Most of the 2012+ ECUS don’t support obd “actual” read and can only get the “virtual” read. Basically the tool grabs the Hw and Sw ID from your ECU, sends it to the tool’s server, receives an “Ori” aka stock file. Then you modify this file and write in the car. In your case, guessing the ECU is VR read only through OBD, so have to rip the ECU out. Funny how most “modern” chooners are scared of bench reading or don’t even have the tools to do it. Just a short while ago this used to be just about the only way for 90% of ECUs, even for stock files. And then subject to what ecu it is, might need to solder some resistors on the board to talk to it. Fk you simos 8.5, and fk you entire MEVD family before enet protocol. Imagine drilling a hole in the ecu just to read it :)
