Pros / cons using the stock o2 sensor bung for you

[n2o_2k]

Just like the title says, what are the pros/cons about using your stock o2 sensor bung for your wideband instead of having a 2nd o2 sensor bung welded. (Planning on using the Zt-2 wideband).

if your wideband has something to convert to narrowband signal for your ecu, then just use the stock one. the reason why people use 2 bungs 1 for narrowband 1 for wideband is that your ecu can only ready the narrowband signals, and you use the wideband for viewing your a/f ratio on soemthing like a lambda meter for tuning. i beleive there are kits out there to turn your wideband signal into narrow band for using with your ecu while still getting the functionality of your wideband for tuning.

is it a good idea to always run a wideband 02? Or should it only be used for tuning?

just to clarify a little bit, my wideband got a narrowband output to feed the ecu. Any other opinions?

then just use the regular O2 bung.

yes you can always run on your wideband O2, i think many VW's use wideband O2's stock.
