Default P2196 then now P0031, any o2 simulator?

Hello, I just turbocharged my car and it mess an o2 sensor, first it came with P2196 stuck rich randomly for a while and now it's always P0031 (Heater circuit) seem like the sensor just failed. I'm running on standalone ECU so I don't care about this sensor much but since I used auto transmission, so want to keep the CEL for some important warning.

Are there anyway to fake factory ecu that O2 sensor still working fine?


Thanks
