AC EVO servers are configured with two JSON files from Kunos:
- serverconfig - the server itself: name, slots, passwords, network settings.
- seasondefinition - the event: track, cars, sessions and race rules.
The Config tab lets you edit both. A guided editor is on the way; until then, it’s the raw JSON.
Safe editing
- The editor checks your JSON as you type. If it says it’s invalid, the server never sees it.
- Format tidies indentation so it’s easier to read.
- Save sends the files to your server. If it’s running you choose: Apply now (it restarts, and the panel asks first) or On next restart (nothing happens until you or a schedule restarts it).
- History keeps your last 50 saves. Pick one to see exactly what changed, and Restore it if a change didn’t work out.
- Server name and passwords live under Settings, not here - the panel fills those in for you.
Tips
- After a game update, Kunos sometimes adds new options (0.9 added pit-stop rules). Our changelog notes anything that affects config.
- If the server crashes right after saving, the console usually says which setting it didn’t like. Fix it and save again.
