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

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

[Bunta]

what power you making bunta?

retune

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

<{POST_SNAPBACK}>

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.

[Spook's_Skyline]

u could just tell us what causes bad fuel economy

[Ska]

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!

[hungry6]

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 found turning off my boost controller gave me extra kms a tank

i also found driving much more boring cause i never hit boost

[Rhinorebel]

Fuel is still cheaper than cold Coca cola!! Stop whinging, drive hard and have fun!!

Yeah but we also dont go through 30L+ of coke a week getting around town!!

[ImpulR33R]

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.

[Spook's_Skyline]

awesome

ill get my mechanic to check mine out!

[Squizz]

however since my mercury tune

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.

[R33S2]

No one has mention spark plugs, they affect fuel economy too, if your over 12psi a closer gap of .8 is recommened but your tuner should be on to that.

MY 2c

[Spook's_Skyline]

surely ud get misfire before it would affect fuel economy though?

[R33S2]

what I meant is that if they are old or incorrectly gapped it could affect the economy. the gap bit was just a guide line and a 2c suggestion.

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

[Tommyk]

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 ?

[Spook's_Skyline]

mate, id be happy with 400k out of my tank

ive just filled up with optimax tonite, ill fill up again when i hit 100ks;

[Tommyk]

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

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