Does anyone know of a way to adapt either a Hotwire Air flow meter or use 
a MAP sensor in leiu of any AFM on a L-Jetronic or Motronic ECU?  I need 
to get more air/fuel in my Alfa Romeo and have both systems available.  

I understand that the AFM controls injector duration based on air flow as 
measured by the deflection of the flap or cooling of the hotwire.  Simply 
installing a larger AFM would probably cause a lean condition, especially 
at part throttle.  Is it possible to add or subtract resistance to match 
the voltage curve to the increased air flow and what would be the easiest 
way to measure this? - o2 sensor? - EGT?

Be gentle, my electronics knowledge is basically ohms law and some vacuum 
tube theory.  OK, I'm old!
