A bit unusual question, but I ask here because there are lots of engine guys with automotive industry experience.
So, we have the speed + elevation from GPS and the normal fuel usage data + weight of the vehicle supplied by the manufacturer. No rpms or throttle position.
How do you think one can make a very rough estimate on the current fuel usage on the fly?
I guess whatever is the formula will need lots of tweaking to be done and I was thinking about using Rfactor for it to simulate driving styles and so on. It will be lots of work I guess:)
Thanks in advance!
