if you were going to use a wideband, you would use the signal from the wideband O2 sensor.

I dont think putting a narrowband gauge with a wideband signal will work. A narrowband o2 sensor operates 0-1 volts, while the wideband sensor operates 0-5 volts. The narrowband gauge would only read properly the voltage signal 0-1 volt rage from the wideband sensor, anything else would be off the scale and the gauge would not know what to display.

I havnt ever tried doing this but those are the facts that i know.

humm, what is the scale on the narrowband autometer afr gauge? rich, lean, stoich #'s.

i wouldnt see why you couldnt use the emulated narrowband signal, i did not know the lm-1 had that feature. you could use the emulated narrowband signal and compare the afr gauge to the wideband display, compare the two readings and see if they are the same.
