What should i set my dccd on to get maximum mpg?

thanks

[W1 KRB]

Might be completely wrong but can't see as if it makes any difference at all!

[Dayo]

iv read somewhere that you shoudl set it to most power at the rear?

[WR 1mposter]

Without trying to be arsey Dayo, so please don't take this the wrong way, why buy a car that does fook all mpg if fuel comsumption bothers you that much

[Dayo]

It doesnt bother me what it does, i just wondered whats best like when your on motorway etc?

[WR 1mposter]

Auto !

Dayo
You stated in a previous post that the car was good on fuel? i do believe i stated i got 77 miles on just above half a tank and a tank of fuel would be consumed in about 236 miles. You drove back from scotland and got 300 plus and still quater tank left? Someone then stated they were WRX figures and you may have a different engine fitted???

Ive just managed 240 miles on a full tank of v power and that was driving with care, so your engine must be under power or as stated a WRX

Quote me if im wrong

I was regularly getting over 330 miles on a tank on motorway runs.

I was regularly getting over 330 miles on a tank on motorway runs.

Well ive just done a round trip from Swindon and back to Birmingham and a tootle round town, 240 miles and that was driving sensible??? no racing no 0 - 60 in 4 seconds and so on

Mine must be fooked then

If it's not already mapped I'd look at getting it done.

Mapped? The car is like a rocket now so more power less fuel consumption.

Good fuel consumption less power?

Just passed mot so emissions ok not over fuelling.

Would be lucky here to see over 230-240 miles on a tank during careful motorway cruising. Easily demolish a tank of Shell's finest in about 30 mins playing at full chat with ALS on.

I would guess to max mpg, you need to minimise transmission losses so sending power to fronts would seem best. Cant see it making sod all difference really.

A remap however would defo ensure you have optimum for fuel usage, both power and Mpg, but seems like you get more than most anyways.

So those cars getting 300 miles plus on a tank must be running so lean and a good bit under power in my opinion, or they have a WRX engine not the standard WR1

So mines not fooked then and running correctly

[W1 KRB]

I'm doing a 250 mile round trip from Bedford to autotecnica Derbyshire tomo so I will brim the tank before I leave and see what I get with "normal" driving, I'm not gunna do an economy run but just be sensible on the throttle, if I get there and back on a tank I'll be happy with that, can't see it personally though.....

[MUNK]

this has been a debate for a long time...surely just comes down to car being mapped or not??
either that or incorrect turbo for car?? ibought mine knowing it was a guzzler
if i want good mpgs i get on my bike!!
averages per tank do seem to be 230 240 mark....

What should i set my dccd on to get maximum mpg?

thanks

Didn't you get 335 miles on 3/4 tank? if so, the only way you'll get more mpg than that is by turning the engine off and pushing it everywhere!

Don't think the DCCD will make any difference, you're still thumping out the same power regardless of which wheels it's going to. Relax, get used to 18mpg and enjoy the BOOOOOOOOOOOOOOOOST!

Yes Dayo did state the above, so he would in theory get 400 miles to a tank......

I to wouldnt have brought the car if i was concerned about fuel, not very environmentally friendly

This mapping? how can this improve fuel consumption, surely you will be increasing power output if you have this done? more power more fuel or is it to get optimim fuel econemy, if so better fueling must = less power

Fully open, lowest setting green on the dashboard. Does make a bit of difference but not enough to warrant the hassle of flicking the manual button every single time you start the engine. I know people that do it and claim it gives 3-4mpg but its hard to tell without a proper independent test.


My standard car would do 230miles on motorway trips to 1/8 of a tank left. It would do 160miles in stop start rush hour traffic. When having weekend fun on B roads it would do 180ish per tank given im out of 1st/2nd most of the time unlike rush hour. Track days I would get from 55 to 75 miles to a tank keeping the revs above 4.5k most of the way round the track to keep on boost.

If you want economy buy a third car as a daily driver like I did. Megane sport 225, 33mpg on motorways, 27mpg stop start and nippy - 5k

I actually tried the wifes Mondeo ST TDCI to work and a couple of courtesy cars on the daily stop start commute and found even the smaller engine diesels LESS economical in stop start traffic than petrol cars for some reason. Motorway journeys would be a no brainer but I dont do much of that on the way to work. In fact the most economical cars for me on a rush hour tend to be the 1.6 or 1.8L hire cars that dont struggle on the hills like the 1L rubbish and not as heavy as the 2L+ cars.

[Gary75]

So it seems most are getting the average 240 miles per tank. Which leaves me with one last question, if your getting over 300 miles on a tank plus or Dayo's car getting around 400 miles then your car needs the attention or a remap whatever that does? retune etc.... those good on fuel WR1's must be down on power, big style
or they have a fitted wrx engine with very small turbo say 265hp.

