MyChron5
Twenty years ago we installed the first
MyChron…
The original simple concept of a personal
chronograph automatically showing lap times
and other important information to the racer
has remained the core of the system, that, in
the meantime, has improved and improved till
arriving to the now borning Fifth Generation.
Introducing now MyChron5, we are deeply
grateful to all of you, that have followed us
during all this time, in all the tracks of the
world, in every category, in every country.
We are deeply grateful to all our dealers,
distributors, friends that have spent their lives
on the track, attending our systems, helping
everybody to start using them, repairing them
when they required to be repaired, giving us
the important feedbacks that allowed us to
improve them constantly in all these years.
Thank you.

1. MyChron5 in a few
words
MyChron5 is a gauge designed for
being installed on a kart.
02 03
It reads and records:
n RPM at high frequencies (up to 50
times per second) from the spark cable
n One or two temperature values
(depending upon the model).
They can be exhaust gas, underspark,
or water temperatures.
n All parameters coming from the
GPS/Glonass costellations: speed,
position, lateral acceleration and time
of day with precision of one
millisecond.
The receiver has been tuned for our
sport, so it accepts all the strong lateral
and linear accelerations, change of
direction and vibrations without any
problem, always giving a perfect result
ten times per second.
MyChron5 uses the GPS and Glonass
data for calculating lap time. It comes
with more than 1500 tracks in the inter-
nal database, so it automatically reco-
gnizes the track in which you are
racing, it knows the position of the
starting line and eventually of the split
points and can calculate the lap/split
times with a high precision.
All these data are recorded in a huge
4GB internal memory, enough for re-
cording your data for thousand of
hours.

Power comes from the internal battery
or, as an option, from the external
power supply. The battery is included.
It is a huge, removable three-amp
lithium ion rechargeable battery,
which comes with a battery charger.
It may give power to your system for
ten hours.
MyChron5 is e pandable: you can
connect to the CAN bus:
- SmartyCam HD
- Lambda Sensor
- MyChron Expansion
The display is a wide LCD display with
an RGB backlight that you can easily
configure.
By the way, the backlight
automatically turns on when the
ambient light is low, thanks to a
dedicated light sensor.
There are two RGB alarm LEDs: you can
configure the color, blinking frequency,
and event to which to connect them.
There are five RGB shift lights for gear
change, better monitoring of RPM, or
lap time indications.
Then, you can analyze your data using
the worldwide, well-known RaceStudio
software, freely downloadable from
our website.
You can download your data to your PC
using a WiFi connection.

"Do not run the RPM lead in any type of tubing; it should be run
right along the frame rail.
Take care not to overtighten the tie wraps. If your lead is too
long, don't coil it up; just cut the tach end to length.
At the tach end, make sure that the lead loops through the two
small holes and then extends out about half an inch and then
use a small tie wrap to keep it snug.
It is very important to pull the RPM wire about four inches through one side of the clip then
wrap the wire around your plug lead a couple of times and back through the opposite side of
the clip."
A clean RPM signal is key to good performance from your MyChron. To get a clean
signal, it's important that the RPM lead be installed correctly in order to pick up a
strong signal from the plug wire.

The lap setup brings you to the following page:
Lap show time can change between:
n static
n rolling
n - +/- best
n predictive
RPM frequency: RPM can be read 20 or 50 times per second ( 20 or 50 Hz), in dependence upon
your necessities:
20 samples per second let you have a cleaner signal, and make easier to see the RPM trend,
while 50 samples per second let you better recognize the vibration of the chassis and all the
strengths that can create problems to the ideal movement of your kart.
In the above picture you can see both data, at 20 and 50 Hz, in order to note the differences in
acquisition.

Your MyChron5 comes with the information about a good number of kart tracks
already available in it.
Our technicians are constantly working to upgrade the database, and new releases
of it are freely downloadable using the Race Studio 3 software.
If you need to upgrade the track information in the gauge, please refer to chapter 9.
After selecting the Tracks icon, you enter into the Track Selection Menu:
MyChron5 offers two selection modes:
n Automatic: MyChron5
automatically recognizes the track in
which you are running, gets the
coordinates of the starting line and,
eventually, of the magnetic strips and
is ready for calculating lap and split
times without the magnetic/optical
receiver.
This mode is to be preferred most of
the times.
n Manual: Allows you to select the
desired track from the internal data-
base.
The manual mode is to be preferred
when there are different track
configurations nearby.
In this case, the MyChron5 would
anyway understand in which circuit
you are racing, but it would require at
least one lap. If you wish to have
everything set from the first lap, the
manual mode will help you.
If you select the manual mode, you
have to select the track. Click on Track
Selection, and this page will appear:

The GPS receiver inside your MyChron5 is very useful for a good amount of reasons:
n Lap Time calculation
n Speed calculation
n Predictive lap time calculation
n Position on the track analysis
n Lateral g-force calculation
Clearly, for a proper calculation of these information, the system needs to have some
information about the track:
n coordinates of the starting line
n coordinates of the eventual magnetic strips
n length of the track

The tracks in the dbase are shown in the upper part of the display. The nearest are
shown first. You will see the name of the track, the shape, and the distance from where
you are. In the lower part of the track, the selected track is shown.
Please, note that, in case you run on a kart track that is NOT described in our track
database, MyChron5 enters into an "Apprentice mode", doing the following steps
n It starts recording the different points of the track
n As soon as it realizes that it is passing from a point where it has already passed by,
it understands that the circuit is closed and sets a temporary Starting Line, showing
the lap time every time the kart is passing from that point.
n This new map can then be stored into the MyChron5 database and the starting
line coordinates can be eventually modified.
The name of the track can be added too and it can be transmitted to the PC at the
first PC-MyChron5 connection.
4.4 WiFi Setup
Please select the WiFi icon and enter the WiFi setup page.
There are two sets available:
n WiFi mode
n WiFi reset
WiFi mode has three options: on, off, and auto.
In auto mode, the MyChron5 turns the WiFi module on when the kart is not moving
and turns it off when the speed is higher than 10 km/h.
In on mode, the WiFi module is always active, while in off mode, it is always disabled.

