hi,

i have just recentlly bought a r33 skyline and my fuel consumption is so crap i may aswell own a fuel guzzling v8 or something :( .

the mods are- fmic, plum back greddy bov, rear muffler boxes replaced with jasma stainless steel ones, apexi pod style filter and everything else is pretty much standard.

im running it on shell optimax premium fuel and struggling to get past 350kms to a tank. and thats driving it like a granny.

im gonna get it serviced and change the fuel filter too and see if that makes a difference. but its driving me nuts, it pi...ng me off.

what do you guys think or do you have any suggestions???

please help

cheers

wow~ that is cool~~ been able to increase fuel economy just by changing the o2 sensor! what bout r34 gtt? is it the same way to increase fuel economy?

i think the O2 sensor will only increase fuel economy if it is not working.

i currently am running no O2 sensors because i am waiting on genuine ones. i'm getting terrible fuel economy on a brand new engine. it should do a lot more kms per tank once installed.

call petroject (now known as logicar) if your in melb. 9873 7006. i got an NGK/NTK o2 sensor from them today for around $100. direct fit, now gotta hope my fuel usage goes down from ~250km per tank lol.

how many litres are you classing as a tank? shits me when people just say "a tank" because a dodgy fuel sender can mean that it reads empty after using 35L.

put your economy into L/100kms. my 33 would get about 10L/100km on the highway and about 17L/100km round town because i drove a lot of short trips where it would still be on cold start enrichment, and when it was warm i would fang it a bit.

also you can get a direct fit replacement o2 sensor from repco, autobarn, etc. the new ngk catalogues have the part number listed for them. and if it doesn't just order the one for a n15 SSS pulsar as it uses the same one.

Thats impressive. 5 hours driving plus drifting all day on 1 tank? mine could never do that..
drifting is not to bad as most of the day is spent waiting in line :D, superlap or sprint style would not be a possibilty though. Athids s15 was one (FF cover car) http://www.skylinesaustralia.com/forums/ma...l&p=4478142

      RB25DE NEO with Haltech ECU

      If you take the top half of the intake off you can unbolt the flap off the shaft and leave the shaft in there blocking the hole. Then you can remove the little vacuum canister off from under the manifold and get a spare vacuum line to run to the ECU. I can take some photos of it later. Probably best to get the vacuum source to the ECU sorted first though. Mine all worked mint with the base map from the GTT an I've pretty much let the closed loop sort the fueling and took 1 degree out of the whole timing map.

      This IS something you also have to configure in Haltech (or at least I did in the past when going from onboard-to-ECU map sensor and an external MAP sensor in haltech land).

      I'm hoping it's something as simple as the ECU is looking for an external MAP sensor, but he is trying to use the onboard MAP sensor.

      You won't need to do that if your happy to learn to tune it yourself. You 100% do not need to do that. It is not part of the learning process. It's not like driving on track and 'finding the limit by stepping over the limit'. You should not ever accidently blow up an engine and you should have setup the ECU's engine protection to save you from yourself while you are learning anyway. Plenty of us have tuned their own cars, myself included. We still come here for advice/guidance/new ideas etc.  What have you been doing so far to learn how to tune?

      Put the ECU's MAP line in your mouth. Blow as hard as you can. You should be able to see about 10 kPa, maybe 15 kPa positive pressure. Suck on it. You should be able to generate a decent vacuum to about the same level also. Note that this is only ~2 psi either way. If the MAP is reading -5 psi all the time, ignition on, engine running or not, driving around or not, then it is severely f**ked. Also, you SHOULD NOT BE DRIVING IT WITHOUT A LOAD REFERENCE. You will break the engine. Badly.
