....
I just realised I should add that my long term 28 mpg is as displayed on "2" which I think is overall rather than trip - Is that correct? What's "1", on the fly as you drive?
Both are 'on the fly'.
Number 1 - This shows all data for your
current journey. It is reset only when the engine has been off for at least 2 hours.
Number 2 - This shows the total for as long as you dont reset it! These figures only rest when you reset it yourself, or when the time travelled reaches somet silly - I think its 999.99 hours.
So lets say you reset both sets of averages, before a 2 day break, for example.....
Day 1 - you travel 200 miles.
Day 2 - you travel 300 miles.
Number 1 data - will show you all the averages at the end of each day/journey. It will reset 2 hours after your journey on day 1, and 2 hours after the journey on day 2, and so on. So when you get in the car on day 2, all averages under this setting will be at 0.
Number 2 data - will show you averages for the complete 500 mile journey. Hence at the beginning of day 2, all data from day 1 is still there, and the computer adds day 2 data to it.
Both sets of averages are always changing in each journey - the only difference being the reset times.....
