MIL Code 1 O2A sensor on decel, closed loop disabled

I haven't found the exact RPM range that triggers this yet, but I have seen it quite a bit, usually when I wasn't datalogging, so I didn't know what code was being pulled.. I think it happens about 4-5k RPM on decel with clutch engaged(not released). Further testing will hopefully reveal more info. It was my first datalogging test in the \"Pro\" version so I didn't have logging enabled. I have Closed Loop & O2 heater disabled and have PLX wideband output hooked to my O2 input. Rom version was ECT_273 .45 and .46 seemed to have same issue. Attached is my current CAL

Now that I have single car(Pro), I changed settings to wideband -> PLX and the problem hasn't returned yet..

settings doesn't change anything in the rom. If you said you enabled wideband closeloop or something then i could say yes. I'll debug and find it
