RB25 o2 Sensor Simulate with LM-1 Wideband

[fliprayzin240sx]

I got an old Innovate LM-1 wideband sensor with a simulate narrow band out. I'm attempting to use it to completely take the stock o2 sensor out. From what I've read so far, pin 29 (Exhaust Gas Sensor) is the o2 sensor signal. If I disconnect the stock o2 sensor and tap my LM-1 into pin 29, would that work or would I get a check engine light and make the car go into limp mode? According Innovate, sometimes the ECU would sense that its not seeing the heater wire on the o2 sensor and that would trigger it to go into limp mode. Just want some suggestion, ideas or info if anybody has done this before...
