I turned on my closed loop O2 feedback for the first time in a long time. As I stopped in the garage I glanced at the wideband gauge and I noticed it get really rich, then a bit lean, then back to normal. I've got a plot of what happened. Can someone explain what is going on here? The fact that the EQ command goes to 0.885, then up to 1.089, then back to 1.0 is really weird. All of this at idle. Any insight would be helpful. Thanks. This is on a 2012 Corvette LS3 with a Vortech supercharger. Both narrow bands are installed and a wideband.
