120EF - Incorrect Datalog File

    November 19th, 2021

    • Make sure to correctly select the datalog file that matches your vehicle type.
    • Make sure the device is not in demo mode: From the main menu go to (Device Settings). Scroll to the bottom and you will see demo mode, make sure it says disabled, or off.  
    • If those things do not correct the issue, you can try performing a "Factory Reset".  To do this go to the main menu, then select "Device Settings" and select "Factory Reset". Note: if you perform a factory reset it will delete any custom tunes that are loaded to the device.
