 teeth. Please follow the description below as recommendation for the mechanical dimensions.
Recommended values:
– D = min. 160 mm
– h1 = 3.5 mm
– h2 = h1/2 (important for the use of inductive sensor)
– LSKW = 0.8 mm +/- 0.3 mm
– t = min. 5 mm
– LNSW = 1.0 mm +/- 0.5 mm
