Pro Tip: MyChron4 Basics

Learn to prepare basic settings as well as what the external buttons and connections do on the MyChron4 Digital Guage and Data Logger.

We want to improve our data collection using the MyChron4. What are the basics in setting up this system?

In this installment of Pro Tips, with help from Andy Schlosser from Positive Motorsports, we’re going to show you how to set up your MyChron4 so that it’s more than a glorified stopwatch. With a proper setup, you can collect relevant and important data that you can then use in its proprietary software, Race Studio, made by AiM Sports.

Externally, the MyChron4 is a simple device. The front panel has four buttons that are clearly labeled, along with light indicators at the top. On the back is the compartment for the 9-volt battery, and starting from the top of the input connectors: temperature probe, lap monitor, and expansion port. There’s also an RPM loop on the bottom.

Back on the front side, turn your MyChron4 on by pushing the power button. To get into your configurations, press Menu once. Let’s find the wrench with the star; that’s your configuration wizard.

The questions you’ll be asked are straightforward, starting with what type of racing you’ll be doing. Most questions will be easy to answer, but we’ll help you with the important ones.

Setting your Maximum RPM too low or it could clip a bit and you may not get an accurate max RPM setting. Because the MyChron4 software works in increments of 2,000 RPM in this setting, we recommend going one setting above your expected RPM.

It would be confusing why you would put an inaccurate date in the settings, but in case you are thinking about it, don’t. The right year, month, day, and time will help in organizing your data when you’re importing into Race Studio.

Once you’re done with the configuration wizard, find your way back to the main menu and find the control panel icon which is a wrench. In here you can change the driver’s name and smaller system configuration settings which are covered in the video. Quickly run through those options to make sure everything is correct.

Back at the main menu, there is a track outline icon. This is to set up the circuit you’re racing at. Setting this up allows you to organize your data in Race Studio by the circuit and lets you build maps easily.

Back in the main menu again, look for the icon with the mini AiM beacon above a checkered line. This allows you to set up your minimum lap time so that you don’t get bad data, like pace laps, imported into Race Studio. Set this 2 or 3 seconds below your typical time. For example, if you’re at a track with a 55-second lap time, set your minimum lap time to 52 or 53 seconds.

If you happen to be lucky enough to have multiple engines, there’s a configuration in the main menu to select which engine you have on the kart so that it keeps track of the time on that specific engine. This way if the hours start to mount-up on an engine since it was last refreshed, now you know exactly how much time it has on it.
