6 MS4.3 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.

6.1 MS4.3 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.

6.1.1 Electronic Control Unit (ECU) and external H-Bridge

The ETC-System must be controlled by a Bosch Motronic MS4.3. If an external H-Bridge driver is required for a dual ETC application, it must be supplied from Bosch Motorsport for proper driving and diagnostics (P/N: F 01E B01 637). The engine control and the ETC-control must be accomplished using the same ECU.

6.1.2 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.

6.1.3 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.

Motorsport


6.1.4 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.

6.1.5 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.

6.2 MS4.3 Software requirements

The ECU (as given in 4.1.1) 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.

6.2.1 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.

6.2.2 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.

6.3 MS4.3 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.

6.3.1 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).

6.3.2 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.

6.3.3 Damage to the system

In the event that damage or malfunction to the hardware components mentioned in sections 6.1.1 to 6.1.5 occurs, the car must be stopped or taken out of operation respectively.

Motorsport


6.3.4 Modifications of system components

Any modification to the components listed in sections 6.1.1 to 6.1.5 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.

7 MS15.X Grand Am Specification The Bosch Motorsport 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 can not be ensured.

7.1 Software requirements MS15.X

The ECU (as given in 7.1.1) must be operated by original Bosch Motorsport software, Version 1.03. Software V1.03 removes the ability for the teams to calibrate the torque limiting functions of the ECU such as smoke fuel limit and torque fuel limit. This software also limits launch control and adds filtering limits to torque limiting variables to disable the possibility of artificial traction control. The use of software which is not developed for Grand AM, 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.

7.1.1 V1.03 Grand Am Specific Software handling.

After successful integration of the engine package into Gram Am, the ECU is considered “locked” and the development calibration is converted by Bosch Motorsport to V1.03 software. Only Grand Am and Bosch motorsport maintain a copy of the .a2l file necessary to modify the main fuel limiting table on V1.03 software

7.1.2 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.

7.1.3 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.

7.1.4 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.

Motorsport


7.1.5 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.

7.1.6 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.

7.2 MS15.X Operating conditions

The safety functions, error detection and error reactions of the Bosch Motorsport 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.

7.2.1 Operating the vehicle

Vehicles with Bosch Motorsport 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).

7.2.2 Third parties

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

7.2.3 Damage to the system

In the event that damage or malfunction to the hardware components mentioned in sections 7.1.1 to 7.1.6 occurs, the car must be stopped or taken out of operation respectively.

7.2.4 Modifications of system components

Any modification to the components listed in sections 7.1.1 to 7.1.6 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
