Hello!
For SWI68, the latest version that includes MPU + MCU on USB is R59. Updating only the MPU to R71 will definitely break the ability to set charging limit via FICM(only using app will be posibible). Jumping to a such higher version while MCU is so much older can break other things.
R59...
@BingBong I don't think is a good idea to swap MCU between SWI68 and SWI69. SWI69 has MCU 69.x.x.x and SWI68 has MCU 68.x.x.x.
When I had R67 with older MCU(68.4.3.0) I could not set the charge limit in the FICM
I think higher MCU versions are compatible with lower MPU. I updated to 68.5.2.0 while I was on R67. Yesterday I updated to R71 and today there was no update for FICM in SIPS. The 68.5.2.0 is available in SIPS since 2026-01-23
I had to update my TBOX (MPU + MCU) because Keyless Start from app was not working(had SNAKP18E32 and updated to 23E32)
As a recap:
FICM for SWI69 is done entirely from USB(MPU and MCU)
FICM for SWI68, starting with R63 is two part: MPU via USB and MCU via SIPS
TBOX for both SWI68 and SWI69 is...
