Re-map fuel economy

Sorry if this has been covered before. I know some people have said what the display reads, but has anyone done any tank to tank calculations. While I am anal about fuel economy i drive on some winding and undulating roads so the overtaking has to be done quickly so i am interested in a bit more overtaking power, while maintaining my current fuel economy. I was thinking based on what has been said on here about the Celtic turning remap. My car is due due for it first service this week so I may go for it afterwards.

Thanks for your info.

Keep looking at them myself

But I have a company car

I did do some calculations very early on when I got the vehicle. I found that computer was less than 0.5mpg out.
I'm now run in properly (having just had my first service), so I think I will start a spreadsheet - I forget who, but someone on here has one already...

Work with actual litres put in and used...

Also, when browsing the net, a there is a big difference in what is quoted as litres to the gallon. I work with 4.454 litres to the gallon.

Does anyone have an absolute reliably accurate figure?

1 pint is 568.26125ml which is 0.56826125L

1 Gallon is 8 pints

Therefore 1 Gallon is (0.56826125*8 ) 4.54609 Litres

These figures are from the Government Units of Measure Regulations 1995

Of course fuel volume varies with temperature, hence aircraft using weight.

I have been told that the best (cheapest) thing to do is fill up early in the morning and don't go to the brim as when the fuel warms up in the tank and expands some will be lost out of the breather. Bit anal though!

Hello chaps, for your info, I have a remapped 2.2 and got 500 miles from a full tank of BP Ultimate Diesel last week. Car was driven carefully, and braking was kept to a minimum (allowed car to slow under it's own weight heading towards roundabouts, etc.).

Equally, if I drive it hard, I'll get 350-390 miles to a full tank.

Go for a remap, they're well worth the money. Every diesel car I've had (on my third) has been remapped and tweaked in some way.

I've kept a spreadsheet of MPG since I got the car, I've now done over 20k in it.
The car MPG typically avarages 2.3 MPG higher than the actual figure I compute.
Car MPG is trip A before I fill up. I usually fill up when less than a quarter of the tank is left (40 to 45L) to minimise filling errors.

If I drive it HARD, EVERYWHERE..... (Can't really mention speeds!)... I get at least 350 miles to a tank. That's foot to the floor driving, using every bit of 192BHP and 500Nm torque.
