'Split Oxygen Sensor output?
I would like to install a wideband oxygen sensor readout w/o running a second sensor. Can I split the feed, and send to both the ECM and a gauge? My headers are hot coated and I'd rather NOT have another bung welded in.

It depends on the controller, but it's doable. I know Innovate wideband controllers have a narrowband emulator output; not sure about others (I work for an Innovate retailer). The ECU and the gauge will need separate outputs since the signals they need are different.

Entering a new learning curve, here
Thanks for the replies.
How is that set up? I thought wideband referred to the sensor, a Bosch heated sensor and was capable of giving more detail to a gauge while reacting faster to changes in the exhaust gas.
I have some homework to do, I guess. By controller, you mean the O2 sensor?
The car has a '90 Camaro ECM with a modified harness, keepallowing a stock location (front of the passenger, under the dash). The rest of the engine management is relatively stock, despite the engine being far from stock. With this aggressive cam running the engine on the edge of a stock systems capability, I'd like to watch the air/fuel ratio more closely rather than wait for an O2 failure, or CE light.
Thanks for your patience with my learning curve.

btw, 600*F is ''generally accepted'' as the temp at which oem narrow band sensors start sending useful data (voltage)
