In short, no. It only pulls a signal off your WB.

Correct, it does not. The narrowband only has 3 readings anyway really; too rich, 14.7:1, and too lean. Not much use for tuning.

So if I pull it completely out of the car, it should be fine?

Yup, as long as nothing's reading it it has no purpose.

If i built you a standalone harness yes, you can remove it. otherwise the stock ecu still wants to see it. but with the lc-1 you can output a signal to the stock ecu that will make it happy.

This is a standalone. I have a four wire sensor in the car, so I have extra wires snaking through the engine bay for it. Will be nice to get rid of it.
