have you tested your o2's? you can do it using a voltmeter or using consult/datascan. you just need to make sure they're nice and responsive and that the voltage output should sweep from low to high about once a second. datascan or consult is easiest coz it will just display the voltage output for you. just make sure your car is at operating temp and you'll need to rev to about 2000rpm when you're measuring the voltages.

yea freind of mine hsa consult but he is currently at albury he should be back in bout 2 weeks il run the car thorugh that then. but it seems to be ok now, have to wait and run a full tank first to see.

he also has a NA zed :P

There's only one O2 sensor (in the extractors), the one down near the cat is an exhaust temp sensor.

check out Kudos in the trader section for good cheap O2 sensors

I do not believe the sensor near the cat relates to how much fuel you use, I run my car without this sensor and it has no issues.

I also believe its a temperature sensor, not an O2 sensor....

im confused, how come it seems like the more i put my foot down, the better fuel econ it is??

the for past month, i been driving like a grandma and my car drank 10.8 - 11.2L/100km

but last week, i was having some fun in the car, and the car only needed 10.2L/100km.

can any1 tell me why?... and is it true that it saves petrol if you change gear at about 2000 revs?

too many variables for such a small difference.

are you measuring ambient temperatures while you're doing this?

the quality of the fuel?

how did you calculate the fuel usage?

for the whole time, i been putting in V Power.

i calculated by L of petrol divide by mileage, thats right...isnt it?...

The draft Fuel Consumption Information Rule proposes that importers of light vehicles provide accurate and reliable fuel consumption information and seeks to clarify how this information is collected.

      Wife wanted basket things in the wardrobe in our temporary house. Thought about ripping our the wardrobe and fitting the entire IKEA set, but it's a temporary house and we want to move in a few years. So IKEA advertises this as a 50cm unit, however the actually basket and rails measure 46cm wide. Only issue was depth, IKEA stuff is quite deep, where as the builder special junk is super shallow at less than 40cm. Send it, chopped the rails, then offset the mounting holes, job done, happy wife, less shit scattered all over the bedroom. Did the same to the other side too. Also drove the Skyline shit box today, dropped off oil at Supercheap Auto. I didn't realise they only now take max 2x bottles per visit. I visited 2x Supercheap Autos.

      Strange issue RB25DET wont start

      I've seen similar actually in my situation. You never know what tables are attempted to be used when the car thinks it's -99C or +200C. The fail state is not usually that extreme but you know what I mean - it was in my case though! This is where being able to read all the sensors is useful cause you see this stuff really quickly.

      The above is very important. However as long as you keep timing relatively low, it's plausible to make your own knock ears and plausible to learn to tune with a modern ECU that can do wideband O2 correction like a boost controller. I mean if you only have one viable road to even drive the car on, learning to tinker to this level may be worth doing given you can't do much else with the car...?

      I find the fact that the rear plate has to be bent inwards at the rear not so bad: but the front is just awful: It's like come on. (these are my very old, now retired/turned in plates) TBH it is a lot of money to fix a minor issue, the fact I said "I'll never really spend the money on doing this" is why people ended up buying them as a gift for a 'car guy' who can be hard to shop for.. for car guy things.

      I just bent the ends of my premo plates. It even went through Regency like that after the engine conversion and the inspector (a great bloke!) just squinted his eyes and said "I didn't see that". Plates, and how they look, are just something that have zero importance to me.
