I have mapped a transit tiper today for someone that has a fleet of 25 vans 4 tippers 2 navara's merc ML270.
His drivers are doing the same commute from york to retford and in the 2nd week of being remapped are saving half a tank of diesel..
He check's his vehicle's brim to brim and tell's me what savings he gets.
If anyone doubts the above i will gladly post his email add so they can ask him.. :)

Why not get What Car or Autocar or Which to do a proper scientific test and then even I will be convinced. Till then 1000 bits of anecdotal evidence prove little. Conditions vary, drivers vary, traffic varies, temperature varies, aircon on, aircon off etc etc.

Hiya Mark, if your not getting better fuel economy then get in touch with whoever mapped it for you and they can put a new map on..
And as for fuel saving bryan evolutionchips guarantee an improvement...:)

I'm not saying I'm not happy - I am enjoying the extra mid range torque. Just stating that some of the claims for significant MPG improvements could be misleading - certainly in my case it looked good on the readout but not in reality.

I had a remap done on my scenic diesel, It did feel faster but it make the mpg reading 15% higher then before and i found there was no benefit in mpg at all.

Take it back to the company who remaped this for you

Not forgetting once re-mapped the driver may "enjoy" the extra performance, thus negating any economy inprovements...

hawk20 - MB do indeed spend many £ks on R&D but as has been stated many times the engines are detuned to a extent to allow for less than optimal servicing and fuel quality, giving them a degree of in-built safety.

Also to get past noise and emissions tests, most bikes are flat ~5K revs to meet the noise regs, my Ducati went a lot better once it had new pipes and a chip (genuine Ducati CHip & Termi's).
Mercedes do it themselves with the Brabus chip so there is obviously some benefit.

If VW cannot fix our Caravelles economy (~25mpg average) I will be looking at getting that chipped.

A noticeable saving can be made by just turning off the air conditioning, not to mention the power boost.

not a chance... too busy in-fighting and plotting the new Porsche brand :rolleyes:

I know it has been stated by those with an interest in selling chips but IMO it is rubbish. Chips cost tiny amounts once the R and D has been done. The same quality fuel is avialable in most countries in Europe. If MB and BMW could really improve fuel economy by 15% just by a simple remap, don't you think they'd do that?

The new diesels after 5 years of development and 3 million miles of testing don't achieve that kind of improvement.

Chips can add a bit to performance by bunging in more fuel. Fact. At the cost of more wear and tear and hence you get the warranty reduced on MB's to 60k miles. And you must tell your insurance company or your policy is void ('any mod that affects performance' or even for some 'any mod')

But 15% better fuel economy? Bunkum. If they could do it they would get Which, What Car, Autocar and MB and BMW to test scientifically and prove it and they would be so rich they would not be wasting time on our website.

What the chips do is alter the computer read-out and convince customers they have a great improvement. But as some have posted here do the tankful to tankful test and the magician's trick is revealed.

so, does anyone want a good discount on a remap just to settle this??? :)

It would settle nothing. Samples of one are useless. And there are too many variables: temperature, traffic, type of journey, how driven etc etc etc.
Give one to What Car, or Which, or Autocar and get them to do a scientific test. And if they prove your 15% better fuel economy claim I will buy 5 people from this forum one of the proven chips.

Indeed not. Any more than chip companies are renowned for submitting to scientific testing of their fuel economy claims.:D

I'm all for remaps & chip tuning, what I cannot stand though, is the way they advertise lifetime warranties & better mpg guarantees. If you ever get to read one of these guarantees they are not worth the paper they are printed on. I have never heard of anyone making a successful claim.

Oops...
I have never had a complaint that our maps are not doing what we say and me personally, I have not done a bad remap to warrant a claim...:)

I have no doubt about that whatsoever.
But there are more than a few remappers who are quick to claim they are fully warranted for every eventuality. Some even claim that if the extra power destroys the engine or gearbox, the warranty will pay for new ones.

The reality is that the warranties only cover damage that occurred because the remap was faulty, which is highly unlikely. If the damage occurs because you enjoy all that extra power and can't stop using it, tough. It is amazing how many people are driving around with remaps or chips who think that their engine & gearbox will be replaced if they blow up because it came with a warranty.
