2017 Focus ST Won't Pass NY State Inspection

I've been trying to get my 2017 Focus ST to pass inspection for the last 3 months. So far everything I have tried hasn't work. It's 100% bone stock, no modifications at all. I had the car 3 years, first 2 years I had no problem at all. Over the winter I had to get a small repair (charge pipe came off the intercooler and wasn't getting boost). Super simple fix, but my mechanic must have disconnected the battery to do it for whatever reason. Now I cannot get the O2 and heated O2 monitors to set readiness. I drove over 1,000 miles following the driving procedure and they never set readiness. My mechanic thought it might be a glitch, so he reset the computer and I started all over again. Now 400 miles later, they still won't ready. They logged the car and I logged the car with hptuners to see what was going on. Absolutely no codes, no CEL, no pending codes, and car seems to be working perfectly, Fuel trims are within +,- 3 for the most part, no KR, nothing. It drives perfectly and when scanned, it appears to be functioning perfectly as well, so I'm completely stumped.

Anybody have any ideas of what could be wrong? I don't want to just start changing parts, spending money and guessing, especially when the car runs perfectly. I don't know what else to do at this point.

I wonder if the car was tuned by the previous owner and had map switching on the fly? It could have been on a “Cobb stage one” type tune with all monitors enabled but got switched to a custom or “stage three”? No AP needed for these slot changes. Isn’t there a way to check with the RPM gauge?
Yes, the video I linked to goes over that process
The poster says it passed and set for two years then he disconnected the battery. I’m thinking it changed the map slot. That would explain his issue.
