my best guess would be is to have a good mechanic to read the rear sensor (guessing about .5 volts) then maybe if furnished that amount then the ecu might be ok and not set codes.
that is if the tune ecu will uncheck the number one o2 sensor.
Does the new US models have two sensors? It seems like the second one would be downstream of the cat, near it, to measure final exhaust levels. It could require having a welder put another bung hole in most exhausts to accommodate it.

If you eliminate the cat the rear o2 sensor will not work because the ecu is expecting a change producing about .5 volts.
on the 2025 is going to be a job to get it to work

Not sure if anyone here can verify, but when I called my dealership they said to pop the seat and if the plug cord was large and black it’s the Euro 4 version with one O2 sensor and it’s the Euro 5 with two sensors if the plug cord is small and red.

I am not a ecu programmer not even close i can barely hook up the tuneecu and check stuff much less than reprogram it
just wanted to share this i know about o2 sensors and if you change the ecu/pcm the California mod has the o2s that check to see if the front sensor is working.
