Fuel Economy

[Adam.Findlay]

plus if you get a wideband and adjusting the narrowband enulation does not do the job you can always adjust the MAF screw to lean it out. I did that, and when I finally got access to an openport 2.0 cable to reflash the fuel maps I didnt have to change bugger all of the fuel map because the MAF screw mod had got the AFR's almost bang on. made it drink a bit less gas.

but seriously guys you must have heavy feet. I have a bloody heavy foot I must admit and I still can get ~450 to a tank without having to be too careful.

i somehow managed to get an average of 9.5km/L, filled it up in tauranga, headed to auckland, over 200k trip, cant remember now, then did some driving around, did a total of 453k before filling up to come home, i tried to be light on the throttle on the way up and around town, clearly made a difference, would have wasted that entire fuel saving coming back though haha

I use more fuel than what I did when the car was an auto hahaha.

So messed up. I don't really give it sh*t much anymore, I still need to change my plugs and do a boost leak test. Hard when working cause I cant be f**king bothered to do anything during the weekend haha.

PLus can't really do anything this weekend as working doing the V 4s and Rotary show

I have try to be light on the throttle and stay off boost as much as I can, Can get around 350-360kms tank this this around town, Get around 150kms from the first 1/4 of the tank but next 3/4 of the tank seem to go down really fast and doesn't seem to matter how your drive it.

I know my plug ect ect need doing.

Ordered some spark plugs through work, less than $15 each

So whenever I change I shall see how much this helps

that sounds awfully cheap, cost me about $20 + gst recently for irdium long life ones from BNT

[low_vr4]

Yeah I have no idea, fuel economy is better since I replaced the fuel filter hahahaha



Nope its a recirc one, looks like a knock off GFB one.

I need new plugs but I cant find anywhere that sells BKR7IEX, was going to replace the O2 sensor when I get an AFR gauge and sensor. Def need a tune/remap but pretty sure theres no one up here that could do it, still have a few things to put on the car like fpr, large bore fuel rail adaptor, walbro fuel pump, ebc

Maybe get a decent recirc bov? There is a guy on ozvr4 forums who sells evo 8 mr metal bov's for $150 aus. They are awesome.

Could be possible that it may be failing but I dunno, car has only been drinking fuel like there is no tomorrow since I've been using the sh*tty 95 fuel

Damm, bugger, poo!
Plugs, check! Fuel filter, oxygen sensor check! Oh its pissing me off, down to 250 kms per tank! Not enjoying the drive now, no WOT, no boost...life as I know it is ending!

Wow thats worse than what I get haha

My fuel economy is worst now since doing the plugs, new fuel filter, new k&n panel filter along with injector cleaner now doing around 320kms to a tank, Know my blow of valve leaks abit but finally found a EVO 8 blow of valve and taking it in for dyno check next Tuesday and see if that found anything wrong.

Check the coil packs aren't sparking out. That makes a huge difference, along with leak testing the pipework.

Wah, you hates me!!!

Is there some visual indication of "sparking out", haven't heard of this term before. Will double check the pipes but not holding much hope there.

[wintertidenz]

Spray them with a squirty bottle while the car is idling. You will hear/see it.

[babasvr4]

Ok right, bridging to earth/ground...Cheers for that!

[Sikvtr]

I got a fuel tracker app on phone an im getting bout 14l per 100k. pretty ****e really, is fairly standard an is triptronic
gunna get trans flushed as that may help a little and check over it all when cambelt is done. maybe aftermarket ecu with tune?
sad when my wrx running 16psi with external etc was getting better economy lol so much for subys bein the most expensive in gas

[Ryan]

9.7L / 100km (combined cycle) is my best so far.

[babasvr4]

Well my best ever fuel usage is now 13.3 litres per 100km! Sure it's not famous but a long way down from
a high of 20 and average of 16.
The only attributable change is a new EVO metal BOV, I doubt the new intercooler would help.
Must have been suffering boost leak.

thanks for making my 13b look cheap
