    Read Fail - MPVI 2

    Hi Guys,

    So I've just bought a 2018 mustang GT and today I tried to download the stock tune out of the ECU using my MPVI-2.

    Since I haven't updated the unit in a while I got online and resync'd the interface with the latest firmware and updated to the latest Editor version 4.4.4

    Once I connected to the car, hit the Get Info button first and it recognized the ECU and car VIN number. Once I hit the read button all of a sudden the car dash starts flashing and beeping, turns on and off by itself and the Editor is saying "READ FAIL".

    IS there a trick to reading these new Mustangs or am I doing something wrong. Any help please.!!

    Cheers Allen
