1 OR 2 Wideband O2
1 OR 2 Wideband O2 This has been bugging me alittle. using only one Wideband O2 say on driver side for tunning. how do you know the the other side is also ok without a Wideband O2 .
any of the AFTERMARKET Wideband O2 controls support DUEL SET UP?

FJO has a nice dual unit.
provided your injectors are all flowing about the same, 1 side is good enough, keep an eye on your short and long term fuel trims, and see if either side is out of balance of the other. If so, then you will want to swap the sensor, and make sure both banks are good.
If running a high hp setup, on stock rails, i would run the o2 sensor on the passenger side bank, as that side tends to go lean first due to the rail design.

Ryan....may I ask what you are basing your statement of the pass side runs leaner do to rail design from? My experience, from Nitrous perspective, is that the drivers side runs leaner. I say this because myself, and a couple friends, have had problems running nitrous on non-nitrous tune, or too much for the tune, and results in the drivers side plugs are the ones that melt, blow the ground strap off, suffer deposits from detonation, and or crack ring lands etc. Out of 6 separate incidents of plugs burning up it was all on the drivers side, with the pass side barely showing anything other than normal plug and combustion.
It may be different with badass NA setups or FI, but I would speculate they arent risking using stock rails at that point either, where Nitrous you get more out of them, even using a dedicated fuel system or not.
Curious about it, not calling BS, just sharing my experiences.
Bfly, I have been wondering about the same thing since I am getting ready to get HPT, I was wanting to make a switch box, like used for printer sharing. Although you can use the LTFTs to verify they banks are in synch, I would be curious if there is a difference, even the slightest in the LTFTs as to what it equates to in wideband, e.g. bank 1 LTFT -6.3 /// bank 2 LTFT -5.9. One bank may be running at desired 13.1:1 on street, where the other is running 13.8 or something. I worry about for the spray mroe than anything else.

When I was N/A, with stock fuel rails, my passenger side ran leanest (lower O2 Readings).
When I went FI, I also gutted that damper and increased fuel volume and pressure. My driver side went leanest.
It seems several factors can influence this.

Ryan, yep, damn I wasnt even thunking about that one either! Gees.
bfly- What kind of setup are you planning/do you have? If you have the extra cheddar, I would say its nicer, but its really not that needed (I'd go dual WB if it was less $).
