The short answer is NO! There are many wiring differences and PCM differences through the years and very few units can be exchanged.
I put a 92 computer in my 89 to get data logging capabilities and we moved about 20 wires at the PCM to get it to work. None of the injectors were even triggered off of the same pin! Also the cruise control was on the computer in 89 and by 92 it had moved to a external unit.
Don't ever swap PCMs in a 'Bird until you have checked the wiring diagrams. Even the 5-speed/auto, egr/non egr computers can have differences for the same year 'Bird.
As Kurt mentioned you can do many things with the EEC-Tuner if you know what you are doing or pay someone who does. It can access and change many functions of the computer.
