I had the local Jeep Dealership align the camshaft sensor and crankshaft sensor after I replaced the engine a few years back and, at that time, put in a Crown OPDA with OEM sensor and OEM Crank Sensor.
Amazon was running $100 off the AUTEL MK808S for Prime Day last month, so I pulled the trigger as I'd been eyeing it for a while in prep to pull the OPDA and check gear wear.
Yesterday, I hooked the AUTEL up to the Jeep for the first time in the garage.
This is at idle:
This is me bumping the throttle to get max change in the difference (pumped engine as high as 3k and this was the highest delta):
My understanding is that the dealership would have set the engine to DTC, align the OPDA using the locating pin, and then push a 're-learn' from the DRB tool.
The way I read the data above is that the OPDA is currently within +0.9 to +1.2 degrees of the crankshaft sensor.
Is all the above an accurate understanding of the data?

If the above is correct, when I remove the OPDA, I would set engine to DTC, drop something to lock to the OPDA pin, remove.
Then on re-install, would I get it back together and dial it in as close to the 13.7 it is at idle?
It's my understanding that the AUTEL can push a re-learn. I'm just not thinking I need to do that if all the sensors/OPDA that go back in are the ones that came out. Is that correct?
If I find wear on the OPDA and put in a new one, I would think then is when I'd push a re-learn. Correct?
