I'm installing a Lomas/Ott X-pipe soon, and it has two O-2 bungs. My stock O-2 sensor is rusted onto the stock cats, and the cats are being eliminated. I assume I'll need a stock O-2 sensor to work with the mostly-stock LH system?

In terms of the wideband, I've got a stock Sharktuned chip in the car now and I'm planning on future Sharktuning. I feel like I recall the Sharktuner manual recommending a particular wideband O-2 sensor but I don't have that handy.

Search, again, yielded about a million results. I need to work on that... usually I'm good at research! (I do it for a living... )

Thanks in advance!

Bosch for stock

 

Excellent, thanks Kurt!

And is that the Biltmore in your avatar?

 

As far as the Bosch one, Pelican lists two Bosch O2 sensors for my car. Is there any particular reason to get the 928 specific one? (at nearly double the price)

The universal sensor will need you to cut the wires from your old one and splice this into it. The more expensive is a direct replacement, complete with plugs.

 

I'd guess the more expensive one has the correct plug on it. The cheaper one most like has a pigtail that requires you to cut/crimp your old plug on to the new sensor.

 

Yup; thanks to both re: splicing. I don't think splicing wires is that big of a deal; any reason I should avoid that in this application?

 

Yes, that is the Biltmore taken prior to SITM years ago.

If you don't mind splicing wire, might at well save your money... you'll be down there hooking up WBO2 anyhow.

The hole you have to thread the wires through is small and hard to get at so it's actually nice not trying to squeeze through the factory connector.

When ready, cut your old wire and tie a good string to it and pull it through to the inside. Then use this string to pull in the wires for both O2s.

 

LSU-4.9 for the wideband sensor is probably the best.

Techedge's controllers have gotten better reviews from the people that I talk to than Innovate's.

 

Most wideband sensors have a narrowband output so you don't need both.

 

That is true, but WB sensors are notoriously unreliable and require recalibration from time to time.

NB sensors are simpler devise that pretty much just work all the time and don't cost that much relatively speaking.

Then again, one can simply run open loop and ignore the O2 sensor entirely. They don't help performance unless one considers MPG a performance rating.

In my mind max power is how performance is measured which often occurs to the detriment of mileage.
