Finding out Fuel Consumption.

[Bruce Bowling]

~ 
~ 
~ 
~ I dont know if anyone can help me, but Ill give it a shot.
~ 
~ I am currently doing a microprocessor project using an 8051.
~ What I am building is a simple Fuel / Trip computer.
~ 
~ I have a 1993 Ford Thunderbird with a 5.0H.O. engine.  Someone told me =
~ that Pin 34 on the EEC computer relates to how long the fuel injector is =
~ open. This in turn relates to the instantaneous fuel consumption.=20
~  Does anyone know of how I can find out more about the EEC-IV engine =
~ computer?  I know ford is tight lipped about these type of things.
~ 
~ Can anyone out there suggest a book that would help me out with this =
~ subject??
~ 
~ Any help would be greatly appreciated.

I know that the trip computer on Series III Jaguars tap right
off one of the injectors.  All it does is keep a running sum of
how long the injector is open, and, knowing the Lbs/hr rating
of the injector (times the number of cylinders), the computer
generates a guess of fuel consumption and mileage (distance is 
derived from the speedo transducer).
