Just before Phantom, there was a post about a wideband that had a programmable narrowband output. Anyone remember who made this, and where you could get it? Any details would help.
Programmable wideband?

i dont know if this is what you are referring too...this one has a lot of programmable options...narrowband 5 volt, display, etc etc....

I'm not sure if that is the one or not, unfortunately I didn't get a chance to read the previous thread, I just skimmed it at the time. 
This might do the job, though. I'll dig some more.

are you thinking of the AEM UEGO? it has both wideband and narrowband outputs and i remember someone saying they were using it as their sole O2 sensor, outputing it to the stock ecu.
I don't think so - many widebands have a narrowband output, but what I was looking at was a programmable narrowband output.
The idea was, as our ECU adjusts fuel delivery in closed loop mostly based on input from the O2 sensor, that this would allow us to adjust what the ECU sees and hopefully get the car running leaner while in closed loop.

pretty cool stuff...
Ideal is confused about his own link.
The narrowband output is 1v on this.
The narrowband output is 1v on this.
A synthesised narrowband (NB) voltage is produced by the onboard microcontroller using a 10 bit A/D converter (10 bit PWM converter with single pole filter), and a 63 word lookup table (with linear interpolation).
The NB output is designed to be compatible with the raw output of a Bosch LSM-11 sensor. Refer to this eXcel spreadsheet (mentioned above) for a graph of NBsim vs AFR.
