    Hello all.

    Now I'm trying to read/edit/reflash an F430 ECU.

    With the Galletto 1260 I can read and write ROM file, but something's wrong.
    On the left is the genuine ROM file, but when I reflashed it I found that many addresses have a lot of unintended offsets. (FA->EA etc.)
    Any useful advice or possible causes?

    Thanks in advance.

    Thanks for your reply.
    I didn't fix the checksum but I had the same problem when I read the original ROM from an unmodified ECU.
    The address 0x00001 should be FA and the ROM file I read from the original ECU starts with EA.
    (For previous post I'm mistaken,the right side is genuine)
    I tried to read it with KESS V2 but had the same problem.
