900- Electric and Data Acquisition

900 - 1 Software

RaceCon

BOSCH Motorsport supplies the RaceCon software with which the majority of

functions of the R8 LMS can be parameterised. This includes common functions

such as:

-

Creation of display pages

Lap trigger configuration

Outing and lap counter configuration

Pit speed configuration

Suspension travel calibration (optional)

Steering angle calibration

Calibration of engine functions (butterflies, throttle pedal, camshafts)

The R8 LMS is delivered with a ready-to-race RaceCon configuration. Adapting

the display pages and additional functions is not necessary. If changes are

desired and teams are still unfamiliar with RaceCon, please do not hesitate to

contact customer support at Audi Sport customer racing.

a) Going online with the system

To make changes in the RaceCon project a connection with the car must be

created. This is made via the diagnostic plug at the passenger door.

Some factors can be changed offline in the project and subsequently

downloaded to the car after connecting.

The following data can be changed offline:

-

Views and configuration of the DDU

Lap trigger values

Changes in the logger

900- Electric and Data Acquisition

The following changes can only be made online:

-

Every calibration or adjustment

Adapting the pit speed (after changing the value always copy the WP,

work page, to the RP, reference page)

After connecting to the car, a status LED (green, yellow or red) is displayed for

every component listed in the system tree.

Three green status LEDs indicate that the computer configuration matches the

car.

Changes made offline, for example a modified display view, are highlighted with

the yellow status LED. A message window appears automatically and prompts

whether the values should be adjusted (DOWNLOAD) – DOWNLOAD means that

something is written from the computer to the car.

Example

-

Offline display changed

-> Status yellow

 DOWNLOAD CONFIGURATION

Offline lap trigger changed

-> Status yellow

900- Electric and Data Acquisition

After making changes to the project, which are made online, the configuration

must be downloaded to the car in order to ensure that the computer and car

configurations match.

If the MS6.4-ECU status message is yellow after connecting to the car, this

indicates that changes were made offline, whereby the parameters between

computer and ECU differ.

Afterwards a message asks whether an UPLOAD or DOWNLOAD is desired.

Attention

In this case, a DOWNLOAD should never be implemented, but first an UPLOAD

to load the ECU dataset to the PC. Now it is necessary to make the desired

changes and to copy the work page to the reference page.

The MS6.4-ECU status LED must always be green.

d) Calibration and adjustment

Various elementary functions can or must be adjusted and/or calibrated. For

example, the following variables must be recalibrated after every engine or ECU

change:

-

Throttle pedal (aps) via

CWAPSADJ

CWTHRADJ

CWCAMADAP

 (also if throttle pedal changed)

Butterflies (ath) via

 (also if one or both throttles changed)

Camshaft (cam) via

 (also if a camshaft sensor changed)

Other variables to calibrate:

-

Clutch paddles (aps) left and right via

CWCLPADDLExADJ

 (also if steering wheel changed)

-

Steering angle sensor

CWSTEERCAL

CWDAMCAL

Damper travel (if available)

Attention

No error entries for the relevant interface may appear: E_xxx = FALSE.

Important: When calibrating or adjusting, every calibration and adjustment can

only be made if the ECU is connected (status green). After calibration, the

calibration conditions must always be reset to FALSE and/or ‘0’.

Overview of engine and gearbox temperatures and pressures

Calibration camshaft

-

Run the engine at idle speed; toil > 65 °C

Start camshaft adaptation when calibrating condition 15 is

written in the calibration channel CWCAMADAP and

confirmed by pressing ‘enter’

-

Wait until the adaptation status (cam_adapt_sate_x)

indicates successful for all camshafts

-

If this is not the case, the procedure must be repeated!

Camshaft adaptation is finished when calibrating condition

‘0’ is written in the calibration channel CWCAMADAP and

confirmed by pressing ‘enter’

3.

Calibration linear potentiometer damper (‘define 0’)

-

Set calibrating condition of calibration channel from FALSE

to TRUE and back to FALSE

Calibration throttle pedal

-

Press the throttle pedal to the mechanical stop (full throttle)

– activate status ‘calibrate full pressed pedal’

Release throttle pedal and/or do not press – activate status

‘calibrate release pedal’

Reset status to ‘calibration inactive’

5.

Calibration clutch pedal

-

Pull right clutch paddle to mechanical stop – activate status

‘calibrate full-pulled paddle’

 Do not pull clutch paddle – activate status ‘calibrate

release paddle’

 Reset status to ‘calibration inactive’

-

Pull left clutch paddle to mechanical stop – activate status

‘calibrate full-pulled paddle’

 Do not pull clutch paddle – activate status ‘calibrate

release paddle’

 Reset status to ‘calibration inactive’

Checking / basic adjustment gearbox potentiometer

-

Set the gearbox potentiometer to 1.2 volts when Neutral (N)

selected; see also chapter 901 - 1.1 Checking / Adjusting

Gearbox Potentiometer

Calibration butterflies

-

Activate status ‘automatic calibration’

As soon as the calibration is complete reset status to

‘calibration inactive’

8.

Calibration steering angle sensor

-

Rotate steering wheel 180° to the left – activate status ‘cal

left’

-
