1jz LC1 narrowband signal to ecu
I'm looking to eliminate the stock o2 on my 1jz since I hate to put two sensor bungs in the downpipe if it's not needed. I think that I can use the lc1 narrowband output to feed the ecu, but can I just leave the heater circuit unplugged(open), or will the ecu throw a code?

The lc1 o2 heater is pretty hxc.. So make sure if u do run both u keep them a good distance from each other. I'm running a aem comp so my setup is a little dif then yours would b.

odb1 usually shows the heater code, but only when you jumper the pins, at least on my aristo ecu the heater code is not one that just comes up all the time, but if I jumper it I can see it, so just see how it goes.
on another note, I am not sure how well the narrowband function will work, but let us know how it goes I am interested to find out. I once tried to do the same with a aem wideband but it wasn't correcting right for some reason, but I could have wired something wrong, you never know with these things, trial and error for the most part.
there is also a resistor you can put on the heater circuit to make the code go away if you do get it. I forget the specific resistance but it used to be on a thread on club-nat related to the tt ecu mod, but that forum has been down for a while. someone has discussed it in the tt ecu thread but I can't seem to find it right now but it does exist.

good luck, in the end I just run the 2, one heated for the stock ecu and one wideband.
I keep the wideband closer to the turbo, and the regular one further down. no issues and if you have on in there having another one further down won't create that much more restriction.
If you had both of them in the same spot side by side (same cross section), well yeah that would def double the amount of restriction.
