Was there ever a AMC/Jeep inline 6 powered by the Chrysler Co. (Huntsville/Motorola) NGC PCM? It looks like even the 2006 Tj was powered by a JTEC II?
Are all OBD2 inline engines JTEC?

05/06 TJs with a 4.0 we're powered by an NGC controller.
JTEC+ was introduced in 99 and ran till 01 on the XJ chassis and through 04/05 on other platforms.

To my understanding the NGC has the ability to interpret above atmosphere manifold pressure and can be resscaled to handle up to 25psig. If the computer was configured to run a 4.0 has anyone retrofit one into an older jeep to run factory boost? Did the 05/06 TJ use a narrowband o2?

The TJ 4.0L running NGC used four narrow band oxygen sensors.

Is there anything really limiting the ngc from being installed on a 00 Or 01 Cherokee? It will run the coil rail and pick up the crank and cam inputs?

Some of the sensors are different so you would have to swap those as well. You would need a manual transmission version otherwise it will be unhappy about not finding the 42RLE TCM

It would be at a tuner to be rescaled for boost in sure there us a way to change the TCM part of the controller. This is just a thought I had kicking around for a minute but I am nowhere doing anything.

You're better off just rescaling the JTEC to handle boost.
