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

been written about a billion times before.....

Spark plugs, throttle body clean, afm clean and most importantly change your 02 sensor,,,, i didnt wanna spend $220 on a genuwine nissan 02 sensor so i just got a $60 EL falcon one from repco... i get 500km/tank now.... before was only only 300

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

    • As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.  
    • It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack. 
    • Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.
    • In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).
    • ECUtalk pages don't mention they support the ABS computer (consult port has more than one CAN), so you might just need a different scan tool. But, I would expect ABS is a different light to the brake warning/handbrake light, do you see an ABS light come on for a few seconds when you turn the key from ACC to IGN? But since you said: I'd have a look at the ABS sensors in the rear hubs to make sure they are not damaged, disconnected etc.
