I am a new member to this forum with an active interest in Propulsion technology and in Automotive industry in general. I have graduated in EE not a automotive engineer, so I hope you will forgive me for some of my questions or ideas that would seem bizzare or strange. I am slightly aware of the workings of EFI or MPFI engines. My question is that is it possible to calculate the instantaneous mileage
1) if we know the ratio of the Fuel Injector opening 2) if we know the fuel pressure in the common rail and hence the flow rate. 3) the distance travelled.
Is it possible to create a microcontroller based device that will take the above inputs, adjust for variations(esp. the fuel injectors) and display the instantaneous mileage.
