3.3 – Installing the phonic wheels, the front speed sensor and the related brackets
To install the phonic wheels, the front wheel speed sensor and the related brackets follow these instructions:
• Install the magnetic “Phonic” wheels coaxially to the front wheels.
• Install the brackets on the wheel hub and then install the speed sensors supplied with the kit.
• Using a locking nut system, adjust the distance between the head of the sensor and the magnets. Optimum distance is between 8 and 15 mm (max).
• After sensors installation stretch the speed cables on the anti-vibration mountings.
It is suggested to protect the cables with a spiral girdle (not included in the kit).
• Insert the speed sensors connectors in the chassis using the hole located on the right of the oil brake pumps.

3.4 – Installing the phonic wheels, the rear speed sensor and the related brackets
The kit allows the user to add two speed sensors (not supplied) on the driving wheels. In the digital harness (22 pins) is a dedicated connector, labelled as “rear speed”, to be placed in the left side of the vehicle body.
The channels dedicated to this measure are labelled as Speed_3 and Speed_4.

Manuale di installazione
Versione 1.02
The lap receiver (beacon) is to be installed as shown above. It is recommended to pay particular attention to the following steps:
• Place the receiver “eye” so that it sees the transmitter installed on the border of the track.
• Use ® to fasten the receiver.
• Make a hole on the front fairing in correspondance of the receiver “eye”; hole minimum diameter should be 8 mm (20 mm suggested)
• Connect the receiver to the digital wiring (22 pins) lap connector
Note
: depending on the track direction of travel, the receiver may have to be installed on the other side of the vehicle.

4 – Connections to the vehicle
The connection to CAN bus CAN 1, that allows the communication with Magneti Marelli
MF4-L ECU, is made through J59 connector of EVO3 Pro digital harness, placed in the left side of the vehicle body. J60 connector, on the other side, sends the “end lap” signal to the vehicle dashboard.
To enter the cell on the left side of the vehicle it is suggested to use the passage placed under the left radiator. We would suggest to remove the radiator to clear the passage.
Once reached the vehicle body, it is suggested to use the proper cable passage situated near to the battery on the left side of the vehicle, as shown in the figure below.

Appendix “B” – GPS Module
Warning:
EVO3 Pro data download is available only from Race Studio 2.21.20 onwards.
When a test made using GPS Module is loaded, some new channels are automatically added to “Measures and laps” toolbar of Race Studio Analysis software, to say:
Speed;
• GPS
LatAcc;
LonAcc;
Slope;
Heading;
Gyro;
GPS Speed
Indicates the speed measured through GPS signals.
GPS Nsat
Indicates the number of satellites received during the test. Max number of satellites used to compute GPS solutions is 9.
GPS Lat Acc
This channel shows lateral acceleration compared to the trajectory computed from GPS speed on the three axis.
GPS LonAcc
This channel shows the longitudinal acceleration compared to the trajectory calculated through GPS speed on three axis. It shows accelerations and braking G-forces.
GPS Slope
This channel measures positive and negative slopes of the track.
GPS Heading
This channel measures the heading of the vehicle compared to the North direction.
GPS Gyro
This channel measures the cornering speed of the trajectory in degrees/second.
