Thread: Do I need new WBO2 sensor with Terminator Max?

    Default Do I need new WBO2 sensor with Terminator Max?

    I currently have Holley HP EFI installed and I'm 'upgrading' to the Terminator X Max, so I can have proper DBW control, tired of the little issues with the factory PCM controlling my DBW. Anyways, I see that my HP EFI used the 554-101 Bosch sensor, but the new Terminator's use 554-155 sensor. From what I understand, the 554-101 is the older Bosch 4.2 sensor and the 554-155 is the newer 4.9 sensor and are not compatible? So I'll have to remove my old sensor and plug in the new one included with the Terminator, correct?

    Correct, the Terminator X Max uses the Bosch LSU 4.9 WBO2 sensor. The Bosch LSU 4.2 WBO2 sensor is incompatible (LINK).
    May God's grace bless you in the Lord Jesus Christ.
