Not a very clear picture but I think mileage is in the mcu

[nujtech]

hi thank you foe the reply , so did you mean i cannot adjust the kilometer reading?

[al70]

Yes , possible but I don't think mileage is in eeprom, I think it's in MCU

[al70]

Have you removed the needles, Speedo and RPM pointers ?

[nujtech]

no because the pcb front side is only a back lights.10e60e84-cc89-4fe6-b98a-463a94b4f725.JPG

It's a msop8 micro eeprom, some are labeled a86 but can be read as c86, hope this helps
