Scott,
I noticed on the your wiring diagram that only the heater ground goes to a chassis ground. All the other grounds seem to terminate in the EIO connector, which doesn't have a chassis ground. Is this correct? I've heard the term floating ground, could this be one?

Running my LM1 today as a narrowband. Everything went good up to the end where I had to sire the anolog wires! I hit a wall there, I have 3 wires, bare (ground) Red anolog 1, white anolog 2. Well now I have four wires on the stock 02 sensor and I have no idea which one is signal and which one is sensor ground? I know there should be heater 12V and heater ground also. Anyway I had to leave the project as it is until I figure out were my anolog wires go. BTW I put it into the passenger front 02 sensor hole. Anyone can help it would be great.

The narrowbands switch because the PCM slaps the fuel
around to make it so, because it needs it so, and lets the
cats scrub it out.
If you liked cobbling you could make a "narrowband" output
off -any- wideband signal, using a comparator IC referenced
to the 14.7:1 voltage and an output network that produces
a 0-1V signal. Something like a LM339, couple or three
resistors.
After putting headers, I find my NBO2s switch much slower;
only at higher RPM do I see fast switching, low gas flows
are lethargic due to sensor cooling effects.

if you are using the lc1 as a narrowband you also need to change your o2 switchpoints in your tune to all be whatever your lc1 narrowband crossing point is...somthing like 451ish I think is teh default value in the lc1 narrowband side
