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 . .. .

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

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...

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

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.

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..

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

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 :D ) 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

what power you making bunta?

retune :D

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

    • Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.  
    • Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it  
    • Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground
    • I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.
    • Is it alright to top up with just another green coolant?
