91 xj pcm swap
I have a 91 limited I6-4.0
What years and models PCM/ECUs are compatible.
I can get a hold of a 92 sport but i do believe that only the limited and the Laredo have the factory security systems in them and maybe some other options as well.

91-95 4.0 HO I-6 motors are identical. An ECM out of any of those should be a plug and play deal. Anything outside of those years I can't guarantee what will happen.
