Are buddy club spec 3 cams too BIG for reasonable fuel economy?

oh wow that is crap consumption

see how it goes after the tune man, maybe the itb's really chomp down the fuel?
i'm just using the stock dc2r im and a larger throttle body

changed the fuel filter lately?

ITB's can make your fuel consumption suck ass if the tuning is no good, especially on the B-series cause it has no wide band correction.

I use to normally get around 350km's a tank city driving (B18CR ITB's, 4.9FD).

Now with my K I get 500km's+

Anyone with a ITB'd K to compare?

Barefoot, would it help with the ITBs on the B-series to have closed-loop lambda control, as available with MoTeC M400?

I'll have to stop 4 times on the way to sydney for fuel. I'll also go deaf at 100km/h at 4200rpm...

If Motic M400 requires a wide band o2, then i'd say yes it'd help. But as it is, you should get at least another 100km's a tank if you got a decent tune.

It will be worth your trip.

**vinnY** · 26-03-2009 11:32 AM

i don't see why not?
