Lets back up. Why are we doing this, aside from we want to learn how to do this? What is our mission?

From my own perspective:
Misson: To enable as many folks as possible, as soon as possible, to be able to save fuel by driving more efficiently because feedback from a MPG gauge is an essential tool for fine tuning ones driving habits.

Does anyone want to add/modify?

From that perspective though, I don't see that V2 has to be built on the same hardware as V1. V1 should be a compromise between cost/availability and time to market. There is every chance that v2 will be done on even cheaper and possibly better integrated hardware.

Also I think we need to consider carburetors. A mass airflow sensor is just a piece of heated wire with a controller (pic/stamp?) and may give an accurate indication of fuel flow once calibrated with a few fillups. Not perfect, but cheap and possibly quick. Is there a physicysist in the house? Could such a sensor be made and inserted in a fuel line, or is it gasses only?
