HELLO i own a R34 coupe 2.5ltr neo, tiptronic auto ewww, has a K&N air filter, removed the cat, new iridium sparkplugs, well serviced only done 100K... the problem is i fill it up at $80-$90 right to the top about 60ltrs i think and it only goes as far as 400k-430k depending on how i drive it!!! ive had it hooked up on the scanner tool and all the sensors are fine. thinking of some performance chip in future aswell but not if it going to drain more fuel and yes i will be getting and exhaust extractor and putting a manual in soon .. the point is that i should get 100km to 9.5ltr-10.5ltrs of gas.. any ideas if there could be something else wrong...cheers

hey mate i have a r32 gts-t and i do about the same from a full tank. i always refil when i have 1 quater of a tank left and i have usually done about 330kms by then.

so yeh i think thats about normal.

Ive got an R32 RB25DE

i get a little less then you normally..

BTW if you do a search theres 11tybillion threads on similar topics

yes there is heaps of threads on this but none to do with later models, i have heard about the vct on the neo heads can sometimes put the timing out

just thinking out loud here.

seems like the NAs no longer get the fuel efficiency they used to. wonder why?

back when i first got my car, i'd get 500km+ easily... 600 when i took it for highway, easy drives.

is it the fuel or the age of these cars? two of my mate's gtsts (one is stockish, runs high 13s. one has 250+rwkw, runs mid 12s) both get something like 400-450km/tank driving off boost.

Funny, mine did the opposite. When i got it it was getting about 330-40kms to a tank (9km/l), and now i'm getting around 600kms. The only thing i changed was running V-Power for a while while it was cheap, and then kept running vortex or Unleaded 95 from shell.

i got about 480k's out of my last tank of v power racing... the fuel light was on and off for like 3 days... never been so scared in my life! :blink:

i normally aim for 400, my needle is pretty low about then, but theres still about 15litres left in there...

im running a GTS-T though, and often run it boosted...

woah thats incredibly depressing...

i get around 500k's to a tank average driving with my beast :blink:

your economy is not normal people, maybe professionally clean injectors, new 02, clean afm, make sure the engines in good service and tune (plugs, timing) check compression... no exhaust leaks? smash it on the dyno, check out a/f?

invest in a safc and lean out your mixes :P

I'm getting about 330 till the fuel lights come on.

I think I average about 100km for every line. 3/4 tank = done 100km.. roughly..

would LOVE to learn how make my car go further every tank..

cheers

Exactly the same.

I seem to get close to 100km per line, then it just drops bad when it goes past half way haha.

R33GTST - I average 500kms per 45-50L - 70%-80% is freeway driving though .....

yeah i do about 5% freeway/motorway driving... depends where i go on the weekend... even then, im probably in a rush and still boosting it :P

my fuel economy is about right... probably a little better then normal... im not very conservative with fuel, yet it goes pretty far :D

    • Exhaust end of this month, and then tune after that whenever there is availability. Still tossing up between a pure 98 tune or a flex 98/e85 combo.  The (lack of) milage in e85 isnt great. Start to get anxiety if i go for a long drive and there arent any united servo's nearby
    • I mean I can be OCD'y but this is really over the top. At that point why not just run a full wideband fuel controller? Especially if you run 3 widebands. The system works pretty well, which is trimming low load stuff to be within a few percent of the base map. Pre-engine _change_ the base map was only 1-2% off, depending on ambient temp, elevation, etc. Under load the LS is really very straightforward to tune, enough that a wideband closed loop would be overkill. If I really cared (and I hope I don't) I can always just go back to the MAF system the car actually came with. Which does all those nice calculations for me (temp, altitude, etc), now that you can buy 102mm MAF's that do not cause restrictions.
    • Good afternoon Team , just a quick update on performance mods  Current Mods list (Installed) HKS - Power Editor (Came with the car) looks to be some kind of boost controller RV37 Skyline 400R (SKYLINE) | FUJITSUBO  - Cat Back  RV37 Skyline 400R (SKYLINE) | FUJITSUBO  - Front Pipe AMS  - INFINITI Q50/Q60 RED ALPHA COLD AIR INTAKE KIT AMS  - Performance Heat Exchanger Intercooler Not Yet AMS Alpha Performance Full Race Down Pipes  - to be installed in May 
    • I'd be installing 2x widebands and using the NB simulation outputs to the ECU.
    • Nah, it's different across different engines and as the years went on. R32 era RB20, and hence also RB26, the TPS SWITCH is the idle command. The variable resistor is only for the TCU, as you say. On R33 era RB25 and onwards (but probably not RB26, as they still used the same basic ECU from the R32 era), the idle command is a voltage output of close to 0.45V from the variable resistor.
