Introduction to system components – MS4.3 ECU, C40 data logger, dongle, MSA Box, etc… Introduction to Bosch Motorsport calibration tools Introduction to calibration software

The contents of the training are not limited to the topics listed above, if a team has a preference for the content this can be catered to. Training classes are typically held at the Bosch US Automotive Headquarters in Farmington Hills, MI. If you are interested in receiving training on Bosch products please contact Bosch Motorsport. The cost for these training sessions will depend on the number of registered participants.

3.2 Individual engine builder training Bosch offers dyno calibration and on-site support for all Grand Am kits. This can be used as a training seminar at the customer’s dyno. The engine builder or team pays for engineering support, travel, and overnight expenses during the entire support period according to the current Bosch Motorsport Test and Race Support documentation for test and race day events. Other individual trainings are available upon request.

3.3 Track support Bosch Motorsport offers full and shared track support services to all registered Grand-Am teams running a Bosch spec system during the 2012 racing season (coverage, pricing and scheduling options available upon request). Please contact:

Bosch Motorsport - North America Benjamin Kaminsky 248.876.1178 [email protected]

4 MS4.3 Integration

4.1 Base engine calibration conversion An engine calibration provided to Bosch Motorsport in a useable format can be converted to a Bosch format as a starting point for new projects. The cost of this service is $350 per calibration. Contact a Bosch Motorsport representative for more information with regards to useable file formats for conversion.

4.2 Bosch Motorsport crank and cam triggering requirements

4.2.1 Sensor constraints:

Crankshaft speed sensors: Inductive speed sensor (recommended: 0 261 210 136). Camshaft position sensor: Hall effect speed sensor (recommended: 0 232 103 037).


mailto:[email protected]

Motorsport

4.2.2 Crankshaft trigger wheel:

It is required to use a standard Bosch 60 minus 2 tooth trigger wheel for crankshaft position sensing for all piston engine applications, see Appendix for trigger wheel drawing. Rotary applications use a 36 minus 2 trigger wheel. This drawing will be provided separately.

4.2.3 Camshaft trigger wheel and sensor installation:

There are two different configurations for crank & cam synchronisation one for fixed cam applications and another for continuously variable camshaft phasing applications. Fixed cams require a single tooth wheel whereas variable cams require a Bosch 4-tooth quick start wheel, see Appendix for trigger wheel drawing and installation instructions for both applications. It is imperative that cam sensors can not exhibit ‘latching’ behavior sometimes seen in production sensors. This occurs when the cam sensor sees a high tooth and the sensor output value continues to read high even when a low tooth passes the sensor. Sensors used with new kits must be measured beforehand to ensure that a low tooth always corresponds with a low reading on the sensor and vice versa.

4.3 Engine harness information

4.3.1 Main engine harness grounds:

Engine harnesses provided by Bosch for the Spec ECU system may have ground terminals in the engine compartment. It is required that these terminals be securely grounded to the engine block, and have a good ground path to the battery negative terminal. The ring terminal connections must make complete contact with bare metal and the mating contact surface may not be anodized, painted, or covered in any way unless authorized by Bosch Motorsport. It is acceptable to provide extra grounding wire, or ground straps, to supplement the ground terminals supplied in the engine harness so that the connection between engine ground wires, chassis, and battery negative is sufficient.

4.3.2 Lambda sensors:

All engines using MS4.3 engine management will be required to run Bosch LSU 4.9 lambda sensors (part # 0 258 017 025). The new LSU 4.9 sensor is designed for high vibration and high temperature applications. LSU4.9 sensors are available from Bosch Motorsport suppliers listed in section 1.3.

Bosch LSU 4.2 sensors (part # 0 258 006 065 or 066) are non-compatible with the MS4.3 system.

4.3.3 External ignition driver stages

Various applications require the use of external ignition driver stages due to using non-transistorized coils. The stock Porsche 997 and most BMW ignition coils require two 3-channel Bosch external coil drivers (part # 0 227 100 203) for proper functionality. The Grand Am spec engine harness is specifically designed for these driver stages. Driver stages are available from Bosch Motorsport distributors listed in section 1.

4.3.4 General Sensor/Connector Information

If non-Bosch sensors or actuators are used, it is the team or engine builder’s responsibility to provide connectors for the harness builds if they are not readily available. All non-Bosch sensor and actuator characteristics must also provided by the customer.


Motorsport 4.4 Chassis harness information

A Bosch Chassis Harness is a required part of the Grand Am spec engine management system.

4.4.1 General information

The following list summarizes important integration notes for the chassis harness interfaces incurred from the introduction of the MS4.3 spec ECU.

Pit-speed switch will be active low, NOT active high. Fuel map switch will be active low, NOT active high, see output table below. Hall effect wheel speed sensors are required, VR sensors are non-compatible.

