Yeah, but the question is can you ever fit 65L into the tank :P

I usually fill up before the orange light turns on, or just as it turns on. With the new fuel pump and upgrades, I'm afraid to even let it sit at the 1/4 mark - it's always above half tank.

Must get a tune soon :(

what power you making bunta?

retune :P

wifey wont like it;

ive already spent hundreds of dollars on tunes (switched exhaust, retune was another 300 on top of the origianl 600)

surely for that amount of money, it wouldnt just be a power tune :(

was done at mercury

Spooks I make 200 rwkw on the dot, However I think that having the RB25 in the lighter car (R32) would lend its self to better ecconomy, I find a lot of the time I am using around half the throttle that I used in the R33 for similar accleleration (R33 also made less power)

How could you not fit 65L into a 65L tank.

When the light comes on..you should be able to drive approx 100km more before the car will stall.

I'm just curious as to how people are measuring their distances. Surely you don't just fill it up and then read the odometer when the light come on.....that's just silly.

The only accurate way to measure the right distance is to fill it up completely to the brim and then drive 100km. Then pull into the nearest servo and fill it up to the brim again. Note down the number of litres you have put in....it's as simple as that.

The car is heaviest on a full tank so the fuel economy is its worst when the tank is full. Don't cain the crapper out of it for 100ks either, and don't baby it...just normal driving...boost it regularly. Then post up your results. I am willing to help those in need but no-one has taken me up on the offer yet.

The only reason I suggested the tune was because on my old r33 gtst I was pushing 300kms out of a tank, thanks past the light and waiting till it coughed.

Anyway I bough a SAFC and took it into Mercury for a tune and BAM gained 15rwkw and consistently got 550-600kms out of the tank!

My problem is that the skyline only get driven hard. If I was going for fuel economy, I'll just drive the office prius, it get over 1000k/tank and take 500 metres to stop from 100k/hrs. Tyre are as hard as Steel.

But if you have ongoing bad fuel eco, get a smoke test done and a good tune will fix all. but $500-750 in difference of fuel eco, buys alot of fuel. Oh wait I don't have to pay for mine.!!!

I had a similar problem with bad fuel economy and fuel smell.

I traced the problem back to the aussie fuel filler/nossle from the compliance process. seems the dodgey bastards hadnt fitted it properly and it had become slightly loose and alot of fuel was evaporating whilst the engine was running.

I simply removed it, cleaned it down and used a strong fuel rated sealant such as sikaflex. I got alot better fuel economy and lost the fuel smell.

Hmm maybe a SAFC is the way to go.

I have a stock GTT and was getting 400-450kms (mixed city and freeway) before the light came on, a few months after now getting 350 to maybe 400, pure city driving though. Dont know whether this sounds right but I do know other GTT's, especially modded ones are getting more. I drive OFF boost almost 99% of the time.

So yes, Id like to know whether there is a fix for this? perhaps a SAFC might be the way to go. Ill also chuck it on the dyno to see how the figures turn out.

That's deffinetly the best way to measure your fuel consumption, i did a couple of Thursday's ago had 11 pound, 35k's highway the rest was fairly spirited, pulled into the servo and got 12.3 L i was pretty happy with that, is this more what your trying to get spook's

within the powerfc, drop the injector duty cycle down by xx %

remember, it will run leaner across the board (so more knock, perhaps?), but is the easiest way of 'retuning' it without taking it to a tuner ?

Anyway, i couldnt be bothered reading all the 3 pages, so it may help ?

Or drive it off boost. with my car i managed 450 city kms when keepin it under 0.2 bar of boost. boring as hell to drive. Mind you the other day i ended up going for a bit of a thrash and did 200kms on a tank (whoops)

oh and managed to chew up most of the fuel when i was at oran in under 100kms :P

happens when your duty cycle hits around the 92% mark on 700cc injectors

    • The German place in Cabramatta was rock solid, fresh pretzel cooked to order back then. Then it went all quiet, after all the poker machines were removed, then I believe it closed for good. I did drive past the other week and noticed outdoor lighting a big screen, but no idea what is there now.  
    • Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.
    • I would say no, why, because my daughter, who also lives in Goulburn, hasn't recommended us going there Pity, as we miss all the German joints around in Sydney, actually, the restaurants are the only thing I really miss about Sydney, and a special mention to Ishibanboshi at Bondi Junction, their Kara-age Don is heart cloggingly deliciousness (always added a special boiled egg...or 2) 😋 
    • Does that German restaurant still exist in the old place out the NW end of Goulburn? When I say "out the NW end of"...I am really being vague. It was 1997 when I was last there, and the only point of reference I can recall is that it was on the opposite side of the main drag from the big merino. And when I say "opposite side of the main drag", I don't mean "on the main drag". It was either a couple of streets back from there, or might have even been out in the sticks a bit further. Was an old farm building or mill or somesuch. And when I say "the big merino" I might actually be thinking of a completely different part of town, because I just looked on maps and the big bugger is not where I remembered him to be! The food was good, consisting largely of various German mystery-meat sausage/loaf things and kartofflen.
    • So while the second sentence is completely correct and the whole point of the conversation, the first sentence bears consideration. If this bloke is just hoping to throw big turbos on and drive it around, because there are no helpful facilities at all in his tropical paradise** then he likely has zero chance of even knowing what the TP is on the last column in the stock maps, let alone know whether the ECU is operating anywhere near it or past it. So the point is very very moot. And, per what I said before, at stock boost on those turbos, you may well be off the end of the map. **I'm just back from Vanuatu, so I know exactly what small Pacific nations can be like wrt paradise without requisite facilities. But it's not even that simple. I put a high flow on my car and had to drive it around without a proper tune because of the lack of opportunity*** to put the bigger AFM and injectors into it to allow it to be tuned. I had to turn the boost down to less than I had before, and back off the boost controller's ramp, because it was exploring parts of the map that it didn't drive in before, and really couldn't access for tuning on the dyno either, and so was pinging. It was still well within the last column, because when I first**** set up the Nistune on the Neo I rescaled all axes of the maps to give some more space to explore. ***Family dyno was broken ****This was 13 years ago, and the TIM thing wasn't a thing then and so TP would definitely grow when pushing past the stock tune's limits.
