INTRODUCTION
What is EVO4?
EVO4 is a complete, compact and
expandable data logger, suitable for
installation on both car and motorcycle.
What data reads?
EVO4 acquires:
5 analog inputs, at a configurable frequency from 1 to 1000 Hz per channel.
These signals can be: 0-5 Volt, 0-500
mV, 0-50mV, thermocouples K.
2 digital inputs, suitable to receive signals from speed sensors.
1 RPM input, suitable to receive
signals from low voltage of the coil or
square wave 0-12 Volts.
Data coming from internal triaxial
accelerometer.
Data from the internal GPS with
external antenna.
Data coming from the engine control unit (ECU). There are three
hardware protocols available:
CAN, RS232 and Linea K.
Hundreds of ECU are fully supported.
The lap time transmitted from the
infrared receiver.
The internal temperature of the
system.
What is the
maximum frequency of
acquisition possible?
It is possible to acquire signals at a
maximum total frequency of 5000
samples per second (i.e. 5000 Hz).
How much
memory is available?
EVO4 has 16 MB of non-volatile
memory capable of recording more
than 4 hours of data at a total frequency of 500 samples per second.
To what purpose you
can use the GPS?
The integrated GPS is useful for
different purposes.
Lap time calculation:
A large database of world tracks are
avaliable.
The coordinates of the finish line are
available for meny world tracks.
When turned on, EVO4 recognizes
which track you are at and uses the
coordinates to calculate the lap time
with high precision.
Measurement of the speed of the
vehicle:
In contrast to the measurement of the
wheel speed, the speed measure
based on GPS signals is not affected by
the variation of the size of the wheel
(due to the centrifugal force, the crushing and, in case of bikes, the inclination of the bke itself) and is thus more
precise.
Analysis of the trajectories:
GPS receiver is an important tool to
properly calculate the trajectory at
every single lap and then to compare
the different driving strategies.
Which displays can be
connected?
EVO4 can be connected to the following dashes:
GDash
MXL Dash
Formula Steering Wheel
GT steering wheel 32/35
Which expansion
modules are available?
EVO4 can be connected to the
following expansion modules (max.8)
Channel Expansion: 4 additional
analog channels 0-5 Volt. You can add
up to 7 channel expansion.
TCHub: 4 thermocouple channels.
LCU-One Lambda Controller
Memory Module: memory module
with additional SD card.
SmartyCam: the powerful camera
with data overlay.

CHAPTER 2
Power.
Power is provided by connecting the appropriate cable to the battery of your vehicle. It is not
necessary to use special attention, because there is a stabilizer that regulates the internal power
supply used by the system.
So you can connect EVO4 without any problem to a NOT stabilized power source from 8 to 24
Volts. Even shutting down the system does not require special attention: when the power is
turned off, a small battery in the system keeps the internal power supply on for a few seconds
in order to properly close the internal data files.
If your power is too spiky, an external power filter (code X60FLCEVO4), is available.

CHAPTER 2
GENERAL INFORMATION EVO 4
Data Recording.
EVO4 is equipped with a 16 MB circular
memory *, capable of recording 8 million
samples.
The test length that can be recorded
depends on the sampling frequency
(i.e. how many channels per second are
recorded).
For example, in case your acquisition has a
global frequency of 500 Hz, which is fairly
common, the system can record almost 4
hours of testing.
If you require larger memory, the external
Memory Module is available: it can manage
a SD Card up to 16 Gygabyte SD and can
provide virtually unlimited recording capability.
*
"Circular buffer" means that once it reaches saturation,
the oldest data are overwritten by the most recent

Start/Stop Recording.
EVO4 starts recording when one of the
following situations persist for more than
three seconds:
n
RPMs over 500 rpm threshold
n
Speed over 10 km / h
Thanks to a pre-buffers, EVO4 records also
the three seconds before the engine starts.
Data Download.
After activating the Aim software Race Studio2, the data are transmitted to the PC
using the USB cable supplied with the product.
If you have recorded the test on the Memory Module, you can directly insert the
SD card into your PC.
At the end of the data download, you can
delete the data in EVO4 or leave them in
memory, to eventually download them to
another PC.

ECU Connections.
CHAPTER 4 ECU CONNECTIONS
EVO 4
EVO4 can acquire data from all the ECU published on the list on our website:
http://www.aim-sportline.com/pages/download/section_documentation_ecus.htm
This list includes about 500 different protocols and is constantly being updated, since all the
ECUs are often improved and new models appear. When possible, we have explain how to configure your ECU to ensure compatibility between the data flow transmitted and what the protocol is designed to manage.
From the hardware point of view, EVO4 is compatible with all currently available connections:
CAN, RS232 or line K. If you need a CAN or RS232 connection, you must connect the cable to
the connector labeled "ECU"; if you have to use the OBDII K Line, please use the connector labeled "rpm / K".
The steps to manage the data coming from the ECU are:
n
1. Determine which hardware connection is available for your ECU.
If your ECU transmits the data to CAN or RS232, you need to connect the cable 04.563.01
(Shown below left) to the connector labeled ECU.
If it is equipped with a K line, you must use the cable 04.563.05 (shown below right) and
connect to the connector labeled "rpm / K".
n
2. Please read the documentation about
your ECU in www.aim-sportline.com, and
identify the name of the proper software
driver.
n
3. Configure EVO4 setting that software
driver in RaceStudio2. (1)
n
4. Select the channels to be recorded.
n
5. Send the configuration to EVO4. (2)

