Air-Flow meter interchangability

     This sounds like the Bocsh system also used on the older VW engines. 
I have found that these air flow meters are not exchangable in most 
cases. The Bentley manual I got for the VW has a list of the air flow 
sensor part #'s, and their matching computer part #'s, so if the numbers 
match, they can be interchanged. I don't think Bentley Publishing offers 
any Fiat books, If they do, please let me know, as I also have an X1/9 
and no really good book.
     The resistance is supposed to be linear, and those resistor pads 
wear about where you say, Where the arm spends most of its time. I have 
in the past gotten a bit more life out of one by shortening the arm, 
making the arm touch the resistance pad in a different place of the same 
resistance. This is generally wasn't worth it in my situation. The pad 
seemed to be equally bad in these spots. But take it apart- you may be 
lucky enough that it could work. 
     Please write me as I am interested in Fiat Spiders too.
