    There is a new PLX that can be used with a laptop for $200.
    The PLX is not fancy, does not need to be calibrated and it just works.

    You can, but it is often considered, seldom done. You are probably better off with a separate bung for the WB sensor or use one of the rear bungs temporarily.

    The lc1 is in-expensive as well, but takes a bit to get set up right.

    A spare bung for the WB is not a bad idea. I run open loop full time and installed my LC-1's in the primary (BxS1) locations.

    My passenger-side NB O2 was dead, so I just put the WB O2 in instead ... no problem so far, works fine ...

    I just recently welded my LC-1 bung into the I pipe where there's a nice notch in the floorpan giving great room for install. I had it in the PS header but wanted to get AF of both sides combined. The sensor threads stripped taking it out of the header so a new sensor is in store before checking the difference from header to I pipe.

    BTW, if you need a replacement sensor and know someone with an account with NAPA, they are listing the 17014 Bosch sensor for 69.00 list and 42.00 cost for the shop I work at. After looking at Advance and Autozone for the same part I think NAPA has their pricing wrong so get em while you can. I ordered 3.

    For those kind of prices, you may as well get a second controller so you can see what's going on in both banks

    Just when reading one was enough to drive you nut!

    Did someone post that they used a WB o2 in the rear position? After the cats? I have always wondered if this can be done with any accuracy as the cats remove raw hydrocarbons not air. Many times I pull of the tail pipe to baseline a car prior to mods and it seems pretty accurate thus far. Any thoughts on this?

    I think pre or post cat comes down to splitting hairs, as many folks get similar results either way. My preference is pre-cat as it eliminates the cat as a potential variable.
