In this case, AEM UEGO Gauge vs PLX. The AEM seems to read over a half a point RICHER than the PLX, even when the AEM was mounted AT THE END OF AN OPEN DOWNPIPE where it *should* read leaner, if anything, right? Then when I mounted the AEM in the same location the PLX was in, it reads WAY richer than the PLX. Im going to double check the calibration on the back of the AEM, but Im pretty sure its set correctly (P0).

one has a bad sensor, of caliberation os not proeprly setup on one of them.

Inadequate power/ground. I know the AEM widebands have always been hypersensative to their grounds. Unplug the sensor from the AEM and the display/output should read 14.6
