I would love to see this feature in Centrafuse. You could add in a formula that calculates the Miles per Gallon and display it in the OBD-II (OBD2) screen. Two of them, one reatime/current MPG and another long term MPG with a "reset" button like an odometer. Much like a Prius has in their touchscreen interface, but way cooler cuz we are talking about the best front end; CENTRAFUSE!
