Default Running good yesterday, now idles at 21.99 AFR

Tried editing the ve table for the RPM/KPA range it was in with no effect. Does this sound like a bad ground? Or maybe a wb calibration issue?

Yer wideband is fuxord. On my LC-1 when the wire got disconnected, it dropped to full rich so I'm betting something is wrong with the controller itself. Try recalibrating and get back to us.

WB calibration. The motor will die out right around 17-18:1 AFRs, and it will bog/choke around 9:1. Anything outside of that range is a sensor error (provided the motor still runs).

In addition to showing 21.99 AFR it was also running like crap at idle. As I was re-calibrating the LC-1 I also realized I had apparently had a stroke at some point during the tuning process. After re-calibrating and reversing my idiocy it is now running much better.
