CIS Fuel System

["drdhdmd <doctordhd@xxxx>" <doctordhd@xxxx>]

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
