Does anyone have any ideas on how to measure the fuel comsumption of a DeLorean in such a way that it can be used in a miles per gallon calculation? I have seen something called a CIS air flow potentiometer on the CIS system for an Audi that is used for their trip computer but 'our" CIS system does not have that. Is there another way to compute fuel flow. Could I use the info from the frequency valve and RPM? I may put some magnets on the drive shaft and have a sensor read the speed of the car. Is speed information available from the automatic transmission computer? Thanks again, Dave 6530
