2 DRIVER CONTROL
In this section, it is explained how the driver can handle the different commands and functions of the car.
Main panel2.1
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.
Turn indicator:
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
back 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 balance in percentage.
Notes:
To start the car, always proceed in this order: Main switch and later 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. If the waiting time is lower, the OBD faults memory is not saved.
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 diagnostics tool DiagRA-LE is recommended for customers to be able to check the cars.
Steering wheel module2.2
The electronic steering wheel module permits
activating different functions without removing hands
from the steering wheel.
Some buttons have double functionality.

Display alarms and shift lights2.3
Car delivery alarm configuration:
LED 1 yellow alarm light: 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 2 red alarm light + POP UP: Very low oil pressure. Big risk to break the turbo or to damage
the engine. Seat Sport recommends slowing down and entering to the pit-lane or stopping in a
safe place.
LED 3 purple alarm light: Battery voltage low warning. You can continue, check the alternator
and the alternator poly-V belt.

12
LED 4 yellow alarm light: Fuel pressure low warning. You can continue, check the fuel level.
LED 5 yellow alarm light: 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 6 red alarm light: 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 red alarm + POP-UP message: Critical water temperature. Seat Sport recommends
slowing down and entering to the pit-lane or stopping in a safe place, to avoid damaging the
engine.
LED 7 white alarm light: Gearbox oil 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 blue alarm light: 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 red alarm light: 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.

Gearbox functioning2.4
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.
D - 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 paddle-shift to upshift or downshift.
The shifting is manual. When the engine reaches rpm limit (6800 rpm) the power is limited and to
stop the car is necessary to press the clutch pedal to avoid engine stalling.
Downshifting is protected preventing the engine from over-revs. If there is a down-shift demand at
too high revs the gearbox will not do it.
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.
Standing start procedure2.5
Start rev limiter:
This system is automatically and only activated if wheels are absolutely stopped. The throttle pedal can be
fully pressed and engine speed will be limited at 4200 rpm until the car starts moving.
There are many ways to manage standing starts; following the SEAT Sport recommendation is explained.
Process:
1. After the grid formation lap, stop completely the car on the grid line pushing clutch and brake
pedals.
2. 1st gear has to be engaged.
3. Use the hand brake to keep the car stopped and release the brake pedal.
4. When the red starting lights begin, maintaining the clutch pedal fully pressed, push gas pedal flat
out. Engine will limit at 4200 rpm.
5. Preload the car releasing the clutch slowly while you keep the car stopped with the hand brake.
6. When the red light turns off, release the hand brake and control the start with clutch and throttle
pedals. Once the car starts moving the rev limiter will disappear so be careful to avoid engine stall
and wheel spin.
Notes:
Is possible to start at lower engine speed without using the start rev limiter, just get the desired
engine speed playing with the throttle pedal. Advisable no bellow of 3500 rpm.

14
Take care of the time you are keeping the engine preloaded at 4200 rpm. The clutch and the
engine may take temperature very fast. Recommendation no more than 6 seconds of start rev
limiter use.
Speed limiter (Virtual Safety Car)2.6
The speed limiter system allows limiting the car speed at a predefined value. There are five possibilities:
40, 60, 80, 100 and 120 km/h. This system is recommended for the pit lane area or Virtual Safety Car
(VSC) situations.
Process:
1. Select the speed using the green button on the steering wheel. The is shown on the display.
2. Make a short push on the red starter button on the steering wheel to activate the function at the
previously defined speed. 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 red starter button on the steering wheel to deactivate the function.
Note:
It can be applied in different gears.
Driver has to consider2.7
Learning and memorizing the steering wheel buttons placements and functions will allow drivers a
faster action and will help them to keep focused on the track.
Warm up the engine before starting. The minimum water temperature recommended before
loading the engine is 80°C.
Check the brake pedal stiffness when car is stopped or on the acceleration way.
Warm up tyres before attacking. Without blankets use, the rear tyres may need 2 laps to get
warm and the car is very sensitive to this.
Shift up gears when shift light indicates. The shifting lights have been optimized taking into
account gear ratios and engine power.
Shift down gears without stress. If a downshift is required at too high revs it will be electronically
rejected at it will not happen.
In-laps: cool down brakes and engine water to avoid thermal shocks.
There are three different possibilities to show alarms on the display: lateral leds, messages on a
red ribbon in the lower part of the screen and complete screen pop-up messages. If a pop-up
message appears is strongly recommended to stop the car.
If for any reason it is necessary to drop out the car on the track, leave the gearbox in neutral to
save the transmission in case of being towed.
It is important to bed discs as follows to get their maximum life:
oWhen possible bed discs with used pads.
oTo reduce thermal shock during bedding, the brake ducts may be 50% taped off.
oApply the brakes gently at low speed a few times to ensure a correct installation.
oApply the brakes moderately, (progressively up to 50% race speed, 25% race pressure), for
10-20 applications to ensure above 80% pads face contact with disc. The contact with the
disc face is particularly important at the inner swept area. The first time a driver gets used to
bedding discs on a car it is worthwhile getting him to return to the pits to check contact is
sufficient before preceding to the next step.
oProgressively build up to about 70% of race speed and 50% of race pressure. Then, apply
brakes for approximately 25 applications.
oPerform one lap cooling down before returning to the pits.
oWhen returning to the track, come up progressively to race speed and pressure.

3 ELECTRONICS
AIM MXG3.1
MXG is the AIM dash-logger designed to acquire and display data coming from your ECU, the internal
accelerometer and gyro, as well as from the GPS module, analog/digital inputs and predefined math
channels.
Performance and data acquired can also be incremented adding expansion modules.
To enable “the lap time” is necessary to insert the track where you are running. Track load has to be done
by the program GPS Manager available at the RaceStudio3 software.
SmartyCam: The on-board camera that overlays on videos the data sampled by your logger.
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

16
Shift lights and alarms:
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.
Notes:
IMPORTANT: the change of the alarms or shift lights is under user responsibility.
MXG connection schemes3.2
Scheme 1: Data-logger standard connection scheme (car delivery).
Scheme 2: Data-logger connection scheme with Smarty-cam and expansion module.

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.
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 SEAT Sport.
If for any reason it is necessary to send data acquisition files to SEAT Sport, following data file
extensions must be sent: .drk, .bak, .gpk, .rrk and .xrk.

Fusebox3.4 Fuse box LED label
The fusebox is an electronic box that controls the power supply to practically all
devices. Internally, the thermal fuses reset automatically, so changing a fuse will
never be necessary. In case of malfunction it has to be sent to SEAT Sport.
It is also possible to check if a fuse has blown in the fusebox, so you will know if
the current or signal was sent.
There are three ways to check the correct functioning:
Live measures view in RaceStudio3.
Checking the fusebox control channels in Race Studio Analysis.
Checking the red LEDs on the fusebox.
If a malfunction is detected, it is necessary to control the corresponding wiring or
the device.
In the following table is shown the fuse analysis information:
Channel name: There are 5 channels to analyse.
Bit number: Each channel is able to control 8 fuses.
Data value: Is the value you can check on data acquisition.

Example:
In the acquisition screenshot bellow is shown the channel “FLAG_FBX_1” in green. The value is
“7” when braking and 0 when no braking. In this case, the conclusion is that there is a problem on
the brake light line.
