Fuel

[Nastazia]

I put in $50 or 34L on Wed and got 250kms out of it - (run down to red light). I have an auto fairly stock 33 running 190HP on stock boost... Is anyone else in an auto getting the same?

[MacGuyver]

I've got an auto as well and manage to get 400km on a tank before I cave in and get some fuel, at this stage it's been sitting just above the 'E' for a while now. This is done on 'grandpa' city driving with full exhaust, FMIC, EBC, pod and piggy back ECU.

I used to only get 250km's from absolutely-full-tank to just above the 'E' mark. I just changed my O2 sensor and then I could reach the magic 400+ mark, then I got my ECU tuned and things seem to have improved a little more still.

cool thanks yea had my oxy sensor done 5 000km ago too

hay guys, i replaced my 02 sensor today with an NGK item, and i had a long discussion with the bosch guys down here in tas. THE EL FALCON O2 is not anywhere the same, but somehow it manages to work, the heating element is different, and the output thershold is different.

I have noticed a BIG difference in the NGK item, the sensor is simmilar to stock but has different inside parts. I also replaced the ECu temperature sensor, the car is sooo much better now, going to see how it goes with the fuel economy.

I also replaced the plugs gapped to 1.1mm and i have to change them back to .8. It deffinatly pulles better with .8's

how big is an r33 gtst tank?

i fill up around 270-300km and i get around 40L in

thou im running over 300hp with 11:1 afr, and hit the limiter constantly on most days hahha

Should be about 65L tank, and you should stop puttin that foot down so much man I got 58L in mine today, I did run it down bit more than usual.

ohh thanks for that pulp

i think i can push it alittle bit more than to 350km... my fuel gauge doesnt work the best so i dont want to all the sudden run out of fuel ahaha

[StuiE]

I get around 450km out of 50L with my RB30E+T only mods are 3" catback and pod, I'm pretty happy with that, it's f**kall, if anything more than when it was NA

I Just filled up my car for the first time with the rb26 in and only got 235 kms out of the tank!!

i was shocked my fuel consumption halfed from the rb20. Im still running it in so i wasnt thrashing it. Im running a microtech ecu, is something wrong? do i need to retune or is this the reality of an rb26 running 310 rwhp ?

It's the Microtech, it doesn't have closed loop (unless new ones do?).

closed loop? whats that?

Its the Lt 1200 model. running MAP

[StuiE]

The O2 sensor controls fuel mixtures when cruising, to give good fuel economy, The Microtech doesn't use this and is rich all the time, not just when when flogging it, not flogging it would still use less fuel but not as much less.

Arr ok. Interesting.. Wish i knew that before haha.

have spoken to someone else with a rb26 running microtch and they are getting mor like 300 km/tank heading back to rotomotion for a retune i think, unless anyone would recommend someone else who knows microtech well.

Hi guys,

I'm pretty new to the forum, so what better way to break the ice than to let you know how my fuel economy is going. I get about $50 worth out of 200-250k's, I'm yet to stretch my tank out to more than 300k's, but anything's possible

[Flash89]

well i have grossed out 525k out of my full tank. (THATS A NEW RECORD FOR ME)

[play r 32]

thats enough outa you Gordon, thats just not fair!

[FLYIN_HiGh]

I average about 400 km's to a full tank. makes it hard when the petrol price is $1.50/L. good to see its a little lower atm.

[Flash89]

thats enough outa you Gordon, thats just not fair!

why, lol, how many Ks you getting out a full with that RB26 conversion

[play r 32]

220km at the moment i think its still running too rich though coz that is with some conservitive driving and a little bit of boosting.

[fr0st]

play r 32, you should probably invest in a wideband sensor like this

Although you don't have closed loop, you should still be able to adjust your fuel maps so that when your cruising your sitting on an AFR of 15 or so to conserve fuel. Just get a mate with a laptop and go cruising

I'm guessing your tuner probably only did a WOT tune if your using that much fuel

EDIT: Just forgot, my record so far is 8.9L/100km with a fair bit of nanna driving. I got 470km off 42 L... gotta love the RB20

[play r 32]

Thanks frost thats a big help ill look into it.
