2 DRIVER CONTROLS

In this section, it is explained how the driver can handle the different commands and functions of the car within his range while driving.

Main panel

Function

Remarks

Ignition switch

It activates the power to all devices. The main switch has to be active.

Main switch

It activates the power supply.

Lights switch

It activates the low beam. High beam and flash activation buttons are placed on the steering wheel module.

Blinker switch

It activates the left and right turn lights. A green alarm on the display appears showing that the turn light is blinking.

Brake balance

Turning the balance wheel you can balance the brake pressure from front to rear or vice versa. Do not press the brake pedal while moving the balance wheel. Through the driver display you can check the front and rear brake pressure and the brake balance.

Notes:

 To start the car, always proceed in this order: main switch, wait until display has booted (Audi Sport

logo disappears), then ignition switch.

 The correct procedure to stop the car is the following:

1. Stop the engine using only the yellow switch (ignition switch/KL-15).

2. Wait at least 60 seconds.

3. Switch off the car using the red switch (main switch/KL-30).

 If this procedure is followed correctly the OBD faults memory is saved and these faults can be

checked with the diagnostics tools at any time thereafter. These faults are saved until the memory is deleted manually using the diagnostics program.

The diagnostic tool DiagRA-LE is recommended for customers to be able to check the cars.

Notes:

 The FCY speed can be selected between the following speeds: 40, 50, 60 and 80. The speed can

only be selected with the car stopped following this process: +30 switch ON, +15 switch OFF, keep FCY button pushed and select the speed using the gear shift paddles. The selected speed can be seen on the AIM MXG display.

 The Pit limiter speed can be selected between the following speeds: 40, 50, 60 and 80. The speed

can only be selected with the car stopped following this process: +30 switch ON, +15 switch OFF, keep Pit limiter/Starter button pushed and select the speed using the gear shift paddles. The selected speed can be seen on the AIM MXG display.

 Although it is possible to uncouple completely the steering wheel from the column with the engine

running, it is not advisable (causes fault messages on the OBD).

Speed limiter (Pit limiter/Full Course Yellow/120 limiter)

The speed limiter system allows limiting the car speed at a preselected value. There are five possibilities: 40, 50, 60, 80 and 120 km/h. This system is recommended for the pit lane area or Full Course Yellow (FCY) situations.

Process:

1. Select the desired speeds for each steering wheel button before starting the car and leaving the pits. Only the FCY and Pit limiter speeds are variable, the 120 limiter cannot be changed. The selected speeds are shown on the display.

2. Activate the desired speed limiter with the corresponding button. From this moment on throttle pedal may be fully pressed and the speed will be limited.

3. If the car speed is over the target, the engine torque may be cut. If the speed is below the target, torque will be applied till the speed is reached.

4. Make a short push on the selected speed limiter button on the steering wheel to deactivate the function.

Display alarms and shift lights

Car delivery shift lights and alarms configuration:

 LED 1: continuous yellow: Low oil pressure. If no red alarm follows you can continue. If alarm

disappears you can continue pushing. Check the oil level when back into the pit.

 LED 1: slow blinking green: Left turn light is active.  LED 2: fast blinking red + POP UP: Very low oil pressure. Big risk to break the turbo or to damage

the engine. Audi Sport recommends slowing down and entering to the pit-lane or stopping in a safe place.

 LED 3: continuous purple: Battery voltage low warning. You can continue, check the alternator

and the alternator poly-V belt.

 LED 4: continuous yellow: Fuel pressure low warning. You can continue, check the fuel level.

 LED 5: continuous yellow: water temperature high. Pay attention, drive out of slipstream and

keep an eye on the values. If no red alarm follows you can continue. If alarm disappears you can continue pushing.

 LED 5: slow blinking green: Right turn light is active.  LED 6: slow blinking red: water temperature too high. Drive out of slipstream and keep an eye on

the values. Some torque reductions will appear but you can continue.

