Hey guys,
I swapped a 95 zj 4.0 into my AMC and have hit a wall with the pcm. The zj computer that came with the engine has the security tripped. I am only using the engine, engine harness, and pcm from the zj in my car. My question is, can I use an obd1 xj pcm with my harness and engine, or maybe disable the security function in the pcm?

Thanks in advance

Im not as familiar with the zj sbec2 but I am surprised it has a sentry in it. It starts for 3 seconds then shuts down? What transmission did you use?

My understanding is that most zjs had security for the 94 and 95. Transmission doesn't have anything to do with it as it's a tf998 so it isn't hooked to anything. The cps is mounted on it and that's it.

Update: an XJ PCM will work on a ZJ engine and engine harness. I ordered a remanufactured XJ PCM off of a 1995, hooked it up to my Standalone engine in my AMC Eagle and it runs great now.
