Thread: Terminator Dual O2 Sensors

    Default Terminator Dual O2 Sensors

    I'm just starting an install of a Terminator throttle body system on a LQ9. The installation manual show the 3.5" handheld being able to display dual WBO2 sensors, but I don't see how integrate the second unit into the ECU? Also, I ordered a Bosch 554-101 WBO2 and just noticed I was sent a NTK unit 554-100, if I can run dual sensors will the NTK work as a second unit? Any help or a link to an tutorial would greatly be appreciated! Scott

    If the ECU is a Terminator without transmission control, then it is the same as the HP ECU and only supports one WBO2 sensor. For you to use two WBO2 sensors you would have to have the Terminator system with transmission control, which comes with the Dominator ECU.

    Yes, and even with the Dominator ECU, the dual WBO2 sensors must be the same ones.
    May God's grace bless you in the Lord Jesus Christ.

    Thanks Danny. Looks like I'll be sending the WBO2 sensor back, as I don't have transmission control.
