I have an lc2 and for some reason it doesn't show any readings but lambda. I change it on the laptop and nothing changes. changed it in the laptop, then recalibrated the sensor and no change, tried recalibrating then changing on the laptop with no change. Every time I plug the laptop in to it the settings are on lambda again, even 2 minutes after I just changed it. gauge stays at like 7.6-7.8 constantly. sometimes it will show 10.8 out of nowhere. is there something simple i'm missing?