The RPM Channel.
CHAPTER 5 THE RPM CHANNEL
EVO 4
EVO4 can get the RPM signal in many
different ways:
n
From ECU
n
Through a square wave signal (8 to 50 V)
n
From the low voltage (from 150 to 400 V)
of the coil.
n
From the spark plug by converting the
inductive RPM signal read from the spark
plug into a square wave signal.
In this case you must use an optional
RPM adapter Code X10ADRPM000.
n
How to read RPM from ECU
To get RPM from the ECU, connect EVO4,
configure it as shown in the previous paragraph and enable RPM acquisition from
ECU.
In this case, RPM is of course just one of the
many data flowing from your ECU to EVO4.
n
Acquiring the RPM via a 5-50 V square
wave signal or coil (150-400 V)
In case your engine is not managed by any
ECU, EVO4 can read the signal from the low
voltage of the coil (whose peak can be from
150 to 400 V) or from a possible square
wave (the peak can be from 5 at 50V.)
The connector labeled "rpm / K", reported
in Figure 13, receives the signals:
The connection cable is in the kit and its
code is 04.563.02.
You will find the technical drawing in the
Appendix.
The following image shows an example of
wiring for the ignition system. The output
cable, labeled gray tach, which can be acquired directly from EVO4 through the 5-50
volts. input, is shown here:
n
Low coil voltage 150-400 V on Pin 1
n
4-50 V square wave on pin 3
22
123
CHAPTER 5 THE RPM CHANNEL
EVO 4
If an output is not available from the ignition system, the system has to be connected to the low voltage of the coil.
The coil from which to get the signal, is
schematically shown in the image below.
n
Point 1
Is the low voltage input of the coil.
n
Point 2
Is connected to the spark plug.

CHAPTER 5
THE RPM CHANNEL
EVO 4
In order to properly configure EVO4 using
the control panel you must:
n
Ensure AIM sensor is selected.
n
Define "max RPM."
n
Select the possible multiplication factor
(RPM factor).
Its value is typically 1 for two-stroke engines and four-stroke multi-cylinder, and 2 for
single-cylinder four-stroke engines.
n
When the RPM signal is noisy
Sometimes the signal from a low voltage
point 0-50 V of the coil is particularly noisy
and EVO4 does not read RPM properly, as
in the examples:
Dirty signal from the coil Filtered wave signal
Dirty signal from the ECU
26
In such cases, the filter shown in Fig.17 (Code X05ADRPMM30) can be useful. The input of the
filter must be connected to the signal RPM, and the output to the input square wave EVO4 for
5-50 V (pin 3 of connector rpm / K).

The Speed Channel.
CHAPTER 6 THE SPEED CHANNEL
EVO 4
EVO4 can receive the speed signal from
three different sources:
n
The ECU
n
The Built - in GPS receiver
n
The two digital channels
It is possible that EVO4 receive and store
different values of speed at the same time:
the more powerful ECUs transmit up to four
wheel speed values; considering speed values that come from GPS and from the two
digital channels, there may be 7 different
speed values.
*Note that even if EVO4 can read and record up to seven values of speed, only ONE
of these is used for some special functions,
such as:
n
Gear calculation
n
Distance measurement
n
Data visualization in analysis software
This speed is called “Reference Speed”and
is defined in the software RaceStudio2.
n
Speed read from ECU
If your ECU sends the value of speed in its
data stream, it is possible to read, record
and show that information.
Simply enable the channel in RaceStudio2
and set define this speed as "Reference
"
Speed.
ECU - CAN - RS232 GPS Output
Speed 1-2
n
Speed read from GPS receiver
The GPS receiver integrated in EVO4 is configured in order to obtain the best performance in terms of reactivity and accuracy.
We know that GPS signals are extremely
weak, only 20 watts, and are transmitted
from satellites at 20.000 km away.
Data accuracy can therefore sometimes be
not as good as we would like.
However, we can say that it is generally
more than satisfactory and that GPS speed
is very often better than wheel speed.
28
GPS Antenna
129
n
Speed read from the wheel
EVO4 has two wheel speed inputs, in the
same "speed" connector:
The digital sensor X05SNBS00 detects the
presence of a metallic tooth placed at a distance between 0.5 and 2 mm.
CHAPTER 6 THE SPEED CHANNEL
n
For configuring wheel speed
parameters.
Enter the Program Configuration panel and
after enabling the channel desired speed
(speed 1, speed 2 or both), set the wheel
circumference and the number of pulses
per revolution:

It will allow you to select nations, the type
of vehicle and type of circuit.
The lists show only countries, vehicles and
types of circuit present at least once in the
database.
For example, if you have not used any track
in Germany, this country will not appear in
the list.
By default all countries, types of vehicle and
tracks are abilited.
n
Dynamic Filters.
The Dynamic filters are activated in the box
at the top left of the screen:
The dynamic filters allow you to further filter the tracks (in fact the car) merging different characteristics.
For example, writing "Spain closed," you will
see only closed circuits for cars in Spain.
If you are interested in only the car tracks,
for example, you must disable karts and
motorcycles.
