MyChron 5Queensland Raceway National
A MyChron 5 session open in Purple Sector: the Queensland Raceway National map with its six turns and the gap at each, beside the list of laps.
Shown: a real MyChron 5 session at Queensland Raceway National. A file from any logger Purple Sector reads opens in the same view.

RaceBox exports happen on the RaceBox website, not in the phone app. Once the app has uploaded a session, sign in at racebox.pro, open the session under My Sessions and export it as VBO, CSV or GPX.

Because the export is on the website, a Windows PC or a Mac works. RaceBox also lists its app for Macs with Apple silicon. A Mini S or Micro records on its own, and Chrome or Edge can read its sessions straight off the device over Bluetooth.

The original RaceBox Mini needs a constant connection to the phone to record, so there's nothing on the device itself to download; export its sessions from the website.

How do I get the session file from a RaceBox?

Bring: a .vbo exported from racebox.pro

On a computer

  1. Open the RaceBox app with your phone online, so the session uploads.
  2. Sign in at racebox.pro, open “My Sessions” and open the session.
  3. Press the export button on the right and choose VBO.
  4. Open that file here.

On a phone

  1. Open the RaceBox app online, so the session uploads. The app itself has no file export.
  2. In this phone’s browser, sign in at racebox.pro and open “My Sessions”.
  3. Open the session, press the export button and choose VBO. It saves to Downloads.
  4. Back here, open your lap file and pick it from “Recents” (iPhone) or Downloads (Android).

Watch out: Choose VBO, not GPX. A GPX has no G-force data.

What else should I know about the file?

Limits to know
  • Sessions with no laps are hidden in My Sessions: use the link at the bottom of the list to show them.
  • A Mini S or Micro records on its own, and Chrome or Edge can read its sessions straight from it: Download from RaceBox (Bluetooth).
  • Safari, iPhone and iPad browsers and Firefox cannot use Bluetooth from a web page, so export the session from racebox.pro there.
  • The original Mini streams live to the app and keeps nothing to download.
GPS rate

The exports we have checked were recorded at 10 Hz; the hardware can also record at 25 Hz. Either is fast enough for AI coaching. What GPS can and cannot show.

Can I download a session straight from a RaceBox Mini S or Micro?

In Chrome or Edge, yes: choose Download from RaceBox (Bluetooth). Safari, iPhone and iPad browsers and Firefox cannot use Bluetooth from a web page, so use the RaceBox app’s export there.

Is there a RaceBox app for Windows?

RaceBox lists its app for iOS, Android and Macs with Apple silicon. On a Windows PC, export the session from racebox.pro in a browser and open the VBO or CSV here.

Does the original RaceBox Mini work?

It streams live to the app and keeps nothing to download, so there is no session to open from it.

What do I see once the file opens?

Lap 6 picked against lap 1: the gap to lap 1 at every turn on the map, T3 the largest at +0.87 s.
The gap to your best at every turn.
The map closed on T3, marked +0.87 s, with both laps' lines through the corner.
The corner that cost time, with both lines.
The AI Coach card for T3, +0.87 s: “Turn in about 2 m wider into T3 and get back on the throttle about 3 m sooner out of it.”
One card for that corner, with its numbers.
