Does anyone know of any resource to look up actual harware specs for variuos Ford PCMs, such as to be able to see the differences between a MPC-14D PCM used on the 04 Mach1's and Cobras, and the MPC-15B used in the GT's, both of which use the FBFG2 strategy?

I don't know of any spreadsheets or anything else that lists the changes. Since you already know the application for them you should be most of the way there. Another way of researching would be to go through the spreadsheet that is floating around and see what other applications use the same hardware code but I doubt that'll get you very far. Basically you are going to have to figure out from what the cars have. Did they both have knock sensors? IRCM? Were the automatic transmissions different? Cooling fans (I rather doubt this one)? The other choice is to open them both up and see what "extras" are in one vs. the other.

There is a spreadsheet that tells which catch code belong to what hardware and what hardware is an upgrade for others but there is nothing i know of that tells the details of the hardware internals
