Title: Remap to increase mpg?
Post by: Mako V12V on April 26, 2011, 09:55:16 pm
Is it possible to get a remap done with the primary reason to improve fuel consumption? Not too fussed about extra bhp (heresy on here I know!!), as I'm happy with the 227 the ed30 produces as an everyday car.
Are there tuners in NW England that can do this?

TIA
Phil

would the milage you do mean you would see a return?

just thinking £300-400 for the remap vs maybe a 10% increase in mpg...

just thinking out load..

With the extra torque of a remap you should be able to shift up sooner at low revs to minimise fuel consumption.

Did you choose the V12 Vantage based on it's consumption? :signLOL:

I had mine done at PD tuning, I get 29-25mpg whilst nailing it  :happy2:

There are companies out there that do specific economy maps however most maps increase your mpg because you have more torque.  :smiley:

With the GIAC flashloader you can choose from Stock,Race(100+octane),Pump(the actuall remap) and Valet mode which is a economical map made to just improve mpg.

Its super :)

My stock Pirelli made 27.5 mpg average first map 26.9 mpg average (1,500 miles) now with Revo stage 2 I am seeing 28.4 mpg, I do a fair amount of motorway as well

My prior car an E92 M3 averaged 20.3 mpg over three years. Both cars measure accurately against the tank. Revo told me that mapping for economy is not particularly successful, the problem being the torque band and spooling is at motorway cruise speeds, so riding the boost means less mpg

I stay in double figures on the motorway, if I 'cruise' at 70 I can see 31-32mpg average. The REVO seems better round town too for mpg

For a 2.0L it's not great but, it'll do.

Bit off topic but how does the power feel on stage 2+ compared to the M3? Much difference?

My gti did 11,5 km/l in stock and went down to 10,5 km/l with APR K04 conversion map. Now that i have the corresponding map from REVO due to higher lambda values (leaner mix) i'm back at 11,5 km/l. not bad considering a 76% increase in poweroutput  :notworthy:

Off topic, the M3 was notably faster than the Stage 2 between 5,000 and 8,750 rpm. less than that, say 3-4k I am not sure which would be quicker in a straight line. Push on and the handling of the M3 was in a different league, the car had genuine balance, poise and with the M button on, get busy and you realise why the parts list for an M car is long compared to a stock 3 series.

And the noise with eisenmman back boxes at 8,500 spine tingling.......

Will my Pirelli ever compete ?  Sadly not unless, I replace the engine with a wonderful high revving V8, push it way back into the shell, replace the suspension with something fundamentally better, etc etc. The M3 is £55k and the GTi £25k enough said

BUT catch an M3 in the wrong gear and keep the pedal nailed at 50+ on a straightish A road and you wonder where the £30k went. As the road tightens and you ask more of the car, you know !

If your doing motorway miles you would be better off spending your money on fitting the bluemotion golf under body aero trim to improve MPG rather than re-map, The bruce had a long thread on it but lower the car aero under body bits and pieces would help but only 10-15% but cheaper than a map.

Have they been proven to work? Im sceptical.

Not been proved no, but has more chance of improving fuel consumption at motorway speeds IMHO than a remap and the engine cover is £30 and provides additional protection from items entering the engine bay and sub frame as well.

this sounds pretty intriguing.... i'm doing about 300 or so motorway miles a week and this sounds like quite a good idea....

do you have any more information/links on this?

apologies for the thread jack:)

Did you choose the V12 Vantage based on it's consumption? :signLOL:


.... :signLOL: :laugh: :signLOL: Exactly my immediate thought!

@ Phil (OP):

C'mon, surely you enjoy that Aston V12 the most when you're on the throttle and mpg ain't got anything to do with it and shouldn't matter one iota. Otherwise is that splendid Aston in the drive just to impress the neighbours?

You mention a gain of 10 mpg and that's a huuuuge jump. Don't you think the manufacturers would have achieved that if they could? - It would sell them many more cars.

It's not great for the longevity of an engine to milk its torque all the time just as it's not great to continually redline it. If you're concerned about mpg then it's perhaps time to change your car - Diseasal? Remaps are designed to increase power and performance and more power always results in less miles per gallon.

I remember talking to you whilst at Miglior detailing, whilst you were having the inside of your windows
cleaned on your ED.  You mentioned the AM going back to Manufacturer for some work, Jay remembers it too, all ok?

All I can say is POSSIBLY... i.e. it could be possible...

I've had my Ed30 Revo Stage 1 for a week and have dropped 0.2mpg overall  and have had more "plays" than usual... On my journey to work I can still average just above 40mpg on a quiet run... I think more quiet runs and less plays I could gain a MPG or twoover standard...
