My last tank was 145miles .. and that was just commuting to/from work.

I can honestly say that by the time I filled up yesterday it was the first time I had seen 200 miles from a tank.

I get 180 to 210 mostly.

Mainly due to commuting.

If I do long journeys I average 250 per tank, as I usually cruise at 90mph.

320 miles isn't too hard as long as you're careful with your right foot.

Got less than 10 mpg yesterday 85 miles for 40 litres.

It is, but excessive fuelling tends to be the fault of the lambda sensor (used to govern fuelling when idling / cruising)

Cheers MB...would i be correct in thinking the Map sensor is more for general running of the car...smoothness etc

The job of the map is basically to determine eninge load. When you have your foot down or on VTEC, the lambda is ignored and the map sensor alone is used for fuelling. It sends a constant but varying voltage(which correlates to a manifold pressure) to the ECU, then the ECU has inbuilt lookup fuelling tables to decide what amount of fuel to put in. The ECU also looks at air temp / coolant temp / knock etc to determin correction values to help get it spot on.

But yes, the map is used all the time, just the lambda is used in a feedback loop when you aren't driving hard.

Approximately 280 per tank at the moment but then i'm still banned from V-teching!

I did 280 miles in the fast group on SM4 (and yes, I wasn't left behind ).

200 on a good day
That's what bolting on hair dryers do for you.
