Car remapped

    Hi
    Considering getting my 2015 vw Passat 1.6tdi re-mapped. It’s very hard on fuel and was advised this could be a good way to help fuel economy. A crowd in celbridge do it.
    Has anyone any experience of getting this done or is it worth it. Got quoted approx €300 to get it done.
    Thanks

    That thing should be averaging nearly 60MPG. What mileage is it in fact doing?

    Yes 100% this. You need to figure out exactly what your consumption is. What does the car tell you it is, and then you can figure out the most accurate figure yourself by fill you car with diesel, drive for a week and fill again. Record the mileage you've covered between fill ups and the amount of litres of diesel it takes to fill and you can then calculate you consumption.

    If the car is drinking diesel then there could be something wrong, and a remap will never fix that.

    "hard on fuel" is a very subjective term. That car should do 50+ mpg all day long on the motorway but if you're hopping around town in it, stop-starting and doing low miles, then it could very easily drop under 40mpg. And a remap won't sort that.

    You would have to drive very sensibly to get that type of mpg day to day.
    Small diesel in a large enough car, I’d say high 40’s might be more realistic.

    Will remapping not damage the car long term? Surly it cant be all pros.

    2015 car, can you get the new software from the dealer? The standard settings are ok and cost nothing for you. If you feel that car is not for you (not enough power, bad mileage, etc), do not try to compensate that "error" by remapping. Just buy another car what is more suitable for you. Or if your car have a mechanical issues, just fix it. You driven 4 years by that car (if you are the first owner), you should know exactly how it works and what is the normal or what is out of the specs.


  • Registered Users Posts: 23,199 ✭✭✭✭mickdw


    The engine was never right for that car.
    If you like to drive on abit you will be dogging that engine alot of the time and will therefore never get good economy.

    Huh... I've been called many things in life but a cynic is new.. Bravo Sir, Bravo...

    I was only asking, I have a 2L tdi myself.
    Well maybe you will enlighten me? On the subject of remapping.

    Never seen remaps succeeding in getting any significant fuel saving. As above what mileage are you getting, and more importantly what kind of driving are you doing?

    I've remapped a couple cars and am going to do latest in next month or 6 weeks.

    Never had better economy.

    I suppose technically you could have a bit better by using the increased power under acceleration. ie same acceleration for slightly less revs

    In reality will you?

    Also don't forget physics. Energy cannot be created or destroyed. ie A remap is not magic

    I have remapped and gone further with all my cars since 2003. I kept them circa 5 years and I put huge mileage on them and never anything failed due to the remapp.


  • Registered Users Posts: 51,060 ✭✭✭✭bazz26


    I never had any problems with cars I've had remapped. There is plenty of middle ground tolerance between how the manufacturer tunes it and how a good mapper tunes it. If you decide to trash the car hard then I'd imagine your clutch and/or gearbox will have a shorter lifespan because of that rather than the gains made by the remap.

    What's the point of remapping anything so?

    To extend the d.i.*.k.

    Remapped one car in my time and when the engine was being replaced I was told that the 120,000 miler looked like it had done around 300,000-400,000. Never saved any fuel either.

    The best man to remap a car is joe power www.tdr.ie.

    He knows his vag remaps inside out , has a great reputation and wont push a car too far.

    Ive a chip on my car and it gets 6mpg more chipped from 120 to 150 and thats a generic chip not a custom remap

    Think about emissions. To reduce NOX , the car is set up to burn more diesel to reduce emissions. Reverse this and you get more economy.



    Then with more power it accelerates easier , holds its revs and doesnt bog down as much.


    A lot of cars were derated ie 140bhp to 120bhp for CO2 figures as well to get their VRT and tax figures down.By remapping you just bring those back to what they were meant to be



    On the other side you have the lads who push the car too far and will cause damage /wear the engine out prematurely


  • Registered Users Posts: 3,404 ✭✭✭corkgsxr


    I'v found you can have better power and acceleration and get same mpg

    I'v never had them improve mpg just driveability


  • Closed Accounts Posts: 2,249 ✭✭✭magentis


    Wouldn't your insurance company need to be informed too?

    Of course - power and efficiency are two cheeks of the same arse.

    Sure, because I bought the cars what is for my needs. Buy the right car and you do not need the d.i.*.k extension.

    You must have had a crap engine to begin with. I tuned a car from it’s standard 130bhp up to 220bhp from new. The engine was still perfect after 300k miles.

    I bought the right car for me, the remapp is a bonus and lets me get the best out of it. So you’re talking sh*te

    Yes.

    Lots of people prefer to make excuses than do what their contract of insurance obliges them to do however.

    For 90bhp you had to have upgraded the clutch at least?

    How do you feel about performance engines being mapped then :rolleyes:


  • Registered Users Posts: 472 ✭✭Turbohymac


    Remapping is a waste of good money and simply causes more issues than worth
    Your main problem op is that you have a very heavy body being powered by a 100 odd bhp engine..lots of those sized cars should have had the 2litre engine as standard.. it won't ever be a sports car but once it's well serviced and driven normally it should hit mid 40s mpg. At work we had a 1.6tdi estate 2011 it was quite good overall.. put your money into a good service and diagnostic check to ensure there isn't any faults..and forget chipping.
    As for actual mpg of any car..forget the onboard computer. Simply fill it Absolutely to the max with diesel till you visually see it at top of filler cap then reset your tripmeter.. drive as you normally do till you're under a quarter of a tank..then refill to max again and see what's on the tripmeter. Definitely most accurate way..
