Default LC1 Question

Does the LC1 replace the existing 2-wire o2 sensor or is in addition to for advanced tunning. Im thinking that the stock ecu wont read it. Im adding a MS in about 4 weeks.

The LC1 has 2 configurable outputs. You set one to 0-5V for MS and the other you can configure for a gauge or to simulate a narrowband signal. If desired, you can feed the simulated narrowband into your stock ecu and remove the stock o2 sensor.

I just dont feel like welding in another Bung if its not needed, is the wideband the same size as the 2-wire?

No, the WB uses a 5 wire.

If you want to use a gauge and feed your MS you will populate both inputs on the controller so either you give up a gauge or you give up simulation of the NB.

Yes the wideband sensor will fit in the same bung as your stock narrowband.

Keep in mind. Innovate recommends having the WB o2 downstream further from the turbo than the stock NB sensor is. They reccomend 36 inches plus, and of course before the Cat. So a second bung is safer for longevity of the sensor. Many threads on WB sensor location, mounting etc.
