Flex read/write Marelli MJD 8F3.Compare virtual reading and original reading.Lesson for beginners !

As I said in the video, those who sent me these ECUs, did not know which belonged to the car. That service deals with repairs only for Ducato, Boxer and Jumper and when you disassemble a car for repairs, and the repair takes a long time, unfortunately such things can happen. Since I had the opportunity to compare an original reading with a virtual one, I did this for those who are starting in this profession. It is very simple why the reading is different, but this is what I hope to see written by those who are interested in tuning. I hope this information is useful to you!
