Yes, but first you will have to download the track to Race Studio 3.
First connect your Mychron to the program ( in the upper right there is a wifi logo, there you should find your it, if not its wifi must be turned off; go to the wifi options in your Mychron and turn it on) If you have set a password, the program will ask for it (if you haven’t, you definitely should!)
Once connected, click on the track thumbnail in Race Studio 3, should be near the top. Now select your Mychron (should be on the lower left of the program) all the tracks stored in it will apper on the right list, including the track you wish to edit its name.
Before doing this you first have to download this track. Select it by clicling on his check box, then click download (or something similar, sorry don’t remember the name now, I’m typing on my phone) now this track should appear on the left list, ready for editing. Click on the gear thumbnail nail on the right of the track name select “open for editing”. Now you can edit its name, beacon position and some more options, before leaving this windos click on “save”.
Finally, you have to transmit the edited track to your mychron, to do so select it from the left track list and click “transmit”.
Hope it helps!
