Thanks.
Dear Customer,
First, we would like to thank you for choosing
the MXL2 dash logger as the tool for
improving your racing craft setup and
on-track performance.
The MXL2, with its high contrast display,
advanced expansions and sampling
capabilities, gives you the flexibility for
reviewing your data in your preferred way
and recording them from a variety of
sensors and sources.
Please, before digging into your new data
system, keep in mind that we are constantly
working on bettering our software and
firmware.
So, be sure to check our website
periodically for any updates.

CHAPTER 1
INTRODUCTION MXL2
What is MXL2?
MXL2 is a color, high-contrast brilliant
traditional LCD dash logger developed
for race car installations.
It is fully customer configurable.
Which data does it
manage?
Data come from a wide range of sources,
including your vehicle ECU, the internal
accelerometers and gyro, the GPS
module included in the kit, the
analog/digital inputs, the external
expansions as well as predefined math
channels.
How many pages does
it show?
You can define up to eight different
fully customizable pages.
Is it possible to configure
the pages?
You can choose among a wide library
of page styles, defining the data to be
shown. End of scales and units of
measure can be easily configured,
using the RaceStudio3 software
included in the kit.
How do alarm LEDs
work?
You can configure alarm LEDs
choosing color, blinking frequency and
defining the logic for turning them on
or off.
What is it possible with
WiFi?
You can use a WiFi connection for
transmitting the data of your test,
sending data online and for
configuring the system.
Are the data recorded
by MXL2 compatible
with the old MXL and
EVO4 data?
Yes, MXL used to produce data in DRK
format. MXL2 offers an improved data
management and produces XRK
format that only RaceStudio3 can read.
Nevertheless, the last releases of
RaceStudio2 can detect XRK files and
transform them into old DRK format
files that are compatible with MXL1
and EVO4 files.
What is the difference
between the old DRK
format and new XRK?
XRK, taking advantage of GPS
technology, associates absolute time
and GPS position to each data with the
precision of 1 millisecond.
In this way, it is possible to better
compare different laps and tests.
What about
RaceStudio3?
What are the
differences between
the old DRK format
and new XRK?
RaceStudio3 is the new software for
managing configuration, data
download and data analysis for all the
future AiM systems.
It is going to substitute RaceStudio2,
which has accompanied us for almost
15 years.
Based on a totally new and much more
flexible architecture, it is a work in
progress; some features still have to be
developed, so they are actually shared
with RaceStudio2.
We are going to upgrade it very often,
so, please, don’t forget to check our
web site at www.aim-sportline.com.

MXL2 features 10 RGB gear flash LEDs that
can be freely configured in a very flexible
way. For each LED, you can define the RPM
2 2
value at which to turn it on and the colour.
You can also define different RPM values of
each gear number.

5. ECU connection
MXL2 can acquire data from the ECU of
your vehicle.
The list of the ECU protocols available is
published on our site:
www.aim-sportline.com/download area,
ecus connections.
This list includes approximately 500
different protocols and is constantly
updated with new protocols and upgrades
published every week.
When possible, documents explaining how
to configure your ECU to ensure
compatibility between the data flow
transmitted are available, too.
From an hardware point of view, MXL2 is
compatible with all currently available
connections: CAN, RS232 or K line.
The steps to manage the data coming from
the ECU are the following:
1. Determine which hardware connection
is available for your ECU.
2. Read the documentation about your ECU
at www.aim-sportline.com and identify the
name of the proper software driver to be
specified.
3. Using Race Studio 3, configure MXL2
setting your ECU driver with the menu
shown here below, that appears when you
create a new configuration.
2
MXL2 also has 6 different alarm LEDs that
you can configure in order to turn them on
or off depending on the value of the analog
or digital inputs, ECU values, expansion
values, GPS information or math channels.
You can associate an alarm LED, a message
and a digital output with each event.
10 11
You can configure them in order to turn them
off when the condition disappears, when you
push a pushbutton, when the test is finished
or when the data are downloaded after the
test.
Please, read section 10.1.4 in order to see how
to manage gear flashes and alarm LEDs.
The ECU has to be set when configuring
your MXL2 with RS3 configuration
software.
The steps are explained in section 10.1.
6. RPM
CHAPTER 6 RPM
MXL2
MXL2 can receive the RPM signal from three different sources:
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
6.1 RPM from ECU
To get RPM from the ECU please configure your MXL2 and enable RPM channel as explained
in section 10.1. RPM is one of the many data flowing from your ECU to MXL2.
6.2 RPM via a 5-50 V Square Wave Signal or coil (150-400 V)
In case your engine is not managed by any ECU, MXL2 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 to 50V). The pin labelled "RPM" reported in appendix “Pinout” receives the
signal:
The image shows an example of wiring for
the ignition system.
The output, labelled “GREY TACH” gives a
5-50V output that can be directly acquired
from MXL2 If the output is not available
from the ignition system, the system has to
be connected to the low voltage of the coil,
as shown in the following schematic.

After connecting the RPM signal, please use
the software RaceStudio3 for enabling the
RPM channel, as explained in section 10.1.2
