Yessir, it really is the easiest. It's the 95640 chip (8 pin) that sits on the other side of pcb. You have to remove the 4 screws that holds pcb and then flip it over to get to eeprom.
Once you cloned the eeprom, then you can flash the ecu with the correct software version. Once this is done, you code ecu. Only then do you try and read ISN from ecu. I've now done many many of these MSV80 ECUs with no worry about power class anymore.
The eeprom you read using ISN Tool is virtual eeprom in Tricore, not physical eeprom on pcb.
hello friend good afternoon I have an ecumsv80 was 3.0 cylindrics now I have 2.5 because I got an ecu by ebay of them but I get 2.5 and can leave half, edio of the mess because I turned on but the issue is that the car was with little power I need to pass it to 3.0
I have an ecu that according to the part number is 3.0 but it is bad and I uncover it and it has eprom 95640 and so I understood if one passes that eprom can one update it to 3.0 the question of mine is if the autohex passes it to me to 3.0 because I put eprom of 3.0 that's what I'm going
I have a problem with the client because I do not get another one at the moment and I have that doubt to pass the eprom and see if it goes to 3.0 since I programmed the same in individual coding and he updated me the same ecu but not the change of displacement maybe why is 2.5
if I pass the eprom that has the ecu 3.0 it will be passed to 3.0 again friend thanks
I also have a wasapt autohex group. If you like to add it, I add it, my number is +573133048798 If you like, keep the number like that and write to me, I appreciate your collaboration too