 LED 6: slow blinking red + POP UP: Critical water temperature. Audi Sport recommends slowing

down and entering to the pit-lane or stopping in a safe place, to avoid damaging the engine.

 LED 7: continuous white: Gearbox oil temperature high. Drive out of slipstream and keep an eye

on the values. You can continue.

 LED 8: continuous blue: Intake air temperature high. Drive out of slipstream and keep an eye on

the values if not some torque reductions will appear. You can continue.

 LED 8: slow blinking white: Steering initialization needed (it will appear each time the car is

switched on). Turning the steering wheel left and right should disappear. If not, there is a problem in the electrical steering rack.

 LED 1 + LED 5: slow blinking red: Pit limiter is active.  LED 1 + LED 5: slow blinking yellow: Full Course Yellow is active.  LED 1 + LED 5: slow blinking blue: 120 limiter is active.  LED 4 + LED 8: fast blinking green: Hand brake is locked and engine started. Unlock it before

trying to move the car.

 LED 4 + LED 8: fast blinking green + POP UP: Hand brake is locked while you are driving. Audi

Sport recommends unlocking the hand brake and entering to the pit-lane to check if the rear brake callipers have been damaged.

Note:

 It is possible to customize the alarms and shift lights through the RaceStudio3 software installed

on a laptop.

Gearbox functioning

R - Reverse mode:

 It is possible to put on this R mode if the car is complete stopped and clutch pedal pressed.  In case of clutch pressure sensor malfunction, it is also possible to use the steering wheel (P) Safety

brake signal button to put on or take out the R mode. IMPORTANT: the use of this button is under user responsibility, a bad use of it may cause fatal damages on the gearbox.

N - Neutral mode:

 In N mode, it is possible to move the car pushing externally (pit lane use).  To enter into this mode it is mandatory to press the clutch pedal.  To exit from this mode it is necessary to be completely stopped and pressing the clutch pedal.  It is also possible entering to and exiting from this mode using the steering wheel (P) Safety brake

signal button. IMPORTANT: the use of this button is under user responsibility, a bad use of it may cause fatal damages on the gearbox.

Driving mode:

 It is possible to go from N to 1st gear if the car is completely stopped and the clutch pedal is pressed.

Also possible using the steering wheel (P) Safety brake signal button. IMPORTANT: the use of this button is under user responsibility, a bad use of it may cause fatal damages on the gearbox.

 It is possible to put on Neutral mode at any moment only if the clutch pedal is pressed.

 It is not necessary to use the clutch while shifting on the track, only to start from standing position.  Once the vehicle is moving use the steering wheel paddles to upshift or downshift.  Remember that the shifting is only manual, when the engine reaches the rev limiter (6800 rpm) the

power is limited but no automatic upshift will happen. To stop the car it is necessary to press the clutch pedal to avoid engine stalling.

 Downshifting is protected preventing the engine from over-revs. If there is a downshift demand at

too high revs the gearbox will not do it. There is no memory function.

Parking mode:

 Use the Neutral gearbox mode and lock manually the hand brake using the locking hook. The

gearbox will not be locked, only the car due to the rear brake pressure generated by the hand brake pump.

 To unlock the car just remove the hand brake hook.  To lock the transmission completely, stop the car on 1st or R gear.

3 ELECTRONICS

AIM MXG

MXG is the AIM dash-logger designed to acquire and display in FHD data coming from your ECU, the internal accelerometer and gyro, as well as from the GPS module, analog/digital inputs and predefined math channels.

Downloading data can be done through a data download cable, a memory stick or using the available Wi-Fi features.

Performance and data acquired can also be incremented adding expansion modules. Using the specific AIM on-board camera SmartyCam it is possible to overlay on videos the data sampled by the logger.

To see the lap times it is necessary to insert the track where you are running. Track load has to be done by the RaceStudio3 software.

RaceStudio3 software, latest MXG firmware and documentation available on AIM website:
