Default anyone here have a westach AFR gauge

Mine behaves weird. It is hooked up to the narrowband output of my AEM.

It starts ok but after a few seconds the sensor warms up and the needle begins to swing to the lean side (because engine isn't running) and then suddenly it becomes pegged at full lean. It never moves from this point once the O2 sensor is warmed up.

The WB02 signal to the ECU is correct.
