Default ECU question!?
Would a obd2 ECU work with an obd1 engine, I've heard of people getting a ECU jumper for obd1 ECU to obd2 harness but it looks like there are none for jeep that I've seen! Or is it possible to reprogram the obd2 to work with obd1? 1991 jeep to 1998 jeep
Thanks

If your planning on installing a complete 91 engine into a 98 then no you can't use them.
