Excess Fuel Consumption

[bbenny]

I dont think I can get more than 400km on a full tank in my M35 - I have only filled it twice since I got it, but it is chewing a hell of a lot more than my C34 stagea which was modified - My M35 is 100% stock!

Maybe I need a tune...

try an injector flush and perform an oil change. while youre doing that, clean out the throttle body and change the spark plugs...... all that will probably help.

so far so good

used 1 bar of fuel and 165km atm

heading for 600

currently sitting on 6.7 increased from 6.6

Just filled my tank for the first time, I never fill it but now I'm commuting

67.22L of 98 Vortex and the screen is telling me 545km @ 8.1KM/L.

Now I just have to control my right foot

WWATTTT ? 8.1 damn thats pretty high

did u just reset?

[Angus Smart]

Danny mines on 8.4 atm

thats what mine went to when i just clocked about 500km's in one go at a constant speed of *** and only used 2/4-3/4 tank

[[[d a n n y]]]

fark 8.4 is not too bad

seems like the M35 is a highway car then not a city car lol

The M35 should only use about 9.5-10L/100 on the highway. Anything over 10L/100km (or under 10km/L) on the highway means either something is not right or your right foot is heavy/shaky. Make sure to put the tiptronic into 5th when sitting on constant speed because otherwise the throttle is too sensitive and the torque converter will keep locking / unlocking, which will end up using more fuel. For some reason using the tiptronic makes it less sensitive and will keep the revs low and constant.

The above is for a completely stock stagea. Depending on which performance mods you have it may do better / worse...

In my own experience, mine averaged 10.5-11L/100km on the highway when in D. Putting it in 5th using the gear lever gave me 9.8L/100km but I've seen lower than that since. I'll be doing another long interstate trip in about 5 weeks and reckon I should be able to beat 9.5L/100km this time.

I reset a couple of days ago as I've been doing a lot of f3 driving and wanted to see how driving on the f3 was using mostly automatic mode, just slipping into manual shift for overtaking etc.

I'm hoping to be more like 10+km/L once the ECU is remapped.

[BezerkR32]

i thought 400km around town was pretty standard. i havent done a long tip yet. im not fussed really, my vx commodore was lucky to see 300...

[pixel8r]

Note that the M35 holds 10 more litres of fuel compared to older stageas, so 400km on a tank in a M35 is worse than 400km on a tank in a s1 or s2.

I'd say 430-500km would be a more accurate average for the M35, although it does vary quite a lot depending on where you live/drive etc.

[[[d a n n y]]]

M35's on average of around 500

(thats what i am getting)

[Angus Smart]

yeah ditto about 500 around town.

p.s. that snow trip i did in 4 hours so perhaps a little heavy on the right foot eh. but if my maths is up to scratch.. i was doing 11.7L per 100km's

I thought I would revive an old thread

I done my regular commute from Blacktown to Tuggerah today and reset all the major efficiency and timing devices on the screen.

Here are the stats for my trip:

[bigmat]

You all realise if you change the letters around on the STAGEA it can become a GAS ETA

[zei20l]

do you know if you re-arrange the letters of 'bigmat' it spells 'shut the hell up'??

and ive just gone over 500km on this tank and the light isnt on yet

[Bis-e Bee]

GAS ETA, i like it!

But atleast I've posted up some stats, will be interesting to see my stats after the remap in it's current configuration.

It should be putting out more power and using less fuel, can't go wrong!!

Once we know the remapping works and is beneficial it will be time to get a turbo to GCG for a high-flow rebuild and supply the new turbo with the dump pipe to Envy Imports for change over.

I'm excited, I've also asked Envy Imports for a quotation to supply and fit a FMIC with 3" plumbing.

The ECU should arrive from Brisbane about Tuesday, I should have paid the extra and had it sent from Japan early last week lol

First tank of fuel in my Stagea and I've just hit 530km on the tank (which incidently only required 69L and was right on empty) and I'm about half way between empty and the quarter mark so I think I'll easily manage 600km on the first tank.

[GTR91]

That's really strange because I'm getting roughly 18km/L in my series 1

dude i wanna be you!! lol
