We already exchanged PMs
The mileage is stored in a separate IC on the board (93c46 for those familiar). De-soldering is not that easy due to the nearby plastic frame. The data content is allways the same for all bikes, except the mileage. No protection or coding to a specific ECU or key. Yamaha also provided the programming pads (for production purpose) on the bottom. Quite easy to read/write with a proper (simple) programmer.
