Hey guys

I have been trying to figure out how my stagea goes with fuel.

I have done my research and seems normally they should do 400kms per 60l tank.

I drive 80kms to and from work every day so I do 400kms a week. I fill up $70 premium every Monday and lasts till Saturday. Premium price varies obviously.

Works out about $14 a day for 80kms

What's everyone else getting. Does my figures sound about right or is my stag using a lol too much fuel??

You should talk litres per hundred to be more accurate.

Mine is a rwd with rb30 bottom end. To and from work 12ks each way uses 13.3 litres per hundred. Have been meaning to tidy up cruise part of tune for a while as I think it could be better.

I'm assuming your commute to and from work contains some freeway/highway driving?? 11.25 sounds very good...You have to remember Stagea's (S2 I think...dunno if the S1 or the M35 is the same) have a 68L fuel tank in them

On the other hand - check out http://www.skylinesaustralia.com/forums/topic/167866-stagea-fuel-economy/ - There is a discussion thread on fuel economy

S2 c34 rs4s gets 400km from 3/4 tank (have never run it into the last 1/4) if I drive like a total nana with only one or two slight boost moments. 350km if driving a little more spirited. Driving on the highway between adelaide and melbourne I got 550kms approx.

(I dont know how big the tank is to do ltrs/100km) but would assume its between 13 and 16 lt/100km average. Fair heavy considering the charger (with a 4.3ltr 4bbl auto) does about 15-17 lt/100km.. and it weighs about the same lol

Is there a system available for the c34 that can do the same?

Not sure, all the searches on Japanese Yahoo auctions searches came up for M35.

There are a few guys that can do the language conversion software, and the units are worth nothing in Japan, basically throw away $40 nzd. I guess it must link info from diagnostic software/on board computer to the nav screen?

Is there a system available for the c34 that can do the same?

Yes, it is called ECU Talk, here is a link for it,

i have one in my car, it is useful not only for L/100km but all other diagnostics.

can be used with a laptop and consult software to check for faults.

great investment http://www.ecutalk.com/consultlcd.aspx

S1 RS4V - does around 12.5-13L/100km "round town" ie Canberra roads. Country highway is 11-12L/100km, freeway is on the lower end of that.

Fuel economy improved ~1L/100km when I installed a hypergear hi flow turbo and a mv auto stage 2 shift kit.

Can't say scientifically which did what improvement, but my money would be on the turbo.

S1 rsfour, manual converted.

Only engine mods are rear resonator and big fmic.

14l/100km regardless of hwy or town driving.

Pretty much 100km per 1/4 tank or 400km/tank, I always fill up at around 350km.

ive found a noticeable change in fuel economy since having a stage 2 shift kit fitted to my S1RS4

Its possible, though I can't think why. The box runs a slightly higher line pressure, so if anything there should be more energy lost through the transmission. Perhaps not enough to make a difference on economy. MV autos said it shouldn't make a difference.

The larger turbo should be less restrictive and doesn't spool up at the whiff of a throttle. It now stays off boost unless Im giving some throttle over 3k rpm. That should be more efficient with the stock ecu.

Still, everyones results may vary. I read a post once saying that the stage 2 kit would effect the lock up converter, and I havent found that to be the case at all. Can't see how it would be either.

    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
    • Any going to watch World Time Attack at SMSP this year?
    • Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
