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.

13
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.

14
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:
http://www.aim-sportline.com/eng/download/index.htm
MXG user guide available on AIM website:
http://www.aim-sportline.com/download/doc/eng/mxs-mxg/MXG_user_guide_101.pdf
Shift lights and alarms:

18
1. On the top of the display there are ten gear flash leds that can be freely configured. The rpm value
at which to turn it on and the colour can be defined. Gear dependent lights can be also defined.
2. On both sides of the screen there are eight alarm leds that can be freely configured. The conditions
to turn them on and off and the colour can be defined. Also messages on a red ribbon in the lower
part of the screen and completely screen pop-up messages can be defined.
Note:
IMPORTANT: the change of the alarms or shift lights is under user responsibility. Car is delivered
with Audi Sport recommendation. Before changing them it is advisable to do a backup of the
standard configuration.
MXG connection schemes
Scheme 1: Data-logger standard connection scheme (car delivery).
Scheme 2: Data-logger connection scheme with Smarty-cam and expansion module (example).
Features
Remarks
Lap-trigger
The MXG system uses only GPS signal.
Circuit
Through the RaceStudio3 software is possible to activate all the circuits in the world.
It is also possible to create and load a new circuit.

19
Extra sensors
In case of adding extra sensors, they have to be connected to an expansion module.
This expansion module has to be connected through the data hub as shown in the
scheme 2.
Notes:
Channel expansion module and sensors are available through AIM dealers, not Audi Sport.
If for any reason it is necessary to send data acquisition files to Audi Sport, following data file
extensions must be sent: .drk, .gpk and .xrk.
