I see that you can have the LC1 simulate a narrow band for the PCM to use as one of the front o2 readings. Since I don't have a third bung for a wideband I am using a bung for my o2 sensor. Is anyone using the LC1 this way? If so how did you wire it? I know the yellow wire from the LC1 is 1v narrow band, where does this need to go? Any other wires that have to be hooked up like signal ground or something?

These are the o2 wires I see in the pin out:

HO2S HI SIG
HO2S LO
HO2S LOW CTRL

Thanks!
