Reply to "OXYGEN SENSOR HELP NEEDED"

All narrowband sensors I know of read stoichometric at .5 volts which is the only thing thats important for closed loop operation of ecu's. The voltages before and after stoich may vary slightly but the ECU is looking for the switchpoint at stoich. The sensor should work fine. That being said, if you have the resources to get one I would reccomend a unit like the innovate LC-1. It is a programmable wideband controller which will output one channel with a simulated narrowband output but will give you a full wideband out put for a guage as well. Much better for tuning. They can be had for about $200.
