About this file

Typical uses: restoring a control unit to its factory software after a failed flash or a corrupt memory, a clean base before any change, comparing a read of your own with the original. The checksum is the one of the read; your programmer or the CARTESIAN app corrects it after a change.

  1. Order with your e-mail address; the download link comes right after the payment and is valid for 30 days.
  2. Open the file in your programmer, compare its numbers with your unit and check the checksum.
