best location for a wideband? ok well its getting to be that time i finally break down and get a wideband. but before i do i want to get everything inline and figured out. where is the best location for the wideband to go? as in EXACT location, if it is that important. i plan to put it on the passenger side seeing it has a little more room under there. i guess the only other issue i may have it getting a shop to weld a bung on for me since they dont like to work on catless exhaust.
also if i go with EIO for hp tuners, which i will, does it matter if i go lm-1 or lc-1? and as far as hook up for the WB, are there any instructions online i can check out? i assume it has to be wired up to power and ground and thats it?

I had some questions answered here:https://ls1tech.com/forums/sponsor-sales-specials/381558-innovate-wide-band-o2-sale-lc-1-lm-1-xd-1-a.html
I usually have the person get a bung welded in on the drivers side ypipe elbow after the header but before the bend on the outside of the pipe...that way I dont need to jack up the car & its in about as good a spot as you can get without hacking up the header.
Here's the link with my writeup. The LC-1 was my choice because I did not want an AFR gauge in my car (no real need for one).

The LC-1 kit will come with instructions, but you can go to Innovate website and download them if you want to see them before you buy. The kit also comes with and O2 bung.

you know now that i see those pics I kinda wonder whats better...to be farther up stream in 1 bank or farther downstream but reading two banks...anyone got an answer or theory...I personally would just read one...I think if you were to read both of them with one sensor your going to skew the final #'s...thats my assumption.

Verdad Gallardo Well, to quote Tim in my link above:
" just weld it in right behind the driver side header. It does not need to read both banks. And it needs to be close to the header to get the best readings."

I had mine welded in the driver's side leg of the Y-Pipe, prior to the cat. The WBO2 Sensor has to be mounted between 9 and 3 o'clock to keep condensation from building up inside it. I purchased the LC-1 with the XD-1 Gauge from Tim@EADPerformance for $360. The XD-1 gauge is really nice and has a lot of functions. I ended up drill a 2" hole in the TCS panel and the gauge fit perfectly. If you have subframe connectors, the LC-1 can easily be mounted about the SFC and secured by tie wraps. Then, I drill a 1" hole in the firewall and install a gromet. Route the wires through and make your connections. As much as I have been playing around with the PCM, I am running 11.9 at WOT. Check out http://www.innovatemotorsports.com/resources/lm101.php and they have some video's on the functions of the LC-1 and XD-1.
I chose my mounting location for keeping it the sensor out of the way and to make sure it was in the optimum position. I also did not want to do any drilling on my headers.
Now, I plan to get a QTP y-pipe in the future and will likely put the sensor on drivers side tube in the y.
I would definitely use the drivers side because cylinder 7 is the one most likely to run lean.
