Only way I know of is to buy a OBDII reader. You can get bluetooth readers off of eBay for $25 or so and pair it with a smartphone. Most smartphones have apps available that can parse that data. For Android, search the market for Torque. It'll give you a ton of information to play with.

I have pretty much come to the conclusion that i need 37's and that will bring my rpms down and it will still be great on highway and off road

I realize that I could probably get this info with something aftermarket. My question is why is there even a reset all option? What else is reset when you hold the arrow on this screen? I've tried holding different buttons to see if it cycles through other options, but no luck.

You can kinda mimic realtime mpg with the stock computer. Just reset it about every 10-20 seconds, and it will essentially be averaging on a 3-5 second interval. You probably aren't exercising the accelerator more than once every 3-5 seconds, so it should give an pretty accurate assessment.

You are correct, the Aeroforce Intercepter guage does show that parameter in real time. I use it occasionally, but it gets annoying to look at it because it fluctuates an insane amount. Any tiny amount of grade change, any headwind, pedal input, etc. has huge effect on the mpg's reading since it measures down to one or two decimal places, and it gets nauseating to look at.
After seeing it read 3 mpg enough times when I am accelerating, I no longer wanted to know anyway.
