After unplugging all your FC crap, disconnect the battery for 15-20 seconds.  Then start it back up and allow the ECU to relearn the stock running parameters. 

You've probably got a lot of junk signals and codes stored in your ECU.

No dice. Removed the battery as well as the ECU, let them sit for a minute, put them back, same problem. Seems to be running fine, at least at an idle, but check engine light persists and EC39 pops up as soon as I shut the bike off.

[I see that there's no explicit rule against double-posting, but forum etiquette from my earlier days on forums persists, hence the edits in my posts]
Edit: In case anyone's curious, my plan is this. Since there's a light and an error after unplugging the PCFC, I'm plugging it back in. If it goes back to what it was doing right before I unplugged it--dying somewhat quickly at an idle, but no error codes or check engine light--then I'm going to start it up and slowly ride it down my street. If it dies while actually moving, then there's a problem. If it stays alive while moving, then maybe it'll idle fine in the garage long enough for me to put in Ivan's settings, and it'll all be fine from there.

If it either doesn't stay alive while running or doesn't idle successfully after going down the street, then I'll take it out again. If taking it out again brings back the check engine light and the fuel error, then I really have no idea what else I could do on my own, and will have to take a day off to rent a Uhaul and tow the bike to Manhattan.

I could theoretically just call Ivan and troubleshoot this with him, but a) the timezone difference means I'd have to leave work early to do it, and b) just ordering all the stuff over the phone was difficult enough; I have a fairly pronounced anxiety problem re: phone calls. Otherwise that's probably the first thing I'd have done rather than trying out all these other things myself.

Edit 2: Alas. No go. So I give up. Going to do what I can to find time off to rent a truck and a trailer to tow it to the dealership ~45min away. Hopefully they can figure out what I messed up, which I'm sure is something absurdly simple.

Edit 3: Dropped it off on Saturday [29 July 2017]; didn't even expect them to look at it until later this week, but I just got a call at 10:00 that it was ready. Turned out that, yes, it was something obvious, but it did require them to pull off the tank again, which was the whole reason I didn't want to try anymore. Cost me around 80$ in labor, which is well worth the savings in frustration. They said they rode it around for about 20 minutes and it runs fine. Now I just have to get a ride to the shop to get it...and then actually do Ivan's PCFC calibrations, but that's a struggle for another day.

I am not much more than a beast that has been taught to dance by blows and a few meager morsels.
