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 allpiston engine applications, see Appendix for trigger wheel drawing. Rotary applications use a 36 minus 2trigger 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 andanother for continuously variable camshaft phasing applications. Fixed cams require a single tooth wheelwhereas variable cams require a Bosch 4-tooth quick start wheel, see Appendix for trigger wheel drawingand installation instructions for both applications.

It is imperative that cam sensors can not exhibit latching behavior sometimes seen in productionsensors. This occurs when the cam sensor sees a high tooth and the sensor output value continues toread high even when a low tooth passes the sensor. Sensors used with new kits must be measuredbeforehand to ensure that a low tooth always corresponds with a low reading on the sensor and viceversa.

4.3 Engine harness informat ion

4.3.1 Main engine harness grounds:Engine harnesses provided by Bosch for the Spec ECU system may have ground terminals in the enginecompartment. It is required that these terminals be securely grounded to the engine block, and have agood ground path to the battery negative terminal. The ring terminal connections must make completecontact with bare metal and the mating contact surface may not be anodized, painted, or covered in anyway unless authorized by Bosch Motorsport. It is acceptable to provide extra grounding wire, or groundstraps, to supplement the ground terminals supplied in the engine harness so that the connectionbetween 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 hightemperature applications. LSU4.9 sensors are available from Bosch Motorsport suppliers listed in

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-controlmust 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 byBosch Motorsport. Rebuilds of the throttle body must only be done at Robert Bosch GmbH or BoschMotorsport. The potentiometers used for throttle position measurement must have a specific relation toeach other, the two must be redundant.

5.1.3 Accelerator pedal position measurementThe accelerator pedal position measurement must be done with a redundant linear or rotarypotentiometer sensor. The sensor must have two fully independent measuring circuits, meaning thesensor 5V power supplies, grounds, and signal outputs must be carried out twice. One broken measuringcircuit in the sensor must not influence the second circuit. The sensor must meet motorsport durabilityand quality requirements. The sensor must be released for use for acceleration pedal measurement in anETC-System by Bosch Motorsport. The use of two single circuit sensors is not permitted. Thepotentiometers must have a specific relation to each other. One potentiometer must have exactly half theoutput 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 throttleactuator 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 markedaccordingly.

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.

5.3 Operat ing con di t ions

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. Thereforethe system must be checked for faults before each start up. The functionality of the diagnostics and safetysystems is given in the system documentation and each driver must get an introduction to the use of theemergency 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. Inboth cases the driver must be informed about function and possible error reactions of the system and alsohe 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 ofthese 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 5.1.5occurs, 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 BoschMotorsport will lead to expiration of the operating permit. A car with modified or incomplete hardwarecomponents must also be stopped or taken out of operation respectively.
