bmw e87 118d edc17c06 dpf egr off

[r3aperx]

Hello friends,
I am trying to do dpf off on bmw e87 118d edc17c06 .
I used DPF-EGR-Lambda-Remover-05.2017 on this ecu edc17c06 and kess v2 , after this the car won't start , write back the original file and the car starts ok .
I belive this program does something wrong to the file , i also put the file in winols and it does find 1 checksum error , fixed it with winols but the cars still does not start.
Can someone please help me in this matter (attached the backup file) .

This SW number has Tuning protection,you cant write it with kess,only read it,this is your problem.You need to open ecu and read it with ktag,or some other tools

[karmoranas]

yes, read ecu on table

Kess V2 from China does not do a correct write of this ECU.

Ok, thank you for the info .
So the file created by DPF-EGR-Lambda-Remover-05.2017 should be fine but is not beeing write corectly to the ECU , strange thing is that when i write back on ecu the original backup file the car starts and works fine, but not with the modified one .
I did found protocol 226 write the file on bench with kess V2 (clone) by conecting 1 pin on the board and the rest to ECU pins, would that be fine ?
