So basically, I'm lazy. I don't want to pull the header to weld in a bung. The LC1 can simulate a narrowband output via Analog 1. Is anyone using this feature with the sensor in place of the primary O2? Is the ECU happy with it and how are you getting around throwing a code for the heater circuit on the factory sensor? I'm guessing you could use a resistor for the heater circuit. Any clues as to what ohm it would take? What about just leaving the factory O2 plugged into the harness and tying it up somewhere out of the way while snipping the signal wire to attach the Analog 1 output from the LC1?

 

I tried to make this work in my Civic once but, the narrow band signal didn't work properly. The ECU didn't like it and it caused the mixture to hunt around instead of cross-counting (stock 02 sensor works by cross-counting, crossing the stoich line N times per second). I'm not saying it won't work for you AND maybe the simulated narrow band is better these days but, it didn't work for me.
