Can LC1 be wired as both NB o2s?

Can LC1 be wired as both NB o2s? Ive had to replace nearly 20 oxygen sensors in the 50K miles since ive had long tubes. Im getting sick and tired of the sensors throwing codes after a month or two, then slowing down till they barely switch, or switch inaccurately. Im currently running open loop and I have my LC1 tapped into my X pipe. Can I split the analog output # 1 to feed both front narrow band o2 sensors at the same time? Id really prefer to run closed loop, but I just cant take spending all this money on o2 sensors!

Saved me quite a few bucks.

I'd image you might lose some resolution with splitting up the signal, or at least thats what I was told when I was looking at doing the same thing except instead of simulating another NB sensor, I was going to splice it off to a AFR gauge.
If it were me, I'd just get another LC-1.

because of how the PCM does its trimming and fueling, you cant do that unless you have two sensors, one in each bank.
reason is, the computer independently makes each bank go rich and lean to have it switch... having them the same as one side would confuse it.

Yeah forget closed loop. Just run open all the time. Once you have it dialed in, you can probably forget it.
If you want more economy, just lean up at low load points.

Im in open loop right now. I like the idea of running closed loop just incase since its a daily driver. The wideband is in the X pipe, so its reading the average of both banks already. The computer would likely just add or subtract from both banks equally. As far as resolution, id be going off the first analog output, while the second output goes to HPTuners, so resolution should remain unchanged.

im sorry but was somebody serious about an electrical signal losing resolution. You have to be kidding me. ITS NOT MECHANICAL. You can just run one or both outputs of the LC1 to the different banks, short the heaters with a good resistor put a heatsink on it and call it a day. Just for the record the only thing that will change if you wire this right is the load on the LC1's driver. And you can get around that if it turns out to be a problem(although you wont know until the LC1 dies). Therefore call Innovative ask them if its alright to put the load of two o2's on one output.
