This article begins with one user's feedback: how can I solve the OTP problem? I try to clone an ECU. I read the file fine but I can't write. I get the error at 3%. And followed with one image shown as below.


First full read of ori and donor ecu
Second. Use Tricore clone function. That will give you file to write.
Third. Use normal write option but you need to write file that was made by program. And write ori non mod eeprom file to new ecu.
