hey guys

ive had really bad fuel milage (approx 280kms a tank)

anywho i was thinking it was the o2 sensor, but when driving home from work i watched the stock boost guage closely.

at normal cruising, it sits close to -6 but once a bit of throttle is put on (below 2.3-3000 revs) it moves up to 1/4 mark and somtimes 0.

am i getting constant boost? i know a turbo works on exhaust gases but i dont know much about the factory boost guage.

your only getting boost when the gauge starts going above 0 into the positive area, sounds normal to me.

try new plugs, fuel filter, clean out you throttle and AFM and swap your O2 sensor, should get you out of trouble

yeah it is, running stock boost too i think so 5psi or whatever it is.

just wanna know why i got such bad fuel consumption, i know skylines are a performance car but 280kms out of a full tank still?

and thats not floggin it every time either

^ exactly - the list is long.

The answers are plenty however - please do a search.

Its been covered pretty well as you could probably imagine... being fuel economy is a reasonably big problem for most people

sounds like the turbo is spooling up but, even when under the 0 in the negative side

yeah my car does the same thing, but its just the pod filter sucking air in, you can tell the difference between the induction and ur actual turbo spooling

Do all your regular maintenance as per the many threads covering this article, don't bother trying to work anything out until it's fully serviced then go from there.

An important thing to note is cold and hot starts as was mentioned above. All cars use more fuel when running cold so if you;re ot trips your fuel economy will suffer badly.

Get used to high fuel consumption. 280km is low for sure but your never going to get fantastic results. I went from a 3L v6 magna to the skyline and the magna despite being 500cc more drank SO much less fuel.

Also given that you have had the car for such a short period of time, is it possible that you have just been enjoying it quite a bit, ie giving it a bit more throttle than normal, going for short cruises around the block etc? When I first got mine the whole turbo thing was awesome fun but led to driving in a way that was very harmfull to the consumption.

as mentioned before ^^^

just give your car a decent service, change all the fluids, spark plugs, give the afm a decent clean....warm it up and then go for a nice drive....dont thrash it just drive it normally and let things smooth out.....you might notice a bit of a difference in consumption....

    • Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).
    • Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers    
    • Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.
    • Pull codes via the self-diagnosis procedure. As far as I can tell this is just a sign of transmission issues but not a code unto itself.
    • Hi All, putting the engine back together and everything is perfect except have this plug left over.. any ideas what it is for and where it goes? Is on cold side under the intake plenum *note not a stock plug, as everything has been modified Cheers
