Fuel consumption display

Guys, I'm no authority on this, but if that data is available on the OBD2 connector in your vehicle, how about just getting a bluetooth OBD2 adapter, and couple it with a tablet/phone running Android (App: Torque)? Would be an inexpensive, and easy solution.

Thanx.

BUt what I need is an approximation. I understand that there is no way to caclulate the fuel consumption because of the acceleration, deceleration, and load. However, if you are calculating fuel consumption at a constant speed, then wouldnt there be an equation to calculate the fuel consumption.
