Ok so I'll try to explain as best as possible..
On the MFD with the MPG and average speed settings etc there are 2 sets of recordings which you can change through by pressing the 'ok' button under the wiper stalk.
number 2 is a long term record of what the car has done in terms of average MPG and is only reset by holding the 'ok/reset' button.
number 1 seems to reset each time i start the car for a new journey.
What I want is for it never to auto reset so I can reset it manually (like number 2) so then I can use number 1 to display what that tank of fuel has done and then rest each time i fill up.
Hope that made sense...
Is it possible?
Thanks
Nathan
