1G Wideband O2

[laser4g637989]

I am wanting to put a wideband in my 1g, can I simply pull my stock one out and replace it with the wideband or should I just weld an additional bung?

On a stock car no you cannot do this. Ecu doesn't know what to do with it. ECMlink equipped cars can do this when set up correctly.

You would have to add an additional bung for your use.

From personal experience, even if you have ECMLink and can do NB simulation, I'd recommend putting your WB in a downstream bung and run both sensors. WB sensors tend to not last as long as NB, and WB gauges, at least in my case, can be temperamental and not always finish the boot cycle on first try (AEM X series in my case).

Great thank you!

If he doesn't have ECMLink or standalone ECU but doesn't want to add a bung, the only way is buy a wideband unit that comes with a 1v narrowband analog output, such as PLX.
I used to run the PLX wideband by only replacing the stock O2 sensor with the wideband sensor and ran a wire from the 1v output to ECU pin #4.

If welding a bung in is an issue, this is an option.

Not to mention two sensors act as sanity checks against each other, especially for exhaust leaks downstream but before a WB bung, but also for having the WB sim to check if the NB is still operating correctly.
The former is not helpful during WOT but at idle and cruise it can tell you whether you have a leak.
As said, only if you have Link or comparable ECU modification.
