Title: ECU flash and vin overwrite Post by: MongeIvan on May 31, 2022, 09:46:07 AM Hello,
Sorry this my be a very noob question but when you do a full ECU flash with nefmoto software does it overwrite the VIN? I want to replace the ecu to an engine.

The ME7_EEPROM tool can be used to read, make changes and (boot mode) write the EEPROM memory. http://nefariousmotorsports.com/forum/index.php?board=42.0 If the EEPROM command line program is difficult for you to use, there is also a GUI for it bundled in the ME7 visual logger that is a bit more user friendly. |
