    Hooking up a wbo2 for logging

    How would one go about hooking up a wideband O2 sensor so logging with tunerpro rt?

    from what I read, option 1: I need an immolator with a extra input.
    option 2: use the original nbo2 wire and change the ADX file?
    Option 3: ??

    The attached $E6 .adx TunerPro RT file is set up for WBO2, includes instructions (see screen shot). I would recommend installing an additional O2 sensor bung, so you have an O2 bung for each NBO2 and WBO2 sensors.

    Thanks Dave
    This pin B16 is on the ECM board? I will find it.

    Yes, Thank You.
    I looked at the wire diagram that is listed and I am going to add a bung so I can have two O2 sensors in.

    I know this post is old - but did the mentioned screenshot and .adx go away? Is there somewhere I can find it?

    Thanks Dave, I have had it in for some time now.
    There is a difference in my readings, wide band reads around 15.5 when BLMs are at 128, not sure if that is right.
    Truck runs good, but i would think it would have more power then it has or just wish full thinking.

    Not all wide band use the same math. I had to change the log file around when i used the newer X series AEM.

    I've noticed, more often than not, the WBO2 ARF and BLM's Do Not match. Tuning with WBO2 is very helpful for Open Loop, Choke / Warm Up, AE, & PE, when the BLM's are always set to 128.

    I worked the math with numbers from my WBO2 instructions numbers

    If there were no mistakes in the figuring you're good to go... I know ha ha. I thought the same thing that my math was good, but numbers never were right at first. Redid the math more carefully with help from a few posts eagle mark posted and like magic everything started to agree.

    The readings I was comparing the BLMs to are the WBO2 gauge it self.
    Idle BLM 128 WBO2 gauge fluctuates 15.5 to 16.5, driving is about the same.

    I posted some WBO2 closed loop tuning results, post #8 in this tread: http://www.gearhead-efi.com/Fuel-Inj...g-Dyno-Results
