93 lightning pcm

so I am looking for a 93 lightning pcm and I see that there is 5 different ones, and one being for maf, so my question is can I use say
C3P2 5.8 1993-95 Lightning SD-Bank / E4OD / F3TF-12A650-AC
instead of
C3P1 5.8 1993-95 Lightning SD-Bank / E4OD / F3TF-12A650-AB <-- the one I have.
the c3p2 is more easily found then the c3p1 or do I need to stick with the correct matching one.

Chances are the C3P2 is an upgraded pcm to your current one. It may also have a few other sensors installed to help with the pcm algorithm. It may work perfectly or it may cause a CEL, or not work at all. Best bet it to contact the pcm manufacturer and or the seller and ask the differences between the 2.

don't play well w others
maf and map are 2 different computers, and begin half year 94. the maf and map systems are not compatible. You also need to have the proper program for the transmission whether you have a e4od, or a fr70 w.
Like Doc said you would be best talking to the pcm rebuilder for your best fit
