u could just tell us what causes bad fuel economy

I have two thoughts now, if your afrs are near on that 12.

The 12s are on WOT tune, so everything in between that and idol sucks ducks nuts. meaning drinking fuel as you dont drive round with your foot flat all the time.

2nd thing could be a fuel leak still, which would mean it could still be tuned properly. Just the fuel isnt all making it to the engine.

yer, it doesnt seem to matter whether i boost it or not, my economy is still bad

which leads me to think its something else

i would hope that the tune was done propperly, coz it cost a f**king fortune, surely i shouldnt have to tell my tuner to tune not just for WOT but for normal driving as well????

the economy was bad with the stock ecu anyway, so im pretty sure that the tune, while it may not be helping, isnt the issue

there is always a strong fuel smell when i reverse, but i can never smell fuel in the boot area after running the car

im interested in the evaporation issue the aussie fuel filler/nossle issue that was bought up before, and i pm'd the guy from nissan silvia who fixed his economy by replacing his charcoal cannister (he reckons he did nothing else) so, im going to hook mine up again also

my o2 sensor is brand new

ive had a heap of fuel hoses replaced as it was discovered that they were perishing (along with every other hose in my engine bay that ive had replaced)

this problem just seems to common, so many of us suffer from such bad economy

i want to know what causes it and how to fix it

spook i have no canister and i can get a bit over 400km with normal driving (which includes a bit of boost)

i got 350km last tank and that included a whole lot of boosting over glorious

can you pull up o2 sensor readings on your pfc? have you cleaned your afm recenty?

yer, ive been watching the o2 sensor readings on the hc

seems to be working correctly

i havent cleaned my afm

woudl it being dirty affect its readings?

ill check and see what sort of voltages its reading;

Maybe get a PFC retune?? My new car has a PFC and I get awesome ecconomy (411ks out of 35 L ;) ) The new car gets no fuel smell at all where as the R33 you could smell it all the time (Stock ECU) I think engine managment would be the main factor that effects fuel ecconomy

damn, some of these posts are crazy, the other day i got 350km with 36litres, and i have a stock ecu, with other mods, i have a power fc waiting to go in, these posts are sorta scaring me puting it in and tuning it :)

Spooks,

Go back to MM and get them to look at it firstly. I think that you should give them an opportunity to explain.

On a side note I had my PFC tuned there and am quite happy with the fuel economy, granted I mainly drive it on weekends and it is warmed up before every drive and then cooled down...

yer, im not convinced its the tune

fuel economy was bad before the pfc (350ks to a tank, with just exhaust, dump pipe, fmic and plenum)

im going to get my mechanic to check a few things out for me next service and see what he comes up with

then im going to get in touch with elite and see what he says

    • How much have you lowered?  I had 350Z springs in the rear and was able to pull the camber into factory spec with the factory arms on the rear, obviously the front ran negative camber as it isn't adjustable, but rotating the wheels regularly evened out the wear.
    • Either the installer needs to come back, you need an auto electrician, or you need to learn automotive electricals yourself.   First step Id look at is where that big thing came out of, is there still things unplugged at that location? Maybe they just forgot to put a relay in or something?
    • Well, this is probably where a wiring diagram and a multimeter come into play.
    • I can say to anyone thats doing this; having done a number of R clusters; just be careful if its an unknown cluster.  It takes a bit of force to pull up; but if it feels excessive then its probably stuck. I've had this and pulled the entire hair spring out; and I can tell you; its not easy getting the correct spring replacement with the correct inner diameter and winding. In my case someone had used some sort of adhesive to stick it to the spindle and it pulled the whole spindle out; which the force seperated the hairspring from the spindal and caused it to deform.  You may have to clean it (IPA); or in my case if i'd known i should have used some sort of solvent on it.  Also check out Cruizin Central on eBay. He does all sorts of dials; and you can email him with any custom designs you want. So if you want like certain logos etc...he'll send you a mock of what it will look like then you accept the order and he'll take care of the rest. Fantastic dials and he can do basically any design you want. 
    • Have you confirmed its the actual axles? Also the wheel bearings that mount on the hubs to hold the axles wear out. I replaced mine as they got play in them. It sorted my play issue.
