Bad Fuel Economy And Idle Probablm

[r32u]

Hey put a rb20 turbo setup on my rb25 and got gtr injectors and dyno tuned.

Made 150kw but was missing got new plugs and drives mint.

But when it idles it is either at 1100 or 2000.

It also uses so much fuel $25 gets me 40km and it seems to be getting less.

I've taken apart the aac valve and cleaned that but it makes it better for a little while.

Cleaned afm and have wasted spark setup.

Any ideas

What management?

[siddr20]

uh? so you have a r32 with rb25 motor?

You got correct ecu in there? If so which one?

For better fuel economy change 02 sensors, put the correct heat range plugs, and clean your afm.

But if you saying that you only get 40kms out of 25bucks, then you got a serious problem.

You sure theres no leak in the fuel tank?

Coz 25bucks worth of fuel and you get 40kms is BADDDDDDDDDDDD

OR could it be that your dash speedo thingy is broken?

its got chipped ecu and 10litres gets me round 40km took out sensor and had a build up of crap in the holes. will get a new one soon but dont know if it would cause that much trouble

replace the 02 sensor - you can't clean it

its a cheap part and its soley responsibility along with the ecu is to save fuel
