Something is not right there then

Where are you located? Someone knowledgeable should be able to help you out

I'm getting bout 270km max TAS roads so short trips got nistune, cooler, walbro pump, splitfire coils no exhaust... 194kw@ the rears. Is that normal??

Nope, I used to do pizza deliveries in mine, in tas

I used to average 12-13l/100km

[johnnysr22]

Ok... Well when I got the car it was stock as a rock! And I think it was doing about 170km! So it would be a good idea to get new o2 senser...

[juzzy.melb]

Changed o2 and cleaned AFM. Nothing still 17l per 100. Reset ecu. Mm could not notice any change but on the same tank of fuel disconnected boost gauge and teed in greedy boost controller of previous owner. That was taking vacuum from hose between plenum and fuel regulator. Connected boost sensor of hks evc to this line. Now all of a sudden fuel consumption drops to 14l. But had done some long freeway runs on that tank too. Will see on next tank fill. So I dont know if it was ecu reset or the mucking around with hose connections to the fuel regulator. Could long hoses teed off there be causing the fuel regulator to be increasing fuel use?

Fuel reg line might well have been the issue.

Ok soo went for a long drive this week and managed to get 450km out of that tank, best soo far

[pipster11]

thats getting better

what boost and state of tune is it again?

[GTR260]

14psi 370hp atw,

[pipster11]

pfc or nistune?

either way, sounds like not much work was done on lower end of the tune

also, o2 sensor feedback could be turned off

[GTR260]

Haltech platinum pro, o2 feedback is on , tune is fairly fat with no timing.

[pipster11]

450 is not bad for that power

but it could be worth asking your tuner if he could lean it out on the cruise parts of the map

i get around 500kms from a tank not on the highway with the stock tune which is super rich

[4bidn1]

Im getting about 270 to 300ks a tank full of city/ hills driving on e85 and my stocky does between 380 450 on pump.

[STAG123]

Thats not too bad my stock 2002 m35 is only just getting 500 to the fuel light that's driving like a granny 60% city 40% highway...??? Its just wound over 50,000 Kim's on the clock. Is this normal for a M35?

They seem to do that a couple of times in their life.

I would be replacing the o2 sensor, cleaning the AFM and changing the spark plugs if you are worried about fuel economy.
