11000 miles stock tires, 11.3mpg overall. At about 10000 miles I added Bassani cat-back and Airaid intake. Since then I've averaged 12mpg with city and highway driving. Next week I'm having Bassani install new long tube tuned ceramic headers.

I get 10.4mpg with a heavy foot (I just can't stand to be behind some folks ) at about 18K miles.

The computer knows when the tech resets for an oil change, also when you get gas it resets your max trip length and I'm sure a lot more. But does anyone know when the Average Econ is triped or is it based on total millage or recalulated on some unknown numbers of miles.

YOu can manually reset it by paging to that display then holding down the return button. as far as I can tell it does a running average e.g. it calculated the average based on a certian number of data points (mostlikely limited by memory in the computer) and averages in the new data as it is recieved.
For example it might use a 16 point running average where it sums the mileage for the 16 points including the new data then divides by 16. that number could be 16000 for that matter. thats why you will see the average change rapidly immediately after resetting it and it will slow its change after it has been collecting data for a longer period of time.
The data point are based on fuel flow and distance driven. both which are measured by the computer and used for many of the functions that you have on the rig. in the olden days the instantaineous mileage was based on engine vacuum once teh sensor was calibrated to the vehicle.

soooooooooo.........what your saying is it starts over everytime you reset it.

I did manuel test yesterday, it came out better then the onboard comp. I figured it as 13.11 mpg. thats pretty good for all around use I guess.

12,000 miles, stock tires = 12.5 (all highway)
37 SSR's 11.4 (speedo not calibrated yet)
