hey muz have you been to the dyno tuner just off anderson street dyno dynamics it's near ray hall?

are you the one that tried to drag my wife off in a silver r33 if so your car definatly needs a tune

Thanks mate, I take it you are referring to Cairns Dyno Tune. He knows even less about PFC's than SVS unfortunately.

No sorry I'm not into street drags and the only Silver R33 I know of and have seen belongs to bloke. Always willing to chat though. Also AKAIK, mine is the only black R34 in town but if there is another one, I would like to meet him and compare notes.

Cheers

Don't qoute on me that. I've the same situation as yours b4, however after i installed the Earth ground kit and reset the ECU. Now i could get about 380-400kms per tank city driving. i think u should try to reset ur ECU first, to see how is it goes!

Hope this help

I've always had excellent fuel consumption from my GTS-T and boost hasn't appeard to make any difference.

On the dyno I was watching the AFR's under general moderate acceleration and noticed they are always hanging around the mid 13:1, under light throttle it would almost immediately flick to 14.6-14.7:1.

The car did feel a little lazy with the transition on to boost (when boost was ramping up) but once it hit the AFR's would go rich and it would pull nicely.

From what I've seen tuners tend to try and get the AFR's around the 12:1 some times a little richer in the boost transition period.

This boost transition period is where the general driving hang around.

Lean this area out under moderate acceleration and you should pick up fuel economy but loose a little punch.

I wouldn't think the punch under light throttle would matter much as if you want the punch you put your foot down boost comes on and down goes the AFR.

Due to the crappy timing light it was returning just under 400km's a tank.

Timing is now up from 5degree's and back at the std 15degree's.

I've been watching the RB30DET on the stock RB20DET ecu and is now returning no less than 430km's per tank with a heavy foot and city driving.

Occasionally nudging 500km's a tank depending on how hard I accelerate when I first click the gear.

Thats some impressive fuel economy Narlzz. :rofl:

Nudging in to the mid 9L/100km's. :P

      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.
