The RPM Cable
This clip wire is designed to be plugged directly on the spark plug wire and it is
used for RPM pick up from monocylinder 2-4 stroke engines.
When running the RPM cable along the chassis between the MyChron 3 display
unit and spark plug wire, the RPM cable should be positioned as far as possible
from the thermocouple wire.
9
The Thermocouple
MyChron 3 supports one temperature sensor. There are 4 types of
thermocouples ( temperature sensors ) that are available for selection or
subsequent purchase:
1. H
2
O - Water thermocouple1/8 inches type.
2. H
2
O - Water thermocouple M5 type
3. EGT - Exhaust gas thermocouple
4. CHT - Cylinder head thermocouple
All Aim thermocouple are K-type sensors.
Thermocouple from 2 to 4 are provided with an extension cable ( length = 1.5mt =
45 inches ) Thermocouple 1 doesn’t need extension wires ( length = 1.5 mt =
45 inches ).
10
The LAP receiver
It may be infrared or magnetic and it’s used to recognise a lap marker. In case of
Optic receiver an Infrared Transmitter, at the side of the track, is necessary; in
case of magnetic receiver the track must be provided of magnetic strips.
Infra Red receiver has to “see” the
transmitter placed on the trackside;
the gray point is the receiver eye.
Magnetic receiver has to be
installed on the floor of the kart, with
two tyre wraps. The arrows on the
magnetic receiver need to point to
the front and rear of the kart
MyChron 3 automatically recognises the lap receiver ( optic or
magnetic ) and so no beacon type configuration is needed.
11
The Optical beacon
The optical Beacon Transmitter has to be placed on the trackside to mark laps.
Ensure the infrared receiver eye faces the side of the track where the Beacon
has been placed, otherwise the system will not record lap time.
The Beacon transmitter is powered using 8 AA batteries or an external 12V power
cable. If you are using 8 AA batteries, unscrew the back cover of the Beacon
transmitter and place the battery pack into the transmitter casing.
The transmitter has two operating modes: Low power and High power. The Low
Power Mode has to be used when the track is less than 10 meters wide, while
the High Power mode has to be used when the track is wider than 10 meters.
12
To activate this function, please open the Beacon transmitter with a corkscrew
and place the clip ( located directly below where the battery pack is is attached
to the beacon transmitter board ) either over one of the two connectors ( for low
power mode ) or over the two connectors ( for high power mode ).
When the Beacon transmitter operates on high power mode, both the power led
lights will light up when the transmitter is turned on.
Please, take note that, in High Power Mode, the transmitter has to be
powered by an external 12 Volts battery.
13
How to install MyChron 3
Now you can start installing MyChron 3 on your kart.
It is recommended to follow these instructions in order to preserve your
instrument and to capture consistent and accurate data.
Installing and changing the display batteries
Two AAA alkaline batteries power MyChron 3. The batteries provide
approximately 40 hours of use. When the batteries require replacement ( < 2
Volt ), a battery indicator will appear in the top right hand corner of the display.
If battery voltage is very low ( < 1.7 Volt ) it will also appear the text:
LOW BATTERY
If battery voltage is really too low, the system will automatically shut down.
Replace both batteries when the battery indicator appears to avoid the system’s
shutting down during a test.
To change batteries, remove the two screws on the back of the display unit. To
remove the battery pack, hold each corner of the circuit board and pull the board
away from the display unit. When inserting the battery pack, ensure that the
batteries face the centre bolt and the circuit board faces the side of the unit. The
white connector should be positioned in the top right hand corner of the display
unit, if looking at the display unit from behind.
Do not over-tighten the screws when mounting the battery cover to the
back of the display unit.
14
Installing MyChron 3 on the steering wheel
Most of steering wheels have existing holes in the three central arms that will
accommodate the MyChron 3 display unit. If the steering wheel arms are solid,
mark the point where the hole is to be drilled and then indent a drill reference
point with a large nail or hole punch, to minimize drill wander. It is recommended
that an 8 to 10 mm drill bit be used. Do not over-tighten the 8 mm nut. Over-
tightening the nut may cause damage to the display unit casing.
As showed in the previous drawing, it is suggested to use the plastic
washers furnished as equipment to keep separate your MyChron 3 and the
steering wheel, in order to avoid possible damages to the display unit.
15
Installing the RPM clip
The RPM sensor clips directly on the spark plug wire.
While running the RPM cable along the chassis between the MyChron 3 display
unit and the spark plug wire, the RPM cable should be positioned as far as
possible from the thermocouple wire.
It is suggested to use cable ties to securely attach the RPM cable along the
chassis to prevent damage.
16
Installing the water thermocouple
The H
2
O thermocouple can be installed directly into the cylinder head ( if the
engine accommodates the thermocouple ) or by using the water thermocouple M5
fitting ( sold separately ) for the M5 type.
In the following drawing it is represented how to correctly install the water
thermocouple for the M5 type.
17
Installing the EGT thermocouple
The Exhaust Gas Thermocouple ( EGT ) should be positioned inside the exhaust
header pipe at a distance of 150 mm ( 5.9 inches ) from the exhaust port.
In the following drawing it is represented a correct installation of the EGT
thermocouple.
It is recommended that the probe be inserted between 25% and 50% inside the
exhaust gas header.
18
To install the EGT thermocouple, please follow these instructions:
1. Make a 5 mm ( 0.2 inches ) hole inside the exhaust header;
2. Weld the little nut to the exhaust header in the place where the hole has
been drilled;
3. Screw in the nut the central part of the EGT thermocouple;
4. Connect the remaining part of the thermocouple and fix it to the exhaust
header by screwing the big nut.
19
Installing the underspark thermocouple
When using a Cylinder Head Thermocouple ( CHT ) sensor, always remove the
spark plug washer before inserting the spark plug into the sensor.
When tightening and loosening the spark plug, minimise movement of the sensor
to avoid damage.
In the following drawing it is represented the correct installation of the underspark
thermocouple.
20
Connecting cables to MyChron 3
Once correctly installed all the parts of your MyChron 3, you need to connect
them to the main display unit.
On the back of the display unit you have to connect the temperature cable to the
upper binder and the lap cable to the lower one. The RPM cable must be placed
inside the two holes on the left of the display unit ( watching it from behind ).
21
While connecting the cables to the main display unit, it is strongly
recommended to keep separate the infrared or magnetic receiver, RPM and
thermocouple cables, in order to minimize interference between cables.

Utility functions
Once configured your system, you are ready to manage the data you have
acquired with your gauge. MyChron 3 records lap time, RPM and temperature at
a sampling rate of 10 Hertz ( ten times per second ). This data can be retrieved
at a later stage for analysis.
MyChron 3 segments data for a session as a test and each test includes the
laps completed in that session. To begin recording a new test, please turn off
your system off by pressing buttons MEM and VIEW simultaneously, and then
turn the system back on.
Viewing data
while driving
The MyChron 3 will display “Test 01” or the current test number
if memory has not been cleared, and “Lap 001” once the
magnetic sensor passes over a magnetic strip ( or the infrared
receiver passes the beacon transmitter ).
If the system has been configured to capture back segments
using the number of splits option, the system will display “Split
Number x”, up to the number of splits selected. Once the
system records times for each split, the final segment is
displayed as a completed lap.
At the same time the system displays the time difference
between the current split time and the split time of the previous
lap.
When the system records the best lap time for a test, the text
“Best Lap Time” will appear on the display.
31
When a test is complete, the system displays the last lap number and last lap
time. Using button MEM you will access the data stored in system’s memory.
