hello friends. I have a Mk4 1.8T (150HP) 2002 upgraded reprogramming, K & N filter and full exhaust 2.5 "(210HP).
I would like to ask you today is no way to change the setting by entering OBD2.
I do not have much experience on the subject and would like your help.
As far as I know does not work in NefMoto M3.8.3 (06A906018CH).
Is there any software that can read and write in M3.8.3?

then there is no way to do this as they do in ME7?

But if I do it this way who told me:

Take the module out, feed the pin next to the OBD2 cable, what software would I use to change the program?

I need help, if someone can make me a tutorial or teach me step by step.

I apologize for the misunderstanding. What I meant was in steps.
For example the OBD2 connection simply plug wires junp pain car connector for the cable connector obd same?

I do not want anyone to make the schedule for me, so I'm afraid to do something wrong and end up damaging the center.

Here's your clarification... You can WRITE over obd 2 but you CAN NOT READ your original file from it with out removing the chip and use a chip burner
Hope that clears it up for you

Technically that is right. But I have found that some parts of serial eeprom & flash eeprom content are uploaded to RAM´s MCU (87C196). For example serial eeprom is located at RAM address $0C250 - $0C350. MCU Factory Test Code is located at address $02012-$02080H. Also data content of the flash eeprom (MAPs) seems to me that are uploaded too, but I am not totally sure about it.

As ME7 does and some code, procedures, maps & values are mounted in RAM for it process. The difference is that factory code in ME7 have procedures for it interaction, but in older Motronic are not available or at least are not public known. Maybe I am wrong, but that are my impressions playing with my ECUs.
