[Notice] ECU Upgrade Server Migration

Hello.
To provide a more stable service, we will perform an ECU Upgrade
server migration.

• Maintenance Schedule: January 24, 2026 (Saturday), 09:00–18:00 (KST)

• Service Impact: During the maintenance period, access to certain features (OTA-managed version upgrades, individual event downloads when resources are missing, and ETCS upgrades) will be temporarily limited.
   ※ However, the existing ECU Upgrade (=Auto Mode) feature will remain available as usual.

We apologize for any inconvenience. 
We will make every effort to ensure stable service.
All services will be available as usual once the maintenance is complete.
