Simulated Narrow Band with LC-1 on an LS2??

[Rocketman69]

Ok.....Joecar has given me alot of help with this one, but I'm still having no luck.

Has ANYONE successfully simulated the NB O2 inputs to the PCM using the LC-1 in the stock O2 sensor location on an LS2 powered car??

The plug for the O2 sensor is opposite on LS2 cars than on the LS1s. Where an LS1 would have the male end of the plug on the sensor itself, mine has the male end attached to the vehicle's harness. The female end is attached to the sensor.

I used Joe's wiring schematic and the lovely diagrams he has provided, but I still can't get the LED to stay solid when the vehicle is started. If I hook the power and ground directly to the car's battery, it works fine, but not when it's connected to the sensor harness.

Any help is appreciated.

I have not seen the schematic you are using. It will probably work just fine on vehicles that do not have a "controlled" O2 sensor heater circuit. The newer vehicles have a monitored heater circuit that is PCM controlled. This amperage can be modulated and that is not a good source of power for your wide band unit. Just hook it up to a good constant 12 volt power source and you will be good to go.
