Click the OpenBinaryFile button on the left to select the binary file to make modifications to. The following dialog pops up :

Select the file you need and click Open. The program returns to the main window and the event log starts to update to give you informations about the opened binary.

The program starts to search the binary to provide the following informations: the status of the DPF system ( on / off ), the adress of the DPF Switch, the number of DTCs ( error codes ) found in the binary and their start adress, the location of the EGR strategy maps. Unlike most DPF/DTC tools, this program does not rely on a certain software version of the binary to fetch the correct adresses. The smart search algorithm can detect the structures so that the program always makes the correct change at the correct adress.
After the program has finished searching for structures you may start making changes to the file.
