OK, a sensible question from me for a change:

We all know about the remaps for power increases, all well and good for those who have shares in Toyo and Sachs.

I would like to know if there is such a thing as an economy remap - keep the 130 brake figure but improve efficiency and get better mpg?

The insurers will like it and so will the wallet at the pumps........

I have just been for an interview at a well known engine manufacturer and want to get the best possible mpg if I get the job as it is 60 miles away. Although I did get 70.8 there and back today.

Most remaps give you a gain in MPG, but IIRC you can get more Eco friendly maps.

Thanks for that mate, I will search the web.

We normally see a 5-8% saving on fuel, We have been working for a while on eco tunes, as we do alot of trucks for this reason. And we can see over 12% saving and an increase in power of around 30-35 bhp

What's a remap, how much do they cost and can you do them on all cars?

I have a 1.4Mpi with legendarily bad MPG (about 27). Have considered adding LPG before but bootspace is part of Fabia appeal, so any other way to get more fuel out of the bugger (live in Sheffield too so hills take their toll) would be appreciated.

Have you heard of chipping a car ???

Well it's the same sort of thing, without adding/piggyback a chip, your engine map is rewritten

Are companies able to remap engines to produce less CO2 as well as for improvement in fuel economy?

I own a 1.4TDI 75 which apparently produces 124g/km which just puts it in the £120 a year tax bracket.

I have heard the new 1.4TDI 80 has low enough emissions to get it under 120g/km and into the £35 a year bracket.

Can a remap be done to lower CO2 emissions and the car re-classified and re-tested or is it a little more complicated than that?

Am I also about to find out that the cost of achieving something like that would be far more than the money saved on tax, unless I keep the car for a zillion years?

Cheers

Sadly, although you could get the MPi engine remapped if you really wanted to, it'd set you back hundreds of quid, so may well not be offset by the fuel you save.

What I would say, though, is that my wife has a 1.4 MPi, and we see about 31-32 mpg when she's driving, but 36-38 when I am. Although this is going to come across as anything other than a put-down on her driving abilities, you can do an awful lot to improve your fuel economy by just driving better...

Then again 27 mpg really is quite bad. There might be a couple of things worth fettling to see if you can get an improvement 'mechanically' so to speak. A fella called Fabia1.4 had similar problems with his. Try searching for his posts to see if you can get any pointers...

sell the 1.4 mpi and get a diesel!!! The CO2 is done when new on the manufactures figures, not sure if you can sort this out later on

I was thinking along the same lines. Clearly I've not looked into this in much detail but it's worth thinking about the following:

Remap cost is about £400

Improvement is around 10% in real life (going on above)

Say you put in £40 in fuel a week, you're effectively going to save £4/week

So it's going to take 100 weeks before you see a return on investment

After that, you're going to see £200/year saving.

All well and good these remap claims of improving MPG's, i have done two different cars in the past and both gained in power but lost in economy, which truthfully i would expect...more power=more fuel being burnt.

i think this talk of a remap improving economy is good..

it's a good way to justify to yourself/wife/accountant etc why a remap is

the way forward with a "side effect" of more power.

similar reasoning is the need to buy a bigger tv to reduce eye strain and save on

the cost of reading glasses in a few yrs time..

So all you remapping experts out there, can one of you please answer this:

Is there such a thing as an ECO remap? - little in the way of power, lots in the way of efficiency improvement?

(If a remap makes better use of western fuel quality to get more power, surely it can use the same to improve smoothness by improved burning of the mixture and thus improve economy? But now I have answered it for myself - if it burns better it will always make more power, correct?)

I have had exactly the same experience and don’t know anyone outside Brisky that has seen improvements in mpg either:confused:

My old man got his Mk1 Octavia remapped. Dont know what to, but i have been in the car with him on a 40mile trip and seen him get 46mpg!!

Where as he could only get about 39 before the remap.

He does drive like a grandad now tho, but even so, 7mpg more out of a 210+bhp octavia aint bad!

i get worse economy too since the remap.

After a full service and, as suggested, examining my driving style, I'm up to about 30-31mpg now. Still don't think this is good enough in a 'modern; car tho. Mpg does spike sigbificantly when driving at higher speeds though, so maybe MPI just not suited to around town.

Econotune Carlist

After a remap the economy will improve IF you change up into a higher gear earlier because of the increased torque post-remap.

Most folks don't notice any economy improvement after a remap as they are too busy using the extra power

Interesting bit about lower emmissons in the new TDI-recently DVLA were running a prize draw if you tax on line with prize as Seat (leon I think ),but 1.4TDI quoted as 99g/km - putting it in the £zero bracket -same engine /setup as the new 1.4tdi??

Edit -just found the reminder -was an Ibiza 1.4tdi

Eek a beak!

I've got a 2001 1.4 MPI and the only time I get MPG like that is stuck in very big traffic jams with the aircon on.

Normal 'busy but not static' journey to work gives me around 41 MPG, busdy traffic and that's down to around 36 MPG. Tootling down to Staffs on the M6 at 70-ish (from Merseyside), returns around 48 MPG, if I'm more careful with the ole right foot and keep it around 60-ish, that goes up to around 54/55 MPG.

Before anything else, I'd suggest getting you car checked out as that seems, well, crazily low.

You lost power prob because you drove it faster and harder because you could.

If you have a good remap done, and drive normally you will get better miles per gallon.

BUT... when you do push it, you will drink more fuel then before, and so if you do a bit of normal, and a bit of FAST... it will even its self out to the same mpg as before, doing the same driving. So there is no way to justify a remap for fuel economy.

The only way to justify it is... that it makes your car a heap of fun to drive.! Simple.!

Get it for that reason and that reason only.!!:D:D
