Crank Relearn - Which Device?

[roaniecowpony]

I'm anticipating I need to do a crank relearn on the new engine I installed. I'm still a couple weeks away from starting it. But, wanted to get in front of this issue.

What's the best route? Which tool?
I have JSCAN, but it doesn't appear to have that capability.
Apparently JSCAN does do crank relearns.

So what other relearns do I need to do after a complete engine replacement with all new (to my PCM) sensors?

I don't have any direct experience with Mopar. Do your JScan. On startup, I suggest power on, hold for 30 seconds, no start. If no codes before, all sensors connected correctly, should be no new codes. Many sensors have a go/no go range. The computer will sort it out. Like a brand new start. Then do a start. Any codes/errors may sort themselves out. Hope that helps.
