I've been wondering what data the trip computer uses to calculate the economy. On Prue the computer always indicates way too much, on Piper it just seems unreliable. I always calculate myself when filling up, and this rarely matches the indicated consumption.
Obviously the distance travelled is one of the inputs. But I would think the fuel rate would be too small and with too much variations to be of use. Not sure if the GEMS actually knows the fuel rate or if it just adjusts from it's base set according to the current operating parameters.
Perhaps airflow could be used, considering the ideal mixture is 14.7kg of air for every kg of petrol.
Any thoughts welcome! :wink:
