Replace NB w/WB or just add?

[Garry]

I'm ordering an LC-1 to put in my 'hawk, I was wondering: what would you say, replace one of the existing O2 sensors with the WB, or add it? Will the LC1 fit in the stock O2 sensor hole?

Hi Garry, LC1 can fit in the stock hole and you can wire it up to replace the NB. Or you can add a new bung. Any and all ways are ok.
I guess a separate bung in the cross over is best so you have a view of both banks.
I put mine in one side, up through the trans tunnel to the console. Its wired up as NB replacement. Though about 4 hours after I got efilive I was running open loop and have never gone back to closed loop restrictions. I dont use it, except to look at the o2 mv when Im feeling nostalgic.
So Summary is that you have lots of options, depends on how easy it is to install where you want it etc.

I replaced mine, permanent installation. Never seem to be done tuning. Just a matter of choice and how you want to use it.
