Page 5: Getting Started With M Y Chron 3
Getting Started with MyChron 3 Aim has developed and tested your MyChron 3 to provide precise and accurate results. Here are the parts of your system: • MyChron 3 Display Unit ( 1 ). • RPM sensor ( 2 ).

Page 7: Mychron 3 And Its Parts
Before installing MyChron 3, please read carefully these installation instructions. It is very important that your MyChron 3 is correctly installed to capture consistent and accurate data. Incorrect installation may result in system malfunction. In the following drawing it is represented MyChron 3 mounted on a kart steering wheel.

The Keyboard >> VIEW MENU on quit << The Keyboard, composed by four push-buttons, is used for turning the power ON and OFF, configuring the system, recalling the recorded data and clearing the internal memory. The four pushbuttons are used for: MENU/<<...
Page 10: 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...
Page 11: The Thermocouple
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 O - Water thermocouple1/8 inches type. 2. H O - Water thermocouple M5 type 3.
Page 12: The Lap Receiver
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.
Page 13: The Optical Beacon
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.
Page 14 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 ).
Page 15: How To Install M Y Chron 3
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.
Page 16: 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.
Page 17: Installing The Rpm Clip
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.
Page 18: Installing The Water Thermocouple
Installing the water thermocouple The H 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.
Page 19: Installing The Egt Thermocouple
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.
Page 20 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.
Page 21: Installing The Underspark Thermocouple
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.
Page 22: Connecting Cables To Mychron 3
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.
Page 23 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.
