Discussion contrasting.. but ets ecu you can do in the serial or not?
The file is partial or total engine management?
If you have the bench equipment to the edc16, according to me, it is always better to read them in a bdm for a bk...then in serial to proofread and games as long as you want.
I in my astra h , the first time read in bdm , and then written in serial with cock v54
write writes the sound management (always if from the file bdm-healthy to write ) then the changes are effective
