120EF Incorrect Datalog File

Modified on Fri, 2 Sep, 2022 at 12:05 PM

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.
