    Engine mapping is changing the control parameters of your engines ECU and by so doing can in some cases increase power output or improve fuel consumption. Some claim increased power and better fuel economy, though personally I believe you get one at the expence of the other. Is it worth it? The jury are out on that one, some swear by it others say a waste of money, some say your insurance is invalidated, others that it will fail MOT. You will not get a consensus of opinion.

    Now you have started something, get ready for this one to run for a while.

    Yes we have and yes it is worth it to us, smoother running more grunt, would not claim better fuel consumption but as I have got used to driving it I tend to go a bit quicker so that most likely negates and improvements.

    I had my 2006 ducato 2.8 jtd done some years ago by wow tuning and I can say that driving it has definitely been made a lot easier ,less gear changing and better acceleration much smoother drive and
    more responsive to driver demands. As for mileage I never worry about that if I get there happy:)

    Not for me, if it was designed to do it why wouldn't the manufacturers do it?

    Yes. Do it.

    Manufacturers don't do it as they have to do a generic map to conform to a multitude of counties different regs. Doesn't mean it's the best map for the engine. Just their corporate and economic best

    Always have - always will. Swear by it.

    and I find those that have had it done make the most noise about it

    not wanting to admit the money spent did nothing :D:D:D:D:D:D

    We remap a lot of diesels.
    Our biggest clients ? ......
    Farmers !
    Mapping out John Deere / MF / new Holland and others makes massive difference...... Especially to PTO power.
    Be aware..... Some generic maps are crap and will do damage long term.

    I think a genuine company would take it off and give you a refund if it was no good, that was certainly the offer that we had.

    Worst money I've ever wasted.
    Ignored all the warnings about clutch problems swayed by tales of more power and mpg.:rolleyes:
    Done by WOW.
    Original Remap about £300.00 new clutch within a month £500.00 another clutch within 5000 miles £500.00 another clutch after 5000 miles £500.00 cost of getting Remap removed and a new Remap designed for the vehicle approx £375.00. Add to that a reduction in economy by 2 mpg and we do approx 10000 miles a year.
    As you can see a very expensive mistake and one I would hate to see anyone else make without at least warning them of the potential problems.
    If you must have it done use a professional firm who design a specific Remap for your vehicle rather than these off the shelf cowboys.

    Engine longevity....a 'soft' engine will last longer than a 'performance' engine.

    I have read that some manufacturers do offer it-as an expensive optional extra :)

    got my sprinter 316 remapped 2 years ago , very pleased. didnt go for full power map just better midrange because i tow a car and at 55mph it was never quite on the power when it came to steep hills and i was always dropping a gear. economy wise its no worse , maybe a tad better but i put that down to fewer gearchanges. i get 24 mpg on a run with car and trailer , brim to brim . quantum remaps in slough did mine, involved desoldering the main chip from the ecu and writing a new map to it from their computer. must admit i was a bit freaked by the chip removal but the kit they have is amazing so there was no need to worry.

    I think its essential for 2.8 Fiat with the standard gearing as it takes away the 2000rpm flatspot and makes a massive difference to hill climbing. The difference is truly amazing but I dont think its neccesary on the 3 litre as the power spread is so large.

    Hymer used to offer the option of standard 127bhp and 145bhp which I believ was a remap.

    As far as I understand, as vehicles are distributed world wide, they build to the lowest common denominator fuel wise.
    I had my 2006 Fiat done by Wow, and before, it was dangerously sluggish overtaking, it's much much better now.
    As for fuel economy, it's down to how you drive. Mine is 3.9t.
    I can get 22 to 28 mpg.
    I told my insurance company and it made no change to the premium. Mine was remapped not chipped.
