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.

In CARTESIAN this original file is the base for the solutions it supports, such as DPF off, EGR off, lambda off and DTC off, each saved with a correct checksum, and for returning a modified unit to stock.
