Need help! (service, fuel problems)

[Informer]

Well, I've just calculated that I'm getting about 250km on a full tank on my R32 GTR. Most of the driving is during traffic and below 100kmh (never been on a highway yet).

Is something wrong? I'm not pushing it hard, driving it leisurely. I have a feeling that its running rich or something needs replacing.

So, if I take it for service how do I ask to get it checked for this problem? i.e. My car is running a bit rich, how do I make it run a little more efficiently because I don't need the extra power or early boost for daily driving. Could someone guild me to how to ask this in Japanese? Thanks!

Ask someone to go along with you to explain? Easier than us telling you a few sentences which may not answer the mechanics questions.

Else just get it tuned with a new ECU now since your thinking of going for more power in the future anyway.

Informer: check the ECU... you might be running a re-programmed one.

as a baseline figure, the city cycle for an unmodified r32 GTR should be around the 4.7km/l mark (according to driver magazine)*

* FD of the same era, according to driver, is around 5.6km/l - for those who are always pick on our fuel economy

Well, I've just calculated that I'm getting about 250km on a full tank on my R32 GTR.  Most of the driving is during traffic and below 100kmh (never been on a highway yet).  

Mate 250km on a full tank!...as Rezz suggested I'd check the CPU.

As 250km is as bad as mine on city driving and I've only got a 50L tank compared to 72L in a BNR32.

As a reference 10-15mode is 7.0km/L and 8.2km/L (after '93 model).

what year is the GTR? could be an old faulty o2 sensor

[Informer]

Hey thanks people.

My car's a late 91.

I can smell petrol in the cabin when I drive so something's going on there.

So I have to check the following :

- ECU (would I need to reflash this regardless of whether its stock or not?)

- O2 sensor

Thanks again.

[drunkenmaster]

If its stock then you wouldnt need to reflash it as nothing would be wrong with it?

not wishing to state the obvious, but are you sure there isn't a leak in the fuel lines or fuel tank....?
