Mine is set to -6% and now seems to be pretty accurate. That does mean 23mpg though

So the published mpg figures are impossible to achieve in the real world, and the trip computer is 'adjusted' at build to be at least 7% optimistic. Fortunately Land Rover don't build passenger aircraft! Previously:

Well I have wound mine back from +7% to -7% already, so that is at least a 14% change. Land Rover - Turning Drivers into Mechanics Since 1948
