MyChron4 is the revolution of data acquisition in the kart racing world; it means a new way of showing the most important information acquired in test sessions, during the race and in analysis : RPM, Temperatures and Lap time. We’ve stepped up our technology with a pixel-based graphical display that easily shows large, easy to read numerals (like exhaust temps) as well as sharp, detailed, histograms and graphs (like torque curves) and even images (like team logos). Get more from your MyChron4 without the need of a laptop connection; you can in fact view lap/split times, power curves, RPM histograms, temperatures, best theoretical and best rolling lap, right on the display. Replay your entire racing session as soon as you get off the track!

There’s more in MyChron4 than just a pretty case. Check out these advanced features: - Two configurable Alarm leds - Configurable shift leds - Intuitive menu design for easy configuration - Automatic start - Long life battery (up to 200 hours with an internal 9V battery) - 1 MB memory

Digital graphic display with amber or green backlight.

RPM and Temperature alarm leds.

MyChron4 DataKey for fast data download and firmware update.

MyChron4 eBox for further performance improvement .

Your data - RPM, lap times and temperatures - at your command.   Using sensors installed on your kart MyChron4 measures water temperature as well as the temperature of exhaust or cylinder head and helps you keeping your engine at its top. Fast and easy check of your data through instant playback let you get the most from your time on the track. You can of course see your lap times as a whole or as partial laps (segments / splits).  As always, AIM stepped things up a notch providing Forecast Lap Time – a first in kart gauges.

Forecast lap time

Powerful, flexible graphical display for extreme visibility and easy customization.   The advanced pixel-based graphic display fits each situation showing large numbers during the session (when you can only spare a quick glance at the display) and easily switching to smaller text during analysis and review. In data review you can select various styles of graphs and histograms, easily visualizing your data right away. Get the information you need to make sensible adjustments to your kart, engine, and driving strategy. Personalize your MyChron4 and your data filling your name in and uploading your team logo; dates and times will have your name!

Session summary

The new, simple and intuitive way to quickly analyze the information you need.   Years of experience in data acquisition led us to develop quick and simplified analysis functions:

Max/Min RPM per lap (US version)

Variation: gap between current lap and previous one

Water Temp Graph

Three leds to keep temperatures and RPM under control   Easily set min/max alarm leds to monitor temperatures (side leds) or RPM (central one) and keep your engine at its top performance. These bright, easily configurable leds blink as a warning when fixed threshold value is being passed.

Advanced power management technology for endurance on the track   An internal 9V battery provides enough power for most karts; for additional functions/optional (GPS, Lambda probe), an external battery connection is recommended.

eBOX Gold and eBox Extreme   MyChron4 eBox are external expansion modules that let you further expand the already great potentialities of your MyChron4.
