In all of the early 12-valve units, it IS possible to use the AFM from 
a 6-cylinder BMW of similar vintage because they both used the  Bosch 
L-JetTronic F.I. system. All you really needed to do was soak the 
Alfa's rubber inlet boot in boiling water to stretch it over the larger 
BMW AFM outlet and then using an air/fuel meter adjust the airflow 
screw on the AFM for best results. But in the early nineties, and 
certainly by the time the 24-valve Alfa engines came out, the switch 
had been made to the Bosch MoTronic system and I'm not sure that the 
BMW and Alfa Romeo AFMs are compatible anymore.  Anyone know for sure?
