Make sure to run the loader as Administrator to avoid any issues with file permissions when saving your work, especially if you have the software installed on the C: drive.
As a final precaution, ensure that you block the executable in your firewall. This software is known to attempt auto-updates when online, which can deactivate the раtсh if it connects to the server.
Just a quick tip: If you use it for AdBlue removal, make sure to disconnect the AdBlue control unit (DCU) connector on the vehicle before writing the modified file, especially on PSA and Renault systems. Otherwise, the dash lights might not clear even with the correct file.
One last piece of advice: Always keep a full backup (Flash + EEPROM) of the original ECU data before applying any Davinci patches.
If the software calculates a checksum incorrectly and bricks the ECU, you will need the original backup to restore it via Boot or Bench mode using your programmer (KTAG, KESS3, etc.). It is better to be safe than sorry.
