Can't be done with OPCOM or Tech2 if the mileage on the clocks is more than 100 miles, i.e. brand new clocks.
The eeprom in the clocks has protected incremental counters and they can only ever be increased in value.
I can do it, but it involves replacing the EEPROM.
Mileage is also stored in the engine ECU which can not be changed without removal of the eeprom and re-writing.
As it says, disassemble the clocks, de-solder the 8 leg m35080 eeprom and read with a compatible reader.
Re-write the mileage section (Once you have figured out how the mileage is coded)
Write the modified file back to a brand new eeprom and re-solder onto the circuit board.
