    Default OL question????

    Is it possible to run 2002-2005 2.2ltr Ecotec engine's in OL-mode? I just built a stand-alone harness and I'm trying to figure out if it's even possible to run these motor's without an O2 sensor...I wonder If I unplug O2 sensor if it will just default to OL...
    Anyone?

    I think my P10 defaulted to open loop when I unplugged the O2 sensor, maybe try unplugging it and see what the fuel system mode is in the Scan tool.

    Thats your only option. Im running mine in open loop no problems . Just disconnect the o2. Watch it with a wideband.

    To bad you dont have the other tuning software. You could flash in a factory LD9 supercharger file, from a cavalier. It would be great for what your running, being a standalone.
