I have a 93 grand cherokee. It came with a 5.2 and now I have put
a 360 out of a 96 pickup. Does anyone make a computer for this
swap? I have already changed injectors to a larger size (24gph) and
that helped, but I know it should run better than it does.It seems to be
held back around 4300rpms. I would sure like to know if anyone else
has done this sort of thing. THANKS, john

Just a guess but you could try pulling the computer from a 98 5.9 GC limited at junk yard or buy the replacment online.

You can also try haveing Jet chip custom program something that might make it work.
