Stagea Fuel Economy

[pixel8r]

check out our before and after AFR's !

How'd u manage this? is that with a SAFC or other piggyback ecu?

[iamhe77]

so, much better economy then?

Haven't driven a VQ25dd so I don't personally know.

Will check "official" numbers tonight/tomorrow

[nickcorr]

Here are the official numbers...

9 km/l (11.1 l/100km)for 2.5t AWD vs 10 km/l (duhh 10 l/100km) for 2.5 Di AWD.

here is the full list.

i'm quite heavy on the foot and i seem to get around 450km's out of a tank..

and i am running VERY rich (plops quite alot)

once the PowerFC gets installed it should bump that figure up a bit more

[Stooge007]

got my RS Four S down to ~ 10.5L/100kms of 95% highway (to the Hunter Valley), but averages out to around 13.5L/100km around town (air con always on pretty much)

not amazing, but not too bad

EDIT - pretty much 100% stock car

So these things have a 68L tank? Im getting around 400 per tank, or a bit less depending on how spririted I drive it

Also, contemplating a Power FC over an SAFC. Been told SAFC are ok, but not the best to do as it just messes with the true MAF/MAP reading. Take much to get a PFC tuned for economy and WOT power?

Might have to also try this Boost98

{edit} just found they also sell a new one 'Premium 100'

forgot to add, running on either Vortex 98 or Optimax

That's what im running until the new injectors come for the e85. I get the same economy on the 100 octane as the BP98 I used to fill with.

United are the only suppliers left I think.

oh ok i havnt noticed. can you feel any sort of performance gain? and is how much more a litre is it on average than bp98 which is what i use

It sells for around the price of BP 98, I run it to stop the ping I was occasionally getting. I am able to bump up the boost a bit more now, if I want.

According to United, the fuel is at least 100, usually 102 octane.

The standard ecu will probably loose economy with it, my mates XR6t did, due to the ethanol content.

[JZZ20]

So you'd reccommend the Boost98 instead for economy?

Dont you dare put a SAFC on a 26 unless your really stripped for cash.... Its not hard to find a power fc for that car. Do it once do it right. You;ll find many stag drivers get the safc sitc combo as they have an auto and are restriced to computer changes with out spending big coin

[JZZ20]

Like I said, I want a PFC over an SAFC

E85 would be best, and at 99c bugger the economy. Lucky the M35 has an 80 liter tank.

Where to get said E85 fuel? hehe

[pistol-pete]

United's have it

Works out about the same anyway.

E85 is 25% cheaper than PULP98 and you use ~20-25% more of it.... but it is much cleaner and allows for a much more aggressive tune

[pixel8r]

Hmmm, well for me it works like this:

More boost = = more boost = = more boost = poor fuel economy

I'm still getting a minimum of 13L/100kms driving to work and back (at least 40% of the trip is spent cruising at constant 50 or 60km/h - so not exactly heavy traffic). If I drive it how I like to drive it, its closer to 14L/100km. Not a big difference...and the driving satisfaction outweighs the extra fuel cost IMO.

ive been getting normally just under 500k's a tank, the other day though when i had to fill up id gotten 580....
