1988 4.0l Jeep engine running on a GM PCM.

I put a 2004 Astro V6 computer and harness on my 1988 MJ 4.0l engine. I had to make a crank reluctor and a mount for the crank position sensor. So far I've ran it about 2000 miles with very few issues. The biggest issue is, I've never tuned anything before. So it's a slow learning process.
