    Hello, I want to understand if I need a bypass cable for my car and if I need to "open" my file.
    If so, I would like to know which cable I need.
    Because I have seen the use of all kinds of cables. thanks.

    You need a bypass cable to download your calibration from your ecm, I use GDP bypass cable. You need at least the MPVI2 to download and open your calibration file
