Multiple knowledgeable people just explained that no, you cannot. You're either very good at ignoring any information that doesnt suit you, or you're doing some expert level trolling. If you're convinced that a narrow band can be used as a wideband, go out there, prove your point, amaze the world w...

So a NB can be used as a "semi-wideband"??. Could you use a NB to read from 11.78 to 14.7 ??.

14.7:1 is NOT an "AFR"?

Fine, Fred, let me rephrase that; if the AFR is CONSTANT at 14.7:1... why would the [sensor] OUTPUT also not be constant??

OEM narrowband output oscillates because the fueling is oscillating.

I have some idea. Why would the output swing back and forth... rich and lean... if the AFR is constant??

I don't think thats true. The only reason they swing back and forth is because of the OEM ECU, isn't it?. Im pretty sure they could stabilize an output if the AFR was stable at stoich.

What are your thoughts on "tuning devices" that use NB sensors?

What are your thoughts on "tuning devices" that use a narrow band sensor?. Can a NB be "offset" to measure between, say, 12.0:1 and 13.0:1 ??

... anyone?

Is it true that NB and WB sensors are the same... and its just the controller circuitry thats different?
