You will be able to program any of them that came with EFI, the question will be whether they are flash programmable or need a chip. 94+ are flash programmable, and I know 92 and prior are chip based (require a chip burner). I believe the 93 is also (chip based) but not 100% sure.

nope won't work. The later style PCM that is flash programmable is for the LT1 motor. If you try to plug that up to an L98 you probably won't have much luck. One thing that comes to mind is the optispark. You can mount a flash chip on your memcal in an '86, but you'll still need to remove the chip to program it.
