Everything you can set in AB Racing Line is in one panel: the units every number is shown in, the size of the app, help when something looks wrong, and your account.

Pick Metric or Imperial, or mix your own
Metric and Imperial set everything at once. To mix, pick each kind on its own, say mph with °C and psi: the set becomes Custom.
Press Save
Every number in the app follows straight away: every tab, your engineer's coaching, the setup changes and the overlays. Your choice is kept for next time.
SizeUI scale: the size of the app
- 1The sliderFrom 80% to 130%. The preview under it shows the new size as you drag.
- 2Apply and RestartThe app restarts at the new size.
It scales text and boxes together, so everything stays in proportion. Bigger helps when the app is on a screen you read from your seat.
HelpQuick fixes and release notes
Quick fixes lists the few things that look broken but take ten seconds to fix, like an overlay that went missing or an OBS source that went blank. The same list is in Questions and quick fixes.
Release notes shows what changed in the version you're running. It also opens by itself once, the first time you start a new version.
