Nope, just the PCM and injectors. I believe that you can actually swap an 02 operating system into your current PCM with the right tuning software. If you talk to someone like Justin at BlackBear or Charlie Wheatley, they would know for sure, and could give you a good tune along with the 02 OS upgrade (back when I swapped in my 02 PCM, the tuners weren't as far along as they are now...at least mine wasn't lol)
