LC-1 Wideband problems...

LC-1 Wideband problems...
Just put in the LC-1 from Innovate today and like the instructions said, i connected the "analog output 1" to the wire on the o2 sensor on the header, to simulate a narrowband. Few questions though...
Am i supposed to put the wideband sensor in the first o2 bung, on the headers?
If so^ which color wire am i supposed to connect the "analog output 1" wire to?
Is the narrowband display supposed to look like this?
--This is at idle BTW--
My wideband reads
I need help desperately!!!! Thanks in advance

FI --> 36in DOWNSTREAM of the exhaust port (due to increased EGT's)
in most cases you install a bung somewhere in you downpipe or just before the cat.

I took out the second o2 sensor and mounted it in the car, then put the wideband o2 sensor in place of it. The bung right before the cat by the way. The narrowband reads the signal from the first o2 sensor right?
When i'm at WOT the wideband reads around 12.0 but the narrowband reads almost to the max side of rich....IS something wrond? Thanks!

btw, what did you do with the OEM sensor? can i buy it off of you?

CEL just went on after 20 or so miles. i don't have a obd2 scanner so i might not be able to clear it unless i do a trial and error process.
^ i have the stock one mounted in the car now. Seems i may have to get it installed by the looks of things..
And a short vid of how it reads at idle..

i wouldn't use it for tuning a SAFC by any means; but if you feel comfortable doing so then go for it. it gets a bad wrap because:
#1 it's not accurate
#2 too many people decide to tune the car with it, not realizing it's deaccuracy, and go melting stuff or getting knock because they aren't paying attention to how lean they are truly running.
#3 it's not accurate
i just don't consider a safe method of tuning your car whether you are NA or FI.

Airlinevomitbag,
"Conventional (narrow-band) exhaust gas oxygen sensors have been widely used in automotive applications since 1981. Conventional sensors have one to four wires and can only sense air/fuel ratio over a relatively narrow 14.5 to 15.0 range. They are intended to be used with 3-way catalytic converters that require operation near the stoichiometric point (14.7 air/fuel ratio). The range of narrow-band sensors is inadequate for performance tuning. While originally developed for lab and specialized automotive applications, wide-band sensors are ideal for tuning."
have you done your research?
