[Notice] ECU Upgrade Server Migration

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

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

• Service Impact: During the maintenance period, access to certain (OTA management version upgrades, individual event downloads when resources are missing, and ETCS upgrades) functions will be temporarily restricted.
   ※ However, the existing ECU Upgrade (=Auto Mode) function will remain available.

We apologize for any inconvenience this may cause and 
will make every effort to provide a stable service.
All services will be available normally once the maintenance is complete.
