7.3 Speed read from wheel sensors
EVO4S has two wheel speed inputs: to
connect two speed sensors use the proper
split cable with part numberV02549030.
The digital sensor X02SNVM00 detects
the presence of a metallic tooth placed at
a distance between 0.5 and 2 mm.
Please use the software RaceStudio3 for
configuring the system.
Just enter the program configuration panel
and, after enabling the desired speed
channels, set the wheel circumference and
the number of pulses per revolution.
7. Speed
EVO4S can receive the speed signal from
three different sources:
n
from the ECU
n
from the GPS receiver included in the kit
n
from the wheel sensors (digital channels)
It is therefore possible for EVO4S to receive
and store different values of speed at the
same time; the more powerful ECUs
transmit up to four wheel speed values.
7.1 Speed read from the ECU
If your ECU sends the value of speed in its
data stream, it is obviously possible to read,
record and show that value.
Simply enable it using RaceStudio3
software, as explained in section 10.1.1
7.2 Speed read from the GPS receiver
The GPS receiver you find in EVO4S kit is
configured in order to obtain the best
performance in terms of reactivity and
accuracy.
For getting GPS speed, you don’t need
any configuration.
Simply connect the GPS Module to your
EVO4S and after a setup period of some se-
conds, the data will be received and auto-
matically recorded.

EVO4S has 5 analog inputs, recorded up to
1000 times per second each.
You can connect:
Please use the following steps, using the
software RaceStudio3 as explained in
section 10.1:
n
connect the sensor to the desired input
n
enable the channel in the Channels table
n
select the proper sensor type; sensors of
many different types are properly handled
n
set the sampling frequency
n
set the unit of measure.
