So, I have a 2018 Springfield with no engine modifications what-so-ever and this isn't something I want to change. I like the airbox design and I love the exhaust note as-is. However, I really don't like that clack coming from the engine nor do I like the heat and vibration from the engine. All I want to do is enrich the air/fuel ratio so the bike runs better.

Now, I have purchased a PVCX but I need a map for a stock bike with an enriched mixture. I have searched online for such a map but have come up empty. I know that I will likely still have to tweak things afterward but I would like a place to start. My motorcycle is in the shop for warranty work (post coming in due course) but they are also going to upload this map file, if I can get one.

Does anyone possess such a map?

It doesn't work that way. You need to pair the PVCX with the motorcycle and download the stock tune to the PVCX and create a info text file to up load here.

You can't just use any tune because the tunes are matched to your bikes ECU checksum and tune compatibility.

Also most of the tunes are actually in open loop running the mixtures leaner than stock. The stock tunes run the mixture pretty rich in open loop which creates a lot of heat from the Catalytic converter. In closed loop the tunes retain the lean 14.7 to 1 AF ratio as the factory tune except for in a few places at low RPM

Yeah you lost me on that last paragraph. Are you saying that, by re-tuning the engine, I'm actually making the bike run leaner than stock?
Lean and rich are thrown around the internet without much context. The stock tune in closed loop is very rich. The stock improved tunes lean it more in this area for power as well as advance and retard ignition timing in areas. The improved stock tunes will improve torque and HP a bit. And cool the heat down because the CAT is not trying to burn excess fuel. So getting a PVCX for a stock bike is good, because of the above benefits.

"The stock bike runs lean" is a generic statement and is applied to all ECU motorcycles and isn't necessarily true for all of them. Usually when this lean term is used, it is referring to closed loop where the O2 sensor is used to regulate the A/F mixture. On typical rides most of us operate in closed loop. On the Indians closed loop is somewhat lean. But the PVCX tunes don't change this much at all. Most of the heat people complain about is the CAt, which runs hotter with mixtures that are richer.
