I can't change anymore the reference consumption @110km/h. If I try it it goes up for me Mustang Mach e to 1850 instead of what I typed 220
I use Android device Samsung galaxy S22+ Android 13 latest September Patch it's an Europa Modelle. App Version is 4.6.0 2401
Select another car in the list and then select your Mustang Mach e. That should solve the problem.