Some pages are available for the online data visualization. You can scroll them by
pushing the VIEW button.
Depending on the configuration of your MyChron5 (gear presence, expansions,
SmartyCam connection), the pages may change.
At least three pages are always available:
n Track Selected Page:
This is the page that appears as first, when you turn your MyChron5 on. When the
kart is moving, it automatically disappears and is not available.
It shows:
nOn the left, the map track is selected. It is possible to select a different track ma-
nually (menu/tracks) or automatically.
n On the right, the satellite signal bars show how many satellites are visible and the
level of each signal.
In the lower part of the display, a row that will disappear during the test shows:
n GPS status
n Serial number.
This information is useful if you wish to connect your MyChron5 to your PC via WiFi.
n Time of the day
n Bar Graph Page:
It shows:
nThe RPM bar graph. The range is set in the SET PARAMETER page.
n RPM value on the right of the display

MYCHRO 5
WiFi connectivity is disabled by default in your MyChron5 and must be enabled on
the device menu.
Your MyChron5 can be configured for WiFi communication in one of two ways:
When a MyChron5 is working in WLAN mode, there are two layers of security available:
n Network authentication: the network password
n Device authentication: a unique device password
Using both network and device authentication allows for various security strategies
where multiple people, PCs, and AiM devices are involved. For example, a PC on a
WLAN may see several AiM devices but can only communicate with the AiM devices
for which it has the password
7. WiFi Configuration
1) As an Access Point (AP)
This is ideal when you have one device and one computer.
In this configuration, your AiM device creates its own WiFi network, which acts as an
AP to which you can connect with your PC.
2) To join an Existing Wireless Local Area etwork (WLA )
This is more complex and requires an external AP but is more flexible and powerful.
In this way, you can communicate with more than one device and with more than
one PC on the same network.
In this configuration, both your MyChron5 and your PC have to join a pre-existing
WiFi network, called a WLAN, in order to communicate with one another. The network
is now created by a network device, which is acting as an external AP by permitting
the device’s connectivity.

CHAPTER 7 WIFI CO FIGURATIO
30 31
MYCHRO 5
Follow these steps to create an AP,
allowing you to connect your PC to
your MyChron5 via WiFi.
This is the most simple and direct WiFi
connection method and is ideal when
you wish to communicate with only
one MyChron5 using one PC.
Your MyChron5 as a default, is configu-
red as an Access Point and creates a
network, without a password,
completely accessible to everyone.
So, for establishing the WiFi
connection:
n be sure your MyChron5 has the WiFi
enabled
n read the name of your MyChron5,
available in the lower row of the
OnLine Page:
n click on the WiFi Icon of RaceStudio3
and select your MyChron5:
In a few seconds the communication will be established.
For setting other parametersIt is therefore recommended that you create a unique
password to secure your device/network immediately. With the use of a password,
the communication is secure and encrypted using the WPA2-PS standard

MYCHRO 5
The name of this AP, or SSID, is unique to your device.
An example name is:
“AiM-M5-054321"
Whereas:
n “AiM” is the prefix for all AiM devices;
n “M5” is type of system identifier; and
n “054321” is a unique serial number for your device assigned at the factory.
To make your device more recognizable, you can append a friendly name to the SSID.
There is a limit of eight characters.
For example, if you add the driver's name, Tom Wolf, the resulting network name
(SSID) will be:
AiM-M5-054321-Tom Wolf
After having set all the parameters, click the Transmit and Restart button.
Your MyChron5 will restart and be configured with the new parameters.
To connect to your MyChron5, simply choose your device’s name from the dropdown
list of available WiFi connections from within Race Studio 3.
If your MyChron5 is protected by a password, as recommended, Race Studio 3 will
then require that password to authenticate.
Please note that it is also possible to make the same WiFi connection using the WiFi
tools of your operating system.

MYCHRO 5
Once the WiFi authentication with the device has been established, users can interact
with the device by clicking on it.
In this scenario, both your MyChron5 and PC join an existing WiFi network (WLAN).
This scenario is ideal for a race team with multiple drivers and crewmembers and it
is desired to communicate with one or more AiM devices using the same PC network.
Note again that each MyChron5 can have a unique password, which is in addition to
the network password, thus adding an additional layer of privacy and security.
Race Studio 3 will display any and all MyChron5 devices connected to the same
network as the PC. Connected devices can be seen under the Connected Devices
header, just as if they were connected via USB: simply click on your device in the left
pane under Connected Devices. Go to the WiFi configuration tab and set the mode
to Existing Network.
Then, enter the network password and the device password, should you choose to
add one, in the appropriate fields.
To commit the network settings to your device, click the Transmit and Restart button
on this same tab. Your device will restart and join the network you specified.
Connect your PC to the same network, and you will see your device under Connected
Devices, just as when connected via USB.
If the AiM device is connected to your PC using a WLAN, it is possible to have two
different passwords: the device password, which was already described, and the
network password.
Please note that only passwords following the WPA2-PS code are admitted.
