Chip or not to Chip


W Fairfull

Recommended Posts

Before you do anything, work out your actual fuel consumption to date, ideally over the last year or two, then you have a baseline to start from as this will give you the cost per mile. You can then extrapolate from this how much you would save for every 1% increase in fuel economy up to the maximum that the chipping companies 'claim' you COULD get. If a MINIMAL increase in fuel economy actually pays for the cost of the chipping in, say, a year, then it might be worth doing, however I would suggest that instead you'll 'enjoy' having the extra umph and use it, thus negating any possible fuel gain! *-)

 

Personally, the only reason I would consider chipping is if I felt I needed the extra power, but as you are currently happy with the power you have, it seems to be an expensive way to POSSIBLY get better fuel consumption.

 

The below article give some insights into chipping:

The other thing you should do is ask your insurance company how you would stand with them if you went ahead with it, as they may increase your premium.

 

I'm also assuming that your vehicle is now out of warranty as I certainly would NOT consider doing it on one that is still under Fiat warranty.

I have a 2009 Escape 664. I fitted a Energy tuning box to it a couple of years ago. This was put on mainly for a bit more torque when towing. As for saving fuel I don't think it's made any real difference.

The best way to save fuel is keep off the gas, The computer on ours shows 28mpg when pressing on and 31.8mpg when I am towing believe it or not because I am only doing 50mph ! There is also a vast difference driving into the wind as opposed to driving with it. Bearing also in mind that the computer is only a guide and if its like the Fiat speedo it's 8% optimistic, also bear in mind the tuning device is confusing the computer as well. When I done the brim test it has worked out about 26.5mph regardless whether the tuners on or off. So to be honest unless you want more performance, don't bother. I do think that that best way to save fuel is alter the driving technique not the engine. :-D

Hope this helps

Hi there,

 

I have a Turbo Tune DT fitted on my van, see link :-

 

http://www.energytuning.co.uk/ttpg1.htm

 

It is a very easy DIY fit and is reasonably priced.

 

When you change the vehicle it is easy to remove and fit to the next one

( might need a software upgrade, not expensive ).

 

It is adjustable for both " Torque and BHP " and you can mix and match

the settings until you find the one that suits you best.

 

The main reason was to get more " Torque " as i found any hills meant

dropping a gear or two.

 

Not any more, on the motorway i do very little gear changing now.

 

I don`t know if you know the M6 North but it now goes up " Shap "

without any loss of speed and in top gear no problem.

 

One advantage of fewer gear changes is better economy and realistically

i get approx 4 MPG more than before it was fitted.

 

That it worked out on brim to brim fills and not the computer.

 

Plenty on here will disagree but i have it fitted and i know the differences

it has made for me and i`m very happy with it.

 

Hope this helps

 

Regards

 

Graham.

A little off topic but we had a Land Rover discovery with the 2.5l 5 cylinder diesel fitted. We had it rechipped by a specialist and the increase in power and torque was amazing, especially when in higher gears going up hills. Driving became much more enjoyable. The downside was if you used this extra power and torque it used more fuel, not a great deal more. The Upside was drive normally and carefully and we got about 10% better fuel economy. But difficult resisting all that extra torque!! :-S :-S

Where do you feed the chip's in a 1990 Tranny? 8-)

 

I don't really understand your question (If it's a joke, then it's got me beat!), but, if you are asking whether it's possible to 'chip' the normally-aspirated diesel (or petrol) motor of a 1990 Transit, the answer is No. Technically, it should be possible to turbocharge the diesel engine, and the petrol motor could be tuned conventionally or turbocharged/supercharged for more power, but simple 'chipping' is not an option.

Derek ... I can't believe you took Dave's question seriously!!!!!! :D

 

It isn't where to stick the chips that's important, its where to put the vinegar!!!! (lol)

Quite easy, open up the air filter box, remove air filter, place chips in filter box,be carefull to push down chips and replace filter and cover, i.e. it is not advisable to put salt and vinegar on the chips.

Vinegar! Vinegar! on chips !!! A friend of mine informs me that only working class have vinegar on chips 8-)

Aye lad, we know how to enjoy our chips ... and SCRAPS .......oooooo ... might have to have a trip to Beverley tomorrow to visit our favourite fish and chip shop to get our 'fix'! :D

Why should anyone (other than the dreaded Fiona) deliberately choose to introduce drivel into what was clearly a serious technical thread?

 

Now you've confused me Derek :-S.................Where does the drivel go? ;-)

I'll tell Sue that :D........................she always has vinegar, I don't..............and I thought I'd married above my station *-)

Dave, don't despair .. remember you drink it (aka wine), so you do get your 'dose' of vinegar after all! :D

I have a 2009 Swift Escape 686 with a Fiat Ducato 2.2 100 250nm and am considering fitting a plug in deisel upgrade mainly for fuel economy as I'm realy quite happy with power I would apreciate any inpute

So, moving away from the drivel! :-) You have a 2.2 litre, 100HP, five speed, 7 metre long, six berth, Luton bodied motorhome that must spend much of is time flirting with its MAM of 3.5 tonnes. Frankly, I don't think it is ever going to be economical. One test scored it at 24.8 MPG, which I would think relatively good.

 

The only real way to know your MPG is to record the mileage each time you fill, and the amount you put in, and keep the results in a spreadsheet that records total fuel used, and total mileage driven, over time. You need to keep this up over several thousand miles, because due to the small differences between pump accuracies, and the angle at which your van sits while fuelling, the amount recorded to fill it will continually vary. Over time, these small inaccuracies even out, but on a single tank full cause large distortions. There is also the matter of varying road conditions, speed, and wind, to take into account. I'd say anything much less than 5,000 miles would be prone to such distortions. Forget the on-board computers, they are invariably optimistic.

 

On balance, I suspect the benefit of a proprietary plug-in tuning chip, on a van such as yours, would be negligible. If you really want economy, you need to lose the Luton and get a lighter van. However, that would cost far more than a plug in-chip! Overall, I think I'd just leave well alone, and keep your money.

Having read all of the above - vinegar an' all - I have never been an advocate of chipping but looking at the latest economy minded gizmos an improvement of around just 2 mpg would pay for the device in about 18 months- provided the savings were realisable and not swallowed up by a heftier right foot?

 

My 130 is fast enough with ample torque so a bit less shove would not be missed most of the time as long as it still pulled well enough uphill and with different settings I might - or might not - have a reasonable chance of finding a good balance?

 

The link is to the one that tempts me at the moment - any observations anyone please?

PS - The correct place to stuff the chips in Dave's case is in the driver - as long as they are still warm - cold ones go in the dog!

I did have a mate who replaced his 2.0 litre Pinto engine for a Cortina GT version in his 1980's Transit - then Turbocharged it - and gee didn't that go but the only thing it could not pass was a filling station!!

Don't know if it'll work in newer engines :-S..............but when I added 4 stroke to my works van I was quite surprised at the difference it made to my acceleration.......... and mean't I could actually hit 80 mph for the first time as indicated by the sat nav ;-)..............

 

 

For the sake of my license I stopped using it :$

Might be worth exploring with Fiat the statement "No wires to cut, simply plug in and drive keeping your vehicles warranty intact". Also worth checking with your insurer.

 

 

I would of course check officially and in writing with my insurer (comfort) but a quick phone call to them brought the thought that there would be no issue as long as an increase in performance was not deliberately obtained - difficult to prove or disprove methinks - and as my van is out of Fiat warranty as of Sept that is not a problem either.
