How to Read MyChron Data
How to Read AiM MyChron Data
This guide teaches you how to analyse data from your AiM MyChron 5 or MyChron 6 using AiM RaceStudio 3. It covers lap times, RPM, speed, GPS racing line, temperatures, and driver comparison — essential for kart racers in New Zealand and Australia.
Why MyChron data matters
Analysing your data helps you:
- Find where you are gaining or losing time
- Improve braking, cornering, and throttle control
- Set correct gearing and jetting
- Compare drivers or sessions
- Understand engine performance and reliability
1. Lap time analysis
Lap times are the simplest and most important part of data analysis. Look for:
- Best lap — your fastest lap of the session
- Consistency — how close your laps are to each other
- Drop-off — tyres overheating or driver fatigue
- Traffic laps — ignore these when analysing performance
- Cold tyre laps — expect slower times early in the run
2. Sector and split analysis
Splits show exactly where time is gained or lost. This is more valuable than lap time alone.
- Identify your strongest and weakest corners
- Compare sectors between sessions or drivers
- Focus practice on the slowest sector
3. RPM analysis
RPM data helps you understand engine behaviour and gearing. Look for:
- Peak RPM — should match your engine's safe limit
- Over-revving — too small a gear ratio
- Bogging — too tall a gear ratio
- RPM drop on corner entry — indicates braking technique
- RPM rise on exit — shows acceleration efficiency
4. Speed trace analysis
The speed trace is one of the most powerful tools in RaceStudio. It shows:
- Braking points — where you lift or brake
- Minimum corner speed — key for lap time
- Acceleration zones — how quickly you get back to speed
- Exit speed — critical for long straights
5. GPS racing line analysis
The GPS map shows your exact line around the track. Compare your line to a faster driver or your own best lap to identify where you can improve entry angle, apex position, and exit line.
6. Temperature data
Water temperature, CHT, and EGT data help you understand engine health and jetting. High temperatures may indicate cooling issues or lean jetting. Low temperatures may indicate rich jetting or a thermostat issue.
7. Driver comparison
Overlay two laps in RaceStudio 3 to compare speed traces, RPM, and GPS lines. The delta time graph shows exactly where time is gained or lost between the two laps. See our Driver Comparison Guide for full detail.