4.4.3 Dyno harness information

Bosch Motorsport will support the extension of chassis harnesses to fit to individual engine builder’s dyno testing needs. If you intend to purchase a chassis harness for this purpose, please contact a Bosch Motorsport engineer for help with this option. This solution could provide a low cost option for a dyno harness.

5 Electronic Throttle Control (ETC) Specification The Bosch Motorsport ETC-System was developed exclusively for use in competition vehicles during motorsport events. Its operation is solely permitted, if all given system requirements are met. The system is in a prototype status and must not be used if one of the requirements is not complied with, otherwise proper functionality of the engine controller and ETC-System can not be ensured. The complete production functionality can not be implemented in to a racing system due to their limited memory space which could lead to some remaining risks when using electronic throttle functions in motorsports. Prior to receiving a Bosch MS4.3 ECU with ETC capability each team owner is required to sign a document containing section 5 of the 2011 Grand Am Continental Tire Challenge Series MS4.3 ECU Integration document stating that it has been received and acknowledged.

5.1 Hardware requirements All of the following requirements must be met. Violation of one or more requirements leads to expiration of the operating permit. Rebuilds, damages or any alterations without approval of Bosch Motorsport of the parts mentioned in 5.1.1 to 5.1.5 will also lead to expiration of the operating permit.


Motorsport

5.1.1 Electronic Control Unit (ECU)

The ETC-System must be controlled by a Bosch Motronic MS4.3. The engine control and the ETC-control must be accomplished using the same ECU.

5.1.2 Electronic throttle body

The throttle body must be a Bosch DV-E5 type or a part that has formally been authorized and tested by Bosch Motorsport. Rebuilds of the throttle body must only be done at Robert Bosch GmbH or Bosch Motorsport. The potentiometers used for throttle position measurement must have a specific relation to each other, the two must be redundant.

5.1.3 Accelerator pedal position measurement

The accelerator pedal position measurement must be done with a redundant linear or rotary potentiometer sensor. The sensor must have two fully independent measuring circuits, meaning the sensor 5V power supplies, grounds, and signal outputs must be carried out twice. One broken measuring circuit in the sensor must not influence the second circuit. The sensor must meet motorsport durability and quality requirements. The sensor must be released for use for acceleration pedal measurement in an ETC-System by Bosch Motorsport. The use of two single circuit sensors is not permitted. The potentiometers must have a specific relation to each other. One potentiometer must have exactly half the output of the second.

5.1.4 Emergency kill switch

The system must have an emergency kill switch. The actuation of the switch must either cut the throttle actuator from its power supply or disconnect the main power supply of the engine management system. The emergency kill switch must be clearly identifiable and accessible in the car and must be marked accordingly.

5.1.5 Wiring harnesses

The wiring harnesses between main power supply, emergency stop switch, acceleration pedal sensor, ECU, and throttle actuator must be manufactured or approved by Bosch Motorsport.

5.2 Software requirements The ECU (as given in 5.1.1) must be operated by original Bosch Motorsport software, which must be approved and developed for ETC control in the respective ECU. The use of software which is not developed for ETC control, alteration of any Bosch Motorsport software, or use of software which was not designed for the respective ECU leads to expiration of the operating permit.

5.2.1 Program part

The programmed ECU software part may only be modified by Bosch Motorsport. The customer is required to use only the most current software release.

5.2.2 Data part

The calibration data part can be changed by the customer only with calibration tools that are approved by Bosch Motorsport. Nevertheless improper data application can lead to critical situations. Therefore, changes in the data part must be done by individuals, who are familiar with the function of the engine management’s software and hardware, especially the ETC components and functions. The functionality of the system is described in the documentation delivered with the system.


Motorsport 5.3 Operating conditions

The safety functions, error detection and error reactions of the Bosch Motorsport ETC-System may vary (due to motorsport-purpose and hardware conditions) from systems used in production cars. Therefore the system must be checked for faults before each start up. The functionality of the diagnostics and safety systems is given in the system documentation and each driver must get an introduction to the use of the emergency kill switch operation.

5.3.1 Operating the vehicle

Vehicles with Bosch Motorsport ETC system may only be driven by professional race drivers within motorsport events, or by persons who are familiar with the system for test purpose on closed roads. In both cases the driver must be informed about function and possible error reactions of the system and also he must know possible emergency actions (e.g. tripping the emergency kill switch).

5.3.2 Third parties

Vehicles with Bosch Motorsport ETC-System must not be passed to third parties without giving notice of these system requirements. The recipient must acknowledge the notice by signature.

5.3.3 Damage to the system

In the event that damage or malfunction to the hardware components mentioned in sections 5.1.1 to 5.1.5 occurs, the car must be stopped or taken out of operation respectively.

5.3.4 Modifications of system components

Any modification to the components listed in sections 5.1.1 to 5.1.5 which is not approved by Bosch Motorsport will lead to expiration of the operating permit. A car with modified or incomplete hardware components must also be stopped or taken out of operation respectively.
