Charcol Cannister

[Spook's_Skyline]

can it affect fuel economy?

i noticed in another thread that a guy got an extra 50/100 ks to a tank of fuel by replacing his charcol cannister

my fuel economy is attrocious and i know my charcol cannister isnt hooked up . .. .

[Mud]

WTF?

[Spook's_Skyline]

was reading on another forum that

before i was gettin like 300, until i replaced the charcole canister.. seems to better now..

ive replaced my o2 sensor and fuel economy hasnt changed from 300ks a tank (regardless of how i drive, regardless of low or high boost)

gets slightly better with highway driving

Dude, maybe you have a shot ecu hey... Maybe see if someone else can lend you theirs, or something. That or MAYBE your speedo is way out???

[Spook's_Skyline]

got a powerfc

fuel economy was bad with standard cpu before

still bad with powerfc

[dangerous_daveo]

Is the speedo correct? As Im guessing thats the only way you can tell your kms. That or you might have a fuel leak... Maybe. Done all the injector cleaning etc?

[edit]

I dont think a charcoal canister will affect things that much either. I mean mine isnt hooked up, yet Im on 535kms and my fuel light isnt on yet...

no one has answered the question yet...what does the charcoal canister do? Mine was unpluged too but I plugged it back on...didn't make any difference with or without....anyone???

[Spook's_Skyline]

yer, speedo is correct, havent done injector clean, but will do

was really hoping the o2 sensor woudl fix economy, but its made no difference at all

strong fuel smell reversing the car up the driveway, and apparently it did have a fuel leak, but piping was repaired

cant smell fuel in the boot at all though

[dangerous_daveo]

Could be somelike like an injector seal? Who knows dude.

But a charcoal canister has to do with the emmissions control. It is illegal to have it disconnected. Has something to do with fuel vapour or something from memory. Dont quote me on that tho.

removing the charcoal canister won't change fuel consumption

all it does is stop fuel vapours being vented to the atmosphere without going through the engine

they are feed back into the engine on cruise

Could it be the pfc tune?

[Spook's_Skyline]

Could it be the pfc tune?

<{POST_SNAPBACK}>

im sure its not helping, but no, the fuel economy was pretty bad b4 the tune even (350 KS TO A TANk)

[nF]

could be the 2 extra doors i guess

[dangerous_daveo]

Is it auto or manual?

I have the same problem with my GTT...went at most 360km full tank...haven't done anything..but I'm going for the power Fc approach..

I'll be tuning my car on the 21st...will prolly know the difference with the fuel consumption a week after..I'll keep update..

manual

My car uses a hell of a lot of fuel compaired to other cars as well. I normally get between 300/350 city driving and 400 highway.

Even when we drove to cairns, the car still only got 400km per tank. Yes admittedly there were places where we weren't doing the speed limit... but I still would have thought that it would have got more than 400k per tank :S

[Spook's_Skyline]

yup, that sounds about the same as mine

i dont get why we are getting such bad economy, yet other skylines making more power in some cases, get much better economy

the bloody car costs me enough as it is, just keeping it on the road, would be nice to get a petrol break, and squeeze an extra 100ks out of the tank

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

[Spook's_Skyline]

what power you making bunta?

retune

wifey wont like it;

ive already spent hundreds of dollars on tunes (switched exhaust, retune was another 300 on top of the origianl 600)

surely for that amount of money, it wouldnt just be a power tune

was done at mercury
