2011 Defender 110 Puma 2.4 USW Stornoway Grey

So, remap is what? 500 quid?

If you drive for economy after that - lets me optimistic and say you get a 20% increase in economy.

tank size for a 90 - 13.2 imperial gallons so at todays prices around £84 (140 a litre or £6.36 per gallon). If you averaged 28 mpg before, you get 33.6 post remap driving sensibly.

before: 369 miles per tank (har har)
after 443 miles per tank (yeah right)

a benefit of 74 miles. or 2.2 gallons per tank.

2.2 gallons is £14

cost of remap is 500 quid divided by the benefit £14 = 35 tanks of fuel to get that benefit.

so you would need to drive 35 x 443 = 15,500 miles to see the benefit.

This assume that you always drive for economy for those 15,500 miles, get that MPG (33.6), never tow or go uphill, and of course that fuel prices remain the same.

It's a no from me.

and if you buy it and run it for 100k miles or so then you are quids in. Cheers

1998 Defender 110 300 Tdi HT Alpine White

I would hope that most people would at least be planning on keeping their Defender for more than 15,000 or 20,000 miles, at which point it would at least have theoretically paid for a £500 tune. It's a good point, that custom remaps will more than likely see a better fuel economy, if that's what you asked for, rather than a chip, or preset tune.

My uncle until recently had a 2003 110 SW, which he used for commercial towing, and he splashed out big time getting a custom tune from Alive taking it to 220hp, which needless to made it go like a rocket, but because he wasn't all that bothered by economy at that time, he actually got less mpg because of it, doing a hell of a lot over the limit on dual carriageway stretches. If he hadn't had a leaded right foot, he probably would have got 35 or so out of it, but the temptation is always going to be there, especially with something that powerful, to use all of it, and so chances are you won't wreak the economy benefits out of it... 1998 110 300Tdi White Hard Top
