All MAF vehicles are sequential but not all SD vehicles are batch fired.. though it's nearly all of them.. as far as I know the one and only exception was the '88 Mustang which was sequential SD.

That's not true. Several of the early 90's vehicles that got MAF were still batch-fired. From '96 onward I think you can safely say that everything was SEFI.

All MAF truck systems are SEFI. I'm also quite sure that most if not every Ford MAF system is SEFI.
The old 2.3 Turbos in the Mustang/Thunderbird were batch fire, but they used an AFM/VAM which is not mass-air.

2.3 Mustang also went MAF in '91 but only the CA versions got SEFI.

I guess they are batch fire, but I still don't know of any other engines besides the 2.3 that are MAF and batch fire. No full-sized truck or Bronco was ever MAF and batch fire.

What's the reason for doing this? Emissions? Why not for the 5.8? I could see that in CA (emissions) but I am not familiar with MA. Doesn't seem right to support these configurations unless there was a compelling reason to do so for each state.
