Question:
Has anyone successfully cloned a Peugeot Valeo VD56.1 ECU using the Xhorse Multi-Prog? I can read and write both the flash and EEPROM without any errors, and the writing process completes successfully. However, after installing the cloned ECU, the engine won’t start. Has anyone experienced the same issue or found a solution?
Here is the clue.
VVDI Multi-Prog reads the VD56 ECU in Boot Mode successfully, but it cannot perform a full 1:1 clone because the MCU contains OTP memory.
Multi-Prog does not support checksum correction for the VD56.
Multi Prog can read the MCU ID, which is required for IMMO OFF operations.
This MCU includes OTP regions and a unique MCU ID, so rewriting the MCU data will cause the MCU to lock.
