    Didn't work for my 2.8jtd, more power but very poor economy went from 29 down to 22 mpg. :cry: Now had it put back to original so back to better mpg which is more important than power for me. :Cool:

    2L diesel. Would not climb hills without lots of down shifting.

    Now it does.

    Same economy as long as I stick to same speeds.

    Hi Janet, from everyone I have met that has had it done I would say it can make a huge differance. My only reservation would be the fact that there have been plans oulined for chipping to be an automatic MOT failure in the near future. How much creedance we give to that ever happening I don't know, there are also tales of it invalidating your insurance unless you notify them due to the "increased" apparent BHP that is produced.

    How would they ever find out ? My husband is a tester and with the testing equipment currently in use it would be impossible to detect a remap. EOB diagnostic software has been talked about but that would only detect emission related faults. The same for insurance. There's no way of telling unless you decide to declare it, is there?

    To the OP we had our 2.4 rwd transit done prior to a French trip and our mpg dropped from 24 to 18. Loads of extra power but we had plenty in the first place. So we had it put back.

    Had it done last year on 2.3td. Driving hugely improved. Far more restful and easy. Much fewer changes down. Economy slightly better - well to be honest it drives so much better that we go faster now but at 55 mph it is definitely more economical. Our remap revealed a worn clutch... it definitely didn't cause it as they picked up the slippage and high biting point at the garage that remapped it.
    We're glad we had it done. It was a WOW garage by the way.

    had mine done by WOW 2.3 ducato

    Loads of extra power released, MPG went from 22 to 25 on the digi readout, didn't believe it, so my accountant wife made me brim to brim over 1000 miles.

    Digi reader was wrong, we were getting 25.2 mpg...

    Been well pleased, probably best £280 i spent.

    RE MOT problem? Take it with a pinch of salt, do an internet search and search on here.....

    Mulder said it- the truth is out there. :thumb:

    edit---- forgot to say 3rd van we have had done been happy with all, especially the 2-0l

    Hi Mags,
    Really interested in your post subject, and the results seem to be positive with most Funsters, please forgive my ignorance, but what is a WOW garage, I have been associated with the motor trade nearly all my life, but I have to confess, this one has me beat !,

    Perhaps review
    www.wowpower.co.uk/

    www.eliteremaps.com/ I used them for mine, Major supplier of remaps £150

    www.quantumtuning.co.uk/ Major supplier of Remaps

    Or just google remapping diesels...

    I do not believe there is a great deal of difference between the standard flashed maps for mass produced vehicles.
    They all seem to state the same figures give or take a few BHPs or pounds of torque.
    I believe from the research I did before spending out,that unless you rolling road and have an individual map written....save your pennies chose a national remap service centre. They all seem to say that if it does not perform they will put it back to as before, well mine did .
    I am really pleased with the performance change..Will see MPG this weekends rally trip Kim :Smile:

    A really good remap will have the original being downloaded via the OBD on to a laptop and the map file either send to someone to manually smooth it all out or done by the operator if he/she has the skills/training. I think that this is the way that most reputable remapping companies operate - it is different for each engine rather than generic for the engine type. A car club colleague of mine does mapping for cars and this is how they operate - same thing when I had my old Newstar remapped. Best money I ever spent on the van. However, as above, a more cost effective option would be a standard profile for each engine (say 2.3 multijet) since this would cost a lot less. If I had the Ducato remapped, I would go down the custom remap route simply because I know I can get it done via my contacts and probably pay the same as the above.

    I would avoid the plug in "tuning boxes" which simply fool the injection system. They do give more power but usually by increasing fuelling parameters

    How would the MOT Inspector or the Insurance company know that the engine was re-mapped?

    I can also recommend WoW for a remap. Had my previous vehicle a 2.3 Ducato remapped and was very pleased with the result. Also it worth informing your insurance company just for piece of mind. It does not tend to affect your premium.

    Useful full thread here.

    Having spoken to my expert, he has come across a number of vehicles that have been re-mapped and in his opinion its not worth doing, he said "There is no whay that you can improve on the MPG", he also suggested that in a number of cases the extra 3BHP is simply not worth the effort, any large increase in BP will certainly put strain on other componants and that could lead to extra repair costs.

