1990 XJ performance chip

Does anyone know if any performance chips (particularly JET) will work with the 1990 cherokee computers even though they always list for 1991 and newer??

Will not. Read my response on the other forum. Too much to type again this early.

They always list for 91 and newer because 91-95 have OBD1 computers. You have a Renix. Very different.
My 96 XJ is for sale in the event you want something to restore or build into a wheeling rig. Sale ad is HERE.
