The easiest way is to drive at a known speed, take a guess at your mpg and look at the instant raw data, then "do the math" as they say. Jot down the numbers and take it to the bench.

Lets do the easy one first:
So lets say you saw VC=20 at 30mph with the 1/2 second refresh rate, well that would be 40 tics/second or 144000 tics per hour. So divide by 30mph and you have 4800 tics/mile.

Injector is a little trickier, not exactly sure how to explain it but anyway:
Lets say you guessed 40mpg at the 30mph. The injector uS said 20000. So if you drove like that for an hour, how much gas would you burn? 30/40 gallons? I cannot properly describe the conversion at the moment.


Only the testers will have to suffer this though, I hope we will have a wiki or other tool and possibly an online calculator to help folks just look up the values for their car. I would also like a "quick and dirty" setup mode in the guino at some point.

Also, I would like to explain better any discrepencies in computed from injector flow rate values and real world values at some point.
