Developments in architecture and/or maximum clock speeds can make big differences in processing power, without messing with the bus size.
It wouldn't surprise me if both ECUs had 8-bit processors... A more powerful processor probably would have been excessively expensive and just plain overkill. I doubt even the ECUs sold in new cars use anything beyond a 16 bit processor.

The 88-95 systems are referenced in there fuel and ignition systems in the same section. They do mention the only thing that has change was some evolutionary changes and ecu is now called a pcm. whatever that means. I'll have to find all the relevant data and post it. I'm not really saying anything. I can't read a manufactures mind. I'm just stating some facts.
