DATA SHEET EVO4

Firstly, we would like to thank you for choo­sing the EVO4 Data Logging System as the
tool for improving your race craft setup and
on-track performance.
The EVO4 system, with its advanced expan­sion and sampling capabilities, gives you
the flexibility of recording data from a va­riety of sensors and sources.
With integrated GPS, a built-in three axis ac­celerometer, and direct connectivity to
hundreds of aftermarket and factory ECUs,
the EVO4 is an exceptional data platform.

As you begin working with your new EVO4
system, we are sure questions will come up.
If they do, please let us know…info@aim­sportline.com. We are all too happy to help!

One more thing before digging into your
new data system…we are constantly wor­king on bettering our software and fir­mware, so please be sure to check the
website periodically for any applicable
software or firmware updates…www.aim­sportline.com

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.

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.

CHAPTER 3 LINKS, SENSORS AND CONFIGURATIONS

You will see this screenshot:

Here are the different EVO4 connection
possibilities:

n

To ECU

n

To RPM signal

n

To speed signal

n

To analog inputs

n

To expansions

n

To the optical lap time receiver

When connecting EVO4 to a sensor, to ECU,
or to an expansion module, you must also
configure it in order to make EVO4 record
the proper data.

In particular, per every channel you have to
define:

n

The connected sensor

n

The frequency acquisition of the sensor

n

The unit of measure

Please use Aim software RaceStudio2
for system configuration.

RaceStudio2
Configuration.

In this chapter it is explained how to confi­gure EVO4 with RaceStudio2 software.

Connect EVO4 to your PC and run
RaceStudio2.

-> Select the button

"Device Configuration"

-> Select EVO4.

1

Press the “New” button and fill in the
required fields.

You must now define the parameters of the
system.

Each point will be explained in more depth
in the dedicated chapter.
