    LTG w/ E80 have WB O2?

    I'm seeing conflicting info on the interwebs with some folks saying this was added for '16. Does anyone know if the 2016 and 2017 LTGs with the E80/E80A ECMs have a factory wideband O2 sensor? When scanning, i do get values for a universal sensor "WB EQ RATIO", but the O2 sensor voltage does not seem to indicate WB. Thoughts?

    I have a 2018 Regal 2.0 ltg with the E80 ecm, and even tho it's not a supported vehicle, the few things the scanner picks up is lambda wb. works exactly like a wideband should. Hope HP supports this vehicle sooner than later.

    My 2016 Envision E80 has a 5 wire primary O2 and 3 wire secondary.

    Yes. Based on o2 sensor 1 wire count compared to 2013 ATS LTG. 5 or 6 wires vs. 4 for narrow band o2.