[huzzy]

Nothing wrong with my WR1 when I had it. Just sitting at 60 on the motorway is at the peak of it's fuel consumption.

In the time I had it I done 10406 miles at an average of 26.61 MPG peaking at 29.44 and the worst at 23.18.

Bit different to my car now which I've peaked at 28.55 and the worse at 16.35 over a tank!

[asperformance]

even small turbo cars/wrong engine/etc. will struggle to see those figures............

best i have ever seen (Fozzy turbo AUTO) was approx 42mpg on a very gentle ride around Scotland - but same car door to door struggles to do 20mpg

[Crockel]

I think in the 3 years of ownership I have managed a little over 250 miles on a tank at best - that's when I tried to drive as gently as possible.

I think claims of much over 300 miles on a tank need to be taken with a pinch of salt. It would suggest that the map has been changed,or the engine and/or turbo changed or someone has fitted a much larger tank!

Driving as slow as 60 mph on a motorway takes some serious willpower as well as being plain dangerous on most motorways I have driven on

[huzzy]

My iphone app doesnt lie. Believe it as much as you want, I have nothing to prove by exaggerating my fuel consumption.

My Spec C on a gentle door to door motorway run does 28 MPG and that is running 330/350. Stay off boost and it's easy to do.

Again that topic suggests around 240 to a tank and less.. I would get your motor checked along with Dayos super duper 400 miles to a tank car? Megaman again suggests that you are getting wrx mileage from your car? Might be worth checking engine numbers or running on a dyno?

[SteveS]

I am running a standard unmodded 2003 blobeye WRX which returns 260 miles per tankfull on a regular basis and has done since i bought it in 2005, had regular services at required intervals. My WR1 i have owned for just over a year, gives 230 miles per tankfull over exactly the same terrain, I alternate them both for getting to and from work. The WR1 is driven harder than the WRX as you would expect on fairly clear straight A roads. I recon the WR1 is right on the money at 230 miles per tank.

My WR1 pushed out 312 bhp on the rollers which I was impressed with as it was standard. My new car has been mapped twice and been on the rollers twice since January. Think I'll leave this thread now as obviously I'm wasting my time.

I suppose the thing to check here is when people are filling up. I have only ever seen my low fuel light on once and would fill up when the gauges shows 1/8 of a tank. Driving at the most economical speed would be 50-55mpg at a guess as you need to be off boost and have the least wind resistance. Maybe if someone has the patience to drive at 55mph for several hours it will do that mpg. All I know is that my car when standard did the mpg's above with my driving style. The 2.5L engine does better mpg at the same power levels due to more torque. The 2.0L WRX that my brother in law had would do 300-325miles to a tank on a motorway. This matched figures that John Mc Tiddler (Dogging Expert) quoted he got from his car but when we investigated his car it was found to have a wrx turbo and I assume a map or ecu to suit. At the end of the day we dont buy these cars for an economical run about we buy them for smile and thrill factor.

[Ant]

My WR1 used to do over 300 on a run and no it was not down on power as on rollers it managed 322 bhp.

[chiroman]

A few years ago I looked into getting more mpg by having an economy map but was told not possible as although you could run a lean map as soon as you booted it, it would be too lean and ECU not able to respond adequately and engine kapput!

Bob Rawle advised just run off boost ie approx 2500rpm max which is still a reasonable speed on the motorway but in the slow lane.

At the time I was using the WR1 80mile daily drive of mainly M25 and some B roads and would fill up to the brim each time.

So did the economy run out of curiosity, keeping off boost, achieved 29mpg, I think about 65mph in the slow lane of the M25, which wasn't a great experience.

Although this may seem reasonable mpg if I had to drive like that every day then why not get a turbo diesel and achieve 65mpg! My neighbour just bought a new BMW 318d and gets these sort of figures.

The economy run lasted for a week, which was torture and pointless for a WR1 and I went back to normal running in the fast lane 80-100mph and about 22mpg which incidentally is about the same as my Ford Cortina 1600 from the dim and distant past.

When I first got the WR1 nearly 6 yrs ago I didn't expect it to be economical but it was a bit of a shock with 16mpg across country.

The turbo Impreza isn't a lean burn motor even off boost which is a pity, but as Mike Wood said "it's all in your right foot".

I've never worked out the miles/tankful as I fill up each time which is more accurate. Just note miles since last fill up, litres to fill up, get miles/litre and IIRC divide by 0.22 to convert to mpg. the ans is between 16 and 22 so why bother.