    He further advised that the amount of research that major car companies invest in getting the thresholds right is vast, he then went on about the PSI and the nano seconds and pre-burn etc. I suspect that he may be right and any changed that Funsters see if any will be hard to prove as there are too many variables, unless you test the vehicle on a rolling road under test conditions.

    I am no expert but I am confident in my man and Rick from Motor roaming will know who I am talking about,..

    Sorry mate but your "source!" is wrong.

    I promise you, if you ever get in to a remapped motorhome following the work being done you will INSTANTLY recognise the difference in performance. Even Nikki can see that and she knows nothing about cars/vans.

    The person to ask the opinions of a remap is not im afraid your so called expert. Its me.
    No matter what take he can put on it technology wise I can put a take on it customer wise.
    1) My first fan was a 2-0D Ducato, fed up with overtaking lorries only for them to come back up the inside of me---Wild boy remap, lower MPG but I kid you not the van was like a super fast sports car.
    2) My last Adria, barely would pull the car, big van on a 2.8 JTD. sluggish but sensible. Wow tuning remap, result no change in MPG (marginal decrease) but if you could not get in to that van and notice the difference in overall performance and pulling power then I would of given you £100 cash and my house. The difference was stunning
    3) My current large 2.3 Ducatto Wow tuning again, done it, no difference, called them, back they came done it again, Startling difference amazing MPG increase for a change, and again, if you could not have noticed it when jumping in it then you simply would be mad.

    So lend your van to your source for a weekend, Then contact WOW, have it done, and lend it him again. I challenge him then to give you the same duff information.

    Unless you are confused between additional power V MPG?
    Some people do not see improved MPG, mainly because they are busy using the extra power.

    On the subject of MOT and Clutches, Im not going to comment, I would ask the OP to do a search in the forum for this.
    Some will tell you it will happen others will tell you it wont.

    I know where I bat from and said it many times, but what would I know im just a customer :Wink:

    Geo may have answered the MOT side but I can't recall the answer. However to find out what firmware is on the engine computer you have to plug in an ODB2 diagnostic cable connected to a computer and that computer would need the firmware details for every make of engine. I can't see that happening.

    We told Safeguard, no extra charge.

    Had my 2.8 jtd done by WOW very professional job, did highlight a knackered clutch which I was aware of. Performance was greatly improved especially on long hills and loads more torque but mpg suffered by about 2mpg but it could be me using the extra power as I do have a heavy right foot:Smile: For me a definate improvement and a much smoother drive well worth doing.:thumb:

    Paul, I did say that there would be no benefit in the MPG, performance is another issue, yes you can increase the BHP, but the componants that you van has may not have been designed to perform at those increased stresses.
    So you may well run the risk of clutch damage etc.
    Yes I Googled it and there no end of postings about issues with the clutch after re-mapping, that may or may not be linked, but on a new van you may certainly make the guarentee invalid.

    My expert is an expert , and Rick Motorroaming will back that up, they are small and very specialised, their Service Manager has over twenty five years experience working with the likes of Porsche and Ferrari, road and race.
    They have all the latest technology and diagnostics including Autologic Diagnostic System. It enables them to carry out "Full Dealer Level" Diagnostics, Coding, Programming and Tuning to a vast range of vehicles.

    Experts they are.. :thumb:

    No the expert is the customer, is all im saying, :RollEyes:

    That's me :thumb:

    3 remaps, no broken engines, loads more power.

    Motorbikes, 5 remaps, loads more power, no broken engines (even in early days)

    There is loads of posts on the subject, the OP has asked is it good or bad?

    How many above say they have had it, experienced it and its bad?

    They too are all experts, your ferrari porshce man can come back and comment when he has ran a motorhome for 8 years with 3 remaps not passed an MOT and suffered premature engine failure or component failure directly resulted to the engine remap. :thumb:

    I once had an Iphone,
    I asked a question about changing it to a galaxy,
    the experts with the iphone said the galaxy was rubbish,
    the people with the Galaxy were the real experts,
    they owned tested and tried it.

    I now have a galaxy,
    im now an expert on whether its better than the iphone
    or if not an expert,
    then a dam good source. :thumb:
    make sense?
