MyChron 6 Setup Guide

AiM MyChron 6 Setup Guide

This guide walks you through installing and setting up your AiM MyChron 6 on a kart, including mounting, RPM, temperature, built-in GNSS and first-time configuration. Written by Rex Harris — professional qualified radio engineer (RSM Approved Radio Engineer ARE127 and Approved Radio Certifier ARC127) with decades of motorsport electronics experience — and Charlie Harris — national-winning kart racer, Canterbury University engineering student, and kart race engineer — at Harris Race Radios, the Official AiM dealer in New Zealand, supplying genuine AiM Sport products. For kart racers in New Zealand.

What you need

  • AiM MyChron 6 1T or 2T dash and the correct mounting hardware.
  • The correct RPM pickup lead and an engine-specific installation procedure.
  • The compatible temperature sensor and any required patch lead, extension and mounting adaptor for the selected engine and dash.
  • Suitable cable securing materials and the tools specified for the actual fittings.
  • The MyChron6 manual and exact engine/sensor instructions. An external GPS08 is not a standard requirement: MyChron6 has built-in 25 Hz GNSS.

1. Mounting the MyChron 6

  1. Use the specified mounting hardware and fixing procedure for the steering wheel and dash.
  2. Position the display so it can be read without obstructing the driver's view or controls. MyChron6 has a graphical display with 16 grey levels and configurable RGB backlight, not a colour TFT display.
  3. Check that the mounting is secure and steering can move lock-to-lock without fouling the dash, wiring or bodywork.

2. Installing the RPM pickup

  1. Follow AiM's pickup installation procedure for the exact engine and ignition arrangement. Do not apply a universal minimum of 5–7 wraps.
  2. Secure and route the pickup as documented, clear of exhaust heat, moving parts, abrasion and unintended ignition interference.
  3. Use the connection shown in the MyChron6 wiring diagram; do not force a connector or assume another generation's port arrangement.
  4. Set the correct RPM factor for the ignition pulses and crankshaft revolutions. AiM specifies RPM acquisition at 20 Hz or 50 Hz, not a blanket 200–1000 Hz MyChron rate.

If RPM is unstable or missing, verify the pickup arrangement, connection and factor before changing the lead position or adding wraps. Stop and ask Harris Race Radios if a reliable signal cannot be established.

3. Installing a temperature sensor

Choose the measurement required by the engine: water temperature on a water-cooled system, CHT at its specified fitting, or an appropriate EGT probe. Match the exact sensor, connector and patch lead to the 1T or 2T arrangement; do not assume a generic “CHT/WT” socket applies to every configuration.

  1. Follow the engine and exact sensor's mounting instructions, including hose/adaptor dimensions, thread/seal or probe placement as applicable.
  2. Work on a cool engine and follow the correct coolant draining/filling procedure where required.
  3. Route and secure the sensor lead away from exhaust heat, abrasion, moving parts and interference.
  4. Configure the correct channel function and units and check a plausible reading. AiM provides automatic and manual temperature-function selection; confirm the resulting label matches the installed sensor.

Use the water-temperature installation guide or MyChron sensor installation guide for the relevant procedure.

Engine-specific temperature settings

Set normal operating targets, warning alarms and stop limits from the exact engine manufacturer's or engine builder's requirements and applicable class rules. No universal Rotax, Vortex or Briggs coolant-temperature table applies. A sensor measurement range is not a safe engine range, and an air-cooled engine does not have a coolant-temperature target.

4. Built-in GNSS and track setup

MyChron6's internal 25 Hz GNSS receiver provides lap timing and track data. Do not install or purchase an external GPS08 as a routine requirement for this dash. Position the dash according to AiM's mounting guidance and avoid obstructing satellite reception.

Allow reception to establish outdoors and check satellite/track information using the model's documented status display; no universal lock time or indicator-colour rule is prescribed here. Verify the correct circuit layout, start/finish and split information before relying on lap comparisons. Harris Race Radios can help with incorrect or missing NZ/AU track maps.

5. First-time configuration

  1. Confirm the exact 1T/2T model and installed sensors and optional expansions.
  2. Use the MyChron6 system settings to verify RPM factor and 20 Hz or 50 Hz RPM acquisition.
  3. Check temperature function, units and engine-specific alarm thresholds.
  4. Configure optional speed or expansion channels only when the corresponding supported hardware and wiring are installed.
  5. Verify track selection and GNSS reception before the controlled test.

Optional ACC3 channels require the appropriate sensor, harness, master configuration and firmware. The ACC3 up-to-1 kHz input specification is not a general MyChron6 or RPM-channel logging rate.

6. Testing your installation

  • Check steering clearance and secure mounting before starting.
  • Confirm a stable, plausible RPM signal and correctly identified temperature channel.
  • Warm the engine only according to its maker's instructions and monitor the verified limits.
  • Check for leaks, interference or unusual readings and stop if anything is abnormal.
  • After a safe controlled run, confirm session and lap data are recorded and compare values against known references.

7. Troubleshooting common issues

  • No RPM reading: check pickup installation, connection and RPM factor; do not automatically add wraps.
  • Missing temperature: check the exact sensor, connector/patch lead, channel function and units before replacing parts.
  • No GNSS reception: check the dash's reception conditions and documented status, not the position of a presumed external GPS08.
  • Persistent faults or engine distress: stop and contact Harris Race Radios or the engine builder as appropriate.

8. Downloading and analysing data

  1. Use the supported Wi-Fi or USB connection with the appropriate cable and current compatible Race Studio 3 installation.
  2. Download and save the session before making configuration changes.
  3. Review lap times, RPM, speed and track information with attention to data quality and conditions.
