The latest version of the AiM Mychron 5S has landed. Our game-changing datalogger has been specifically designed for Kart racing whether you're on a scaled-down circuit or a professional full-sized motorsport circuit for thrill-seekers and competitive races this is the datalogger for you.

The GPS frequency has improved from 10 to 25Hz and the precision and accuracy have been improved from about 5 feet to 2.

With integrated GPS this system takes advantage of our global track database, to automatically understand which track you're at. When you get to the track switch on your MyChron 5S and it will determine its position, identify the track and start loading start/finish line coordinates. Even the predictive time is much more reliable thanks to the improved GPS you will know the exact time gap vs, your best lap.

The MyChron 5S Kart lap timer features a high-resolution graphical display with built-in 25Hz GPS to sample and record lap times. The MyChron 5S combined with a choice of water temperature sensor and RPM connection makes it the ultimate karting lap timer.

The MyChron 5S logs and stores speed, lap times (including split and predictive), gear, temperature, RPM as well as data from the optional sensors when connected to the MyChron Expansion Box, such as throttle position sensors, brake position and pressure sensors, steering angle sensors and the LCU-One Lambda Controller and SmaryCam which are available in our accessories tab.
