Just wondering what MPG do you get as i got 280 out of a full tank, when i drove to Skegness. Thought that was a bit low but not too sure? So this was all motorway driving...

Although only an S16, I get 27.8 MPG (10.1 L/100 km)
This is the average of over 20k kms.

Might be worth doing an ECU Reset so that it's not using the old sensor readings.

oh come on who expects decent MPG on a 250bhp car, as I may have mentioned in the past these aren't for people with shallow pockets

I measure mine by the light. Though you then technically have to be on level ground. I reset my trip as soon as the light goes on every time. Then go fill up with

If you're car has been custom mapped i.e, for the supercharged boys, wouldn't an ecu reset lose the map?

THE ECU RESET IS THE BIGGEST MYTH EVER!!

But no, the ECU stores the engine running data in an EPROM, which does not lose its memory when it's disconnected from the power source.

No, it won't make any difference.

The most likely culprit for the poor fuel economy is an ineffective lambda sensor, do you know if this is working, if it's been changed ever?

It may be worth getting it plugged in, to see if there are any other sensor related issues.

What fuel are you using? You will get the best economy on Shell V Power.

It's 'cos your using the wrong injectors.

No one else get's anywhere near that low - not even me with 400 + BHP.

Whatever your using must have a higher dynamic flow rate than the Bosch 020 150 558's that we use / recommend - even if they have the same static flow rate.

I'm 99% sure changing them will solve your rich running.
