I realise that B14 stuff is different to our Australian N15 stuff, but i use LC1 and have the factory O2 plug not connected to anything and i get no codes from my ECU. I imagine OBD II B14's would be different as our N15's are OBD I.
I like the LC1 for a few reasons over the factory sensor.
1. it warms up to a working temperature MUCH faster from cold.
2. you can set how fast you want it to respond (on the simulated narrowband output to the ECU)
3. wideband units last pretty well and you'll KNOW when the wideband sensor is going bad and replace it rather than finding your fuel economy going worse and worse.
4. wideband sensors are no more expensive than factory narrowband ones, infact my last wideband sensor cost me LESS than a narrowband.
5. why wouldn't you want a wideband gauge !
If you do get an LC1 though, check the firmware revision with the software. If its 1.10 and you have some problems with the sensor not reading after revving the car hard and backing off, you should look for the 1.20 beta update which fixes said issue.
