I have been reading the posts on the Mugen ECU giving better than stock gas mileage.

I have been monitoring my gas mileage for the past 600 miles (including the Ashville run) and I am getting 24.1 mpg average. I was surprised that it was that high considering the hard accelerations at S2KDays.

What is everybody else getting?

 

My S is very consistent. The gas tank lights come on right at around 250 miles range. The first few bars on the gas guage disappers rapidly but the middle bars seem to last quite long. But right at around 250 miles, it will be down to one or no bars left. Everything all stock.

 

My car averages about 24 mpg during the 23k miles of ownership. At one point on the trip back to Houston, I actually got 29mpg!

 

I'm getting about 23...

 

Less than 400 miles on her, and she's getting 28mpg(of course I'm baby'in her during her break in period)...

 

I'm getting 210 miles per tank or 21 mpg city driving.

 

Track ~8-10 mpg
City ~ 16-19 mpg
Highway ~22-30 mpg

Average about 20 mpg.

 

I get an average of 23.5126 after 62 fuelings.

 

Could you please post an exact figure instead of just average.
