I am not fun of immo off, one case was work for one ignition cycle, and second cycle we get ECU immobilised, probably the person who did immo off forgot to lock eeprom overwriting protection, but for the newest cars is pain to adapt used ECUs.....
I was search manually the pin code, locations are 0x0A0-0x0A1 and 0x0AC-0x0AD and those values calculate from Hex To Dec , values are repeated twice. You have nice software.. I was searching some free but didn't get anything.. but have manual method:) I think You already know that adaptation on those ECUs is simple by vcds just pin from the car and new(used ) ECU . There is no way to obtain this pin by obd. Only your method will extract the pin . Any chance to get this software somewhere?😅
Also struggling to find ignitions or injectors drivers on this ECU? I think is large IC but not reverse engineering done yet😂 should be some sort of mosfets behind...
