Default Computer conversion?

I'm just curious, how hard (or impossible) would it be to switch a '93 computer to a later one (preferably OBD II)?

I'm just thinking, it's probably going to be hard to get my car tuned if I start doing stuff to it.... Would it be easier to tune/get the '93 tuned, or switch to a difference computer?

A 1993 has a whole different computer and wiring harness. You would need both and still have to do a little creative adaption with some of the leads.

Shbox is right you are going to need a different harness as to begin with the 93' is a SD car and does not have a maf you will need a maf and hookup for one on the later computers. If you are going to go that route I'd stay away from OBDII and go with a 94 or 95 OBDI comp as they are wayyyy easier to tune and the tuning software/equip is much much cheaper. Good luck!!!
