Hi!
I am doing costume turbo set up for my lt1 camaro. Its time to make up down pipe with o2 sensors. My 95 lt1 has 2 o2 sensors. so i was wondering if it is necessary to install both of them? Or i can get away with one? Cuz i was gonna install wideband too. I just dont wanna have 3 o2 sensors in a row if i dont have to. so if i use only one stock one what do i need to change in pcm(or not)?
Thanks ahead

or can i "T" wires together to one sensor?

You place the O2 sensors before the turbo and the wideband after.

If you get an open loop SD tune you dont need o2s, just sayin.

I thought placing o2 sensor before turbo will mess up reading and shorten life of the sensor?

yeah, but isnt it batter to have closed loop so your pcm can adjust for weather and altitude?

Placing narrowbands after the turbo will mess up the readings. If you wanna run closed loop you'll need an O2 sensor on each bank before the turbo. If it's a street car I don't see any reason why you'd wanna cruise around in open loop.
