Good catch on the EFI for the Fiero. I believe it was speed density system
and that uses a lot of implied data for the manufaturer. Ie they weren't
mass air flow. If a mustang system from a 89 to 93 manually shifted unit
is used then there should be few driving issues because the system is
adaptive and learns as it goes. Unlike speed density where your really have
to farkel with the innards of the computer and its data to make work. YMMV..
