What numbers need to match up on ECU/MPEM for a replacement to work. For example my ECU has 2 numbers; 412252001/001 and barcode 6641300001. I see a lot of ECUs for sale that have the first number correct, but second doesn't match well, Or the first number after the slash is doesn't match mine for example a /021 and mine is a /001 (412252001/021) is that just a revision number?
