    Default WBO2 Help

    Just wondering if my unit is capable of running two WBO2 sensors or not. It's a Terminator Stealth 550-444K Master Kit, shows two sensors on screen, but running only one. I would like to put another one on the other bank to monitor the system. I was looking at my programing, and it says that it was using a Dominator setup in my ECU. I'm running the Bosch WBO2 sensor that came with it. Do I need a jumper/Y plug to run another sensor? Thanks, Al

    Only the Dominator ECU is capable of running two WBO2 sensors.

    So does that mean I can or not? Just saying cause the ECU is set on Dominator, and I didn't put it there. It does have the option for me to turn it to HP, I don't know if this is some of my problems with this system. If I can run two, I'd like to. Just makes it easier for tuning purposes. Still very dissatisfied with the EFI system, but trying to get it figured out so maybe I can love it.

    No, you don't have the Dominator ECU (Terminator Stealth 550-444K Master Kit), nor should you have it selected in Engine Parameters.

    I didn't select it, it was just showing on the parameters. So this means I should be adjusting my Global File and downloading it in the car with correct parameters?

    You stated you didn't select the Dominator ECU, so what parameters are wrong?

    I was looking at my programing, and it says that it was using a Dominator setup in my ECU.
    In the ECU Configuration screen, you should have "HP" selected as the ECU Type.

    I'm running the Bosch WBO2 sensor that came with it. Do I need a jumper/Y plug to run another sensor?
    In Engine Parameters, you should have one Bosch WBO2 sensor selected.
