Why fuel trims don't work?

Hello everyone. Can someone tell me if I turn off the rear oxygen sensor in the Ecuflash, the fuel corrections stop working... Maybe i can't do this, but me need to put a resistor to deceive the ECU? I read somewhere that there were such problems with cars for California? Thanks for the clarification.
