Each model year has 2 masks. An $xx and an $xxA. The 93-95 is an $F0 and $F0A. So 90 is an 8E and 8EA, 91 is $AF and $AFA, 92 is a $D0 and $D0A.
So as an example, 92 was initially issued w an AZZC broadcast which is an $D0 while a later change was made in the broadcast BPPA which is a $D0A.
The change in these broadcast codes happens somewhere in the 07 address.
This is why you can read part of the bin correctly with either version of the mask, but if you save one BC using the other mask, it will not run properly because everything beyond the 07 address is moved. So the VE tables, as an example, are wrong.
I use the displacement/cyl. and the injector size as a check that I'm using the correct mask.
