It hardly could be profitable if it is "kit" or smth like MPGuino or OBDuino, these project are created as "low price as possible" from beginning
ScanGauge (aka OverPricedGauge) is profit project, but not interesting for DIY'ers.
Probably we will also loose interest in this project after some time
Hopefully I will have patience to make fully functional "FuelMeter" in my car
