    Default wideband- narrow sims

    Guess this is the right section for this. Anyways. I'm putting together a single turbo and getting a wideband post turbo. My question is. If i removed the stock o2s and just tie the signals together and then connect that to the wideband analog output. Will that work? Obviously the ecm wont be able to lean/rich each bank individually but should still be able to keep it in closed loop this way?

    Right. I know that they can send the signals to the ecm. But can I use that one wideband output to send the signal to both of the ecm inputs (inplace of the two stock signals).

    yeah i have 4 stock o2s. pre and post each cat. obviously the post o2s will just get zip tied to the frame. I would like to remove the pre o2s cause i doubt they will be accurate once being under pressure from being pre turbo. So i figured I would zip tie the two front o2s to the frame as well (to keep the heater circuit faults happy) but cut the signal wires, splice them together with the wideband output.

    if you run 1 turbo i should leave oem sensors where they are and run the wb at the downpipe ,

    wb for tuning /reading and oem for cruise afr
