    What are you looking to do?
    Update the software of the ECU
    Or modify the existing software e.g tuning?

    A lot of tuners will mark a block on the flash unreadable so that you can't pull it over OBD.
    Then you'll need to bench the ECU to get it into boot mode to be able to read the whole of flash. Which means more expensive tools.
