Whilst on the subject of re mapping, (which I am considering) if it is so good to carry out the procedure for what is not agreat deal of money, why do the vehicle manufacturers not do it as standard. It claims to improve performance and/or economy, surely this would be a major selling point on a new vehicle. Or are there downsides such as increased engine strain and wear etc. that would make it generally unsuitable.
Are there any answers before I go down this route,
Thanks all, Dave
I am no expert on engines, but have heard/read that manufacturers have to design engines for world markets and some countries do not have the high quality fuels we have in Europe. Hence they have to set up engines to run in all conditions.
I am sure one of our resident re mappers will be along soon to give you a better answer than I can.

Trevor is correct in that fuels in other countries are not necessarily as refined as in europe.
Also the engines are basically designed for vans, vehicles that will hammer up and down the motorways at high speed for 1/4 million + miles or more. They are de-tuned to give longer service.
However, in a motorhome they are treated with more respect, are not generally hammered, and don't cover anywhere near the mileage.
You will do no harm to the engine by having it re-mapped, in fact you will probably find it runs smoother, quieter, and be easier to drive with more torque.

Dave, this is not an answer but I was considering remapping for my 2006 2.8 Boxer, mainly because the gear ratios, especially fifth, meant lots of gear changing when driving at around the 50mph mark.
I have read everything and had opinions from people who have had it done and all seems positive but I have one or two reservations.
Most, ( all ?) of the companies who do this seem to be 'small' even 'one man bands'. That is ok, perhaps, but guarantees of, for instance, re-installation if the mapping is lost for some reason, will only be valid if that company or 'one man band' are still in business. Remember TB Turbo ( and probably others ). You don't actually get anything 'concrete' for your money unless you buy one of the 'plug in' boxes which. opinion has it, are not as good as a remap.
Some companies claim "up to 35% increase in power". Check with your insurance company: mine would only accept up to a 30% increase.
Many people who have eulogised about how good the remap is, claim that the extra power will allow acceleration from lower speeds in 5th gear without needing to change down. That sounds good and is actually exactly what I was looking for, until you consider the problems that have been reported on pre 2007 Boxers and Ducatos with fifth gear stripping, seemingly due to it being rather flimsy and not up to the job. I wonder if some of those 'vans with stripped fifth gears have been remapped and 'lugged' in fifth. Would you *really* want to put all that extra power through that little gear cog? I asked myself. No I wouldn't.
This is all just my opinion of course, and I haven't had my 'van remapped, and probably won't now. I may spend a lot of time in fourth gear but I am happy with the economy ( see left ) considering that I also use the diesel for heating/hot water.
Oh! one other thing. A lot of the positive comments about the remapping were to say how much faster one could drive and how much easier it is overtaking lorries etc. on motorways ............. well, I don't do rushing, motorways, or getting there a.s.a.p. so each to their own ........
When a vehicle map is designes and all manufacturers are the same,they look at the whole world market place and at the worst fuel quality in what countries they are selling,they then instruct the ecu manufacturer bosch etc to install a map that will suit the poor fuel grades (for africa eg nigeria or uganda).this fuel is inferior quality compared to european fuel,the only way to get a modern diesel to run on poor fuel is to detune,unfortunately when you detune you end up with dead spots in the map and as anybody with the 2.8 jtd knows 60mph in top runs out of torque up hills,this is because there is a deadspot upto 2140rpm when the torque comes in.
We have our own designed bespoke modification for this engine giving 35% more bhp and torque,which is designed for a motorhome not a delivery van and has been fully tested in a motorhome for 6 months before it is even supplied to a customer.
The result
No More gear changing going up hills (less wear and tear on the gear box)
safer overtaking and pulling away from junctions.
better fuel economy
less stress driving the vehicle.
smoother engine running.
please feel free to contact me if you have any further questions or would like more information.
