Whats actually involved in tuning the car to get better fuel economy?? Can i do this myself??

Car was well tuned from the dealer and I was getting about 450K's without thrashing it from a full tank of 98octane. Seems about the norm. (unless u have a GTR)

tuned from the dealer?

how can they do that with a 'stock' ECU ?

It just had a very comprehensive service from a place we both agreed on before I took delivery.

Ash your mind is so corrupt with *mods* that you forget what tuned means [service / tune].

btw my kms are with BP Ultimate 98 too.

i think they can, they have machines that plug the ECUs into and gives them the maps etc, my mates piece of shit mobile was ****ing around, injectors flooding etc and hyundai put his ecu in their comp and fixed it up!

yer, but that is a Hyundai. Any car these days basically has that functionality - and its pretty common for locally sold cars to have the whole "jack in" mentality.

You can muck around with the Nissan CONSULT tool, which will plug directly into the ECU and you can fiddle - but that is mainly a diagnosis and troubleshooting tool, not a tuning tool as far as I can gather. Read the 200sx or the R32GTR service manuals (out there as PDFs) and you'll see what it does.

New plugs, new belts, new fuel filter, new oil and oil filter, radiator flush, gearbox and diff oil change, power steering fluid change, battery fluid check, air filter check, brake bleed and adjust, tyre rotate and balance.. ...all helps !

Average about 400-450km from mine.

The best I had was driving to Yarrawonga and got 560ish.

Worst is when givin it a good thrashing. I can expect about 350km... but more fun

[Al]

I get about 340. That's from full to 1/4, i never let the fuel go under the 1/4 mark.

That's with my existing mod's.

[Jetdat]

i get about 450k with some stick, driving off boost about 550k.

on the other hand if i give it a lot of stick about 350k.

[DJ_L3ThAL]

jesus, i wonder why i get so little??

[Jetdat]

DJ oxygen sensors if not functioning properly can cause excessive fuel consumption..

i am not jesus but just a thought

[DJ_L3ThAL]

would and oxygen sensor cause any other type of noticeable problems that can be found on a dyno ? as ive had a full powerfc dyno tune and everything looked fine on there, hmm, gotta get a retune next week anyways so i will tell them how much economy im getting and see what they say

[Jetdat]

a faulty oxygen sensor will be noticed on the dyno, but as you mentioned powerfc may be the cause of your fuel consumption, and i am sure can be rectified on a dyno....

[Sideways]

Costs me about $20 for every 100km's I do... (32GTR)

I only usually stick in $50 lots and always get around the 250km mark... doesn't seem to matter how I drive...

Compaired to my old carby turbo 240Z at around $20 for evey 50km's... it's a dream

[NismoR34]

Just got 455kms out of pretty much a full tank - however consider this: I drove to heathcote and back, I also had 17 drag races at heathcote and also did lots and lots of fanging during the week, plus some normal type driving - I would say that my air / fuel ratio's and general state of tune is pretty darn good

I am now wondering how Jamezilla fared from doing the same thing ? Did you go through 2 tanks or 3 ?

[Jamezilla]

Haha

2 tanks Damm that O2 sensor.

Must get fixed...

[riggaP]

480 out of that last tank..... including about 4 miles at heathcote consuming a full 1/4!

[Guest Robo's]

My first full tank just done, 414 ks, or 8kml, or 12.5k/100 or 22.6 mpg

Plenty of foot flats in that too.
