SImple question. I need to know what the output voltage is from the stock O2 sensor. KA24E

I'm trying to hook up my UEGO "controller" (really just a gauge) and I'm glad to see it had an Analog output. Only, there are many calibrations to choose from as far as how many volts it outputs.
P0/P1 output 0-5v
P2 output 1-2v
P3 output 0-1v emulates the Autronic Wideband O2 sensor calibration
P4 output 0-1v emulates a non-linear Nernst Cell calibration

When I wire up the analog output from the UEGO what calibration should I choose?

Thank you.

I dont recall exact one, but i know its in the instructions. Where are you puting it?> Dont put it in exh mani. I did and the ECU didnt like it at all due to heat. I think AEM says 36'' from motor.

Yes, the instructions include a list of "Analog Output Voltage Modes". Modes P0-P4 depending on voltage outputs and AFR/Lambda values. I need to know if I should choose 0-1, 1-2, or 0-5 volts. The mode I choose must be compatable with the factory ecu so I can eliminate the stock sensor. If the stock ecu recieves no more than 1 or 2 volts, and I have it switched to 0-5 mode, the stock ecu couldn't hadle it/understand it.

I'm getting all of my ducks in a row in order to go KA-T. I have a header on right now and the sensor will be installed right after where all pipes come into one (4-2-1) before the converter.

If you are trying to get rid of your stock o2 than the output signal that goes to the ecu will need to br 0-1 volt.....that's what narrow band sensors run at.
