    Hi I am tempted to have my Peugeot boxer 2.8 hdi 2005 auto cruise engine remapped , has anyone had this done and was it worth the cash layout, ? I am looking for a little more economy but would like extra power not ness speed. Roy

    Please can someone in the know answer your question and give a quick explanation of what remapping is? I've read of vans having it done but no idea what it means!

    "Remapping" is reprogramming the engine's management computer to change things like turbo boost pressure, amount of fuel injected and injection timing.

    This means without making any physical "mechanical" changes to the engine, one can change an engine's economy and power output and power delivery characteristics.

    It's most commonly done to boost power but unless the transmission (especially the clutch) is capable of handling the extra power, you risk burning out your clutch prematurely.

    Some vehicles are more prone to this than others. Many reprogrammers seem happy to take your money without warning you of potential problems.

    You should also tell your insurance company that your vehicle is now modified.

    In a word no it's not worth it.
    We had a £250.00 remap done by WOW on 2.8 JTD and it cost us at least £2000 in clutch repairs and eventual removal. Plus no support from WOW whatsoever refused to even discuss it.
    Plenty more power but less mpg.

    If you must do it find a specialist who design the remap for your vehicle rather than someone selling a one fits all product.
    This was the most expensive mistake I've made on a motorhome .
    Be careful . (y)

    A good honest answer above, sorry about your troubles Forestboy, but nice of you to warn others here now

    I am sceptical of a lot of expensive 'improvements' and IMOH people who have spent loads of their money don't want to admit they got it wrong, they will convince themselves things are better than before the spend

    With remaps, I do wonder how many are resold without the information being passed on to the new owner, particularly if traded in, then possibly driving with insurance issues if they have not been informed

    well ive posted on subject before and everyone has own opinions , but as mentioned above if its done by a reputable company and not just one of the generic cheap maps it can do just what you want... no connection with either of these but give celtic tuning a call and vantuner (martin) has a very good reputation on the ford transit forum.

    Thanks for the explanation. Now at least I know what it means.

    I have answered this before for other posts, I had our Bolero remapped last year at a cost of just under£300, I now get approx 3-4 mpg more overall, more torque from 3rd gear upwards, and best of all the engine is now much more smoother and quieter than before.
    The van is now much easier and more enjoyable to drive, with no effect on the clutch. Make sure you use a reputable company though.

    Thanks all for your very useful inputs, on balance I think I will go ahead and will have it properly remapped (not chipped) by black code ,they seem to have good reviews and have been in business some time ..rgds Roy

    I had my 2.8JTD done at Peterborough on a special for £149. Best money I've spent on the van. All the flat spots gone, less changing gear, much less noise and vibration, made it a real pleasure to drive. Did it improve my MPG, well between this year in France and last year, 1 mpg, so not worth it on that count.
    The most surprising one for me is it goes up on the ramps so much easier than before (y)

    That's a hellava good price Clive. Best I have been offered was £250 at Newbury motorhome show , but black code is a little more ,but they do have a years guarantee on your engine ..

    Can't think of their name right now but they are at most shows, it was a special deal they had from the company who provide the mapping, they had 20 at that price instead of their usual £299, I know they did it again at Newbury.

    I thought about it for my Ace Adventurer with the 2.3 Fiat Multijet motor, I couldn't decide between a tuning box or remapping. Eventually I went with the tuning box from DTUK who also gave me a £60 discount on it.

    I told them I wanted more low and middle range grunt, (as opposed to outright power), and better fuel consumption.

    Was it worth it? Yes and no. I am not sure it is cost effective but I did get what I asked for and my fuel consumption has improved by 3 - 4 mpg so in that respect I am happy.

    With the DTUK tuning box, it comes set to a default setting for your particular motor and you can alter the settings for more or less power. The other plus is that you can transfer the unit to other vehicles and DTUK will reprogrammed it and supply you with the correct leads if you do this, so in that respect, it is cost effective and as future proof as these things are.

    I think that/was TDI at Newbury they quoted me £250 as a special ,but because I had a canopy problem after that huge rain/windstorm I couldn't take up the offer ..

    My instincts with remapping are if it really is that good why aren't the manufacturers getting it right the first time? 3 to 4 mpg better? Really? Fleet operators would give their right arm for that sort of economy improvement.

    As an example Ford had 200 engineers working on the development of their 1.0 eco-boost engine at a cost of hundreds of millions, is it likely some small outfit can produce better software to run the engine?

    But, at the risk of contradicting myself, I am sure engines can be re-mapped to produce more power but only at the expense of emissions and/or economy. It is the more power and better economy I find hard to believe. If it could be done the manufacturers would be doing it. Also claims from owners are, at the risk of upsetting people, very hard to substantiate. If you spend money on something which you think will give you something better then it usually does, but is it really or is it that you drive differently? :):):)

    BT who have one of the largest fleets in Europe remap all their vans.

    The usual response to 'why don't the manufacturers get it right in the first place' is, they are selling a product that has to work under extremely variable conditions ie wide ranging ambients, levels of maintenance, different styles of driving, unknown periods of use, many different uses, etc and it has to work whatever the conditions are.

    I'm also sceptical about multiple improvements after 'tuning'; perpetual motion comes to mind. I'm sure a few miles/gallon can be saved, as anyone who's tweaked an SU will know, but increased power output as well mmmmmmm.

    PN. It was Viezu Technologies, Bromsgrove that worked with BT to achieve improved fuel consumption for some of their fleet.

    I'd love to do it on my 2.8JTD, but I've heard of and read so many people who have had to replace their clutches prematurely :(

    I've also had people tell me and have read posts on Fun, that sing the praises of a re-mapping, telling of how much better they are, only to re-post at a later date, that their clutches have started to slip too and then eventually have failed :(

    Think I'll stick with standard :)

    I had all 7 of my vw t4 campers remapped all increased bhp from 102 to 140 which gave increased performance and increased fuel economy the vans are actually 140 bhp in Germany and are detuned for the British market i also decatted them as a diesel doesn't require the cat and made no difference to mot etc but a 5bhp increase and I also blanked off the exhaust gas return valve so only burns clean fuel instead of recycled

    All made a big difference and I'm planning to do the same to my Fiat lump at some point
