I never unplugged the input to the LCDBC, just the sensor. The AEM controller supposedly outputs a 14.7 signal as failure management if you unplug it's input... I drove the car after adjusting it, and it appears to be accurate. Closed loop idle and minimal load are hovering around 14.6-14.8.

I'm just not sure I trust the other ends of the spectrum yet with a 0.8 adjustment...
