If you have any staged upgrades like S1-S3 then you can use the downstream 02 sensors bung and just ziptie the stock 02 sensor. You cannot disconnect the stock 02 sensor, but you can leave it plugged in and just tie it up and out of the way. If you still have a cat on your car, make sure the wideband is before the cat otherwise you'll get a false reading.
