- Support for ecu serial #10267
- A customer's V3.6 ecu suddendly lost serial number, seems to be in a kind of limp mode (10° and 0.65 lambda at any load/rpm).
- VemsTune is now displaying that Serial is unknown-0.

If considering bootloader upgrade, (so that internal BOD can be disabled) highly recommended:
PLEASE CHECK THAT v3/10267 has reset chip at the atmega128/pin20 reset, eg
- mcp121 or mcp131 (U26 position)
- or mcp809 or max809 (U10 position)'''
