         A friend with a 1994 Escort GT, 1.8 twin cam is looking to do some
 minor modifications.  The MAF is the flapper door style.  It has a 7 pin
 connector.  We pulled the other style MAF off a plain Escort.  It has a 4
 pin connector labled A B C D.  Is there a way to incorporate this less
 restictive MAF into the twin cam Escort setup?  I think they both have the
 same output, just concerned about the scaling.
         Anyother tips/advice is appreciated.

Here is a sight with alot of info on Bosch AirFlowMeters (AFMs) I think they
are identical to the ones Ford uses.  Actually, I think the Ford units even
use Bosch parts #s.

The problem is, I can't get thru to the sight at the moment.  I don't know if
they are haveing temporary server problems, or are defunct.  But it WAS a
great sight.
They had a chart showing the voltage to Air Flow ratio (what you are looking
for) although it would be different in different sized AFMs.  The reason for
the extra pins (i think) would be the Air temp which is used as a seperate
factor in the calculation when using AFMs, whereas with MAFs, this is built in
to the 0-5v output.  I am pretty sure AFMs also put out 0-5v.
Anyway, that's all I know (or think I know!)
