r33 fuel consumption?

[igor]

Just looking at my last receipt - 419km from 52L BP Ultimate. Stock except for bleed valve @ 9 psi.

[-= SKiZO =-]

I get about 360km per 55l - city driving - BP Ult. :ddd:

Ok fine, that's pretty much the same for everyone on stock. What about you guys with changed ECU's? Is there a significant difference?

...Trying to justify forking out some cash on an Aftermarket ECU.

Some of you guys are getting some pretty good fuel consumpution, on a trip I am lucky to get 350 to 400, the thing is always on boost just a slight tap of the gas peddel and straight on to boost. I only have slight mods. exst, fmic, re mapped comp, airfilter, bleed valve. 10 to 12 psi

Makes me glad my stock 32 GTR doesn't boost until 3500rpm.

More boost = less petrol

350km's or so per tank is to much fuel consumption.

Check your O2 Sensors ppls.

My Rb30DET with the stock turbo is able to make 11psi by just under 2000rpm. Simply letting the clutch out you can hear the turbo whistling away.

I get 430km's per tank with it poping and farting on light throttle so it is still running a little richish under certian conditions.

On cruise & idle (on the dyno) the AFR's are a perfect solid 14.7:1.

It doesn't sway, perfectly dead on 14.7:1.

The R32's turbo's from factory are supposed to get 10.5L/100km's.

The R33's turbo's are supposed to be slightly better with 10L/100km's.

This is obviously when they are bran spankin new. When the injectors become clagged & o2 sensor buggers its self obviously fuel consumption is going to go through the roof.

Cool, I'm pretty much on par.

I have changed the O2 sensor recently, havent noticed much difference, will make up an excel sheet and see whats happening. Need to clean the injectors though, the throttle is a bit laggy and i m still not happy with consumption.
