Where can I get a wideband O2 sensor and for about how much?

Scott 89t2

the FJO system is around $700usd I think.

you can buy the DIY kits for a few hundred. but you'll be waiting months for the 02 sensor part is so back ordered. and I've never actully seen anyone finish one and have it working.....

I have the Techedge V1.0 system. I built it back in December. Just about when the demand for the sensor was lighting up big time. Took me a while to source the sensor but I did get it.

I believe the best bang for you buck is to build a Techedge system. I built it my self and learned a great deal about it.

The end of project cost was about 315. That was the kit, sensor, supplies, welding costs, etc......

My kit and display are built and work great. I wish I never spent the money on that Haltuner deal. At least I sold it on Ebay and recouped some cost!

I got my sensor from the partsbin.com

The sensor for the Techedge kit comes from the 93-95 Honda Civic VX 3 door Calif model.

And some random triva for ya....the RX-8 is equiped with a Wideband sensor...not sure what flavor though..

A *real* UEGO wide-band sensor costs like $1,000.&nbsp The monitor to read the signal is usually another $1,000.&nbsp If the system doesn't cost close to $2,000, it's not a true UEGO wide-band.

Huh? UEGO = Universal Exhaust Gas Oxygen sensor. The NTK L1H1 is only about $150, giving you can find one right now.

I couldn't disagree more.

I have a lot of respect for you Ted. I just don't understand where you're coming from.

You need to do your research on the subject.&nbsp There's been a recent uproar on "cheap wide-band" systems and kits out there.&nbsp I will only trust a wide-band system made by MoTeC, Horiba, Autronic or similar.&nbsp Everything else is crap.&nbsp Sure, it's better than the 0-1V narrow band O2 sensors on most cars, but what exactly are you doing with these things?&nbsp If you're trying to fine-tune fuel, you could run into trouble running it to the ragged edge.&nbsp I don't usually tune my customers' cars to the ragged edge, and I trust an EGT gauge more.&nbsp A lot of the "mid priced" wide-band systems/kits are based on the NTK 0-5V sensors off the Honda lean-burn VTEC and the like.&nbsp The GReddy AFR (analog) gauge is supposedly using this NTK sensor.&nbsp Temperature compensation is a big problem with some of the cheaper stuff.

Wow are you guys seriuos? Im getting my fuel controller soon and i was wondering about wideband o2 sensors to tune it properly but with prices like that ill just go to the dyno. What is a wideband o2 sensor i mean what does it look like and how do they work? Why are they so much money?

HeffBoost

Listen bud, I've done plenty of research and it pisses me off to no end for you to say that. Respect diminishing.

You made a point of the sensor itself being $1000 which is outright wrong.

Can you tell me what type of sensors MoTec, Horiba & Autronic use if not the L1H1 or LSU4?

They are just like a regular O2 sensor in size and looks but they have more accuracy hence you can tune with them. They give you an A/F reading and you can either lean or richen the mixture out with them.

Here's some reading for anyone interested.

Cool, so do they have like a read out or display, and with somthing like that then you wouldent even need a fuel controller like the apexi right? Cuz you say they can tune the mixture. If thats the case then i can see how they would cost so much

No you need something to tune the car. The sensor just give you a read out of the A/F ratio. that is where the S-AFC or AFR come in.

RETed

This is obviously going no where.&nbsp There are enough reference material out there on the web - you obviously can do a web search.

Ok, I have never done this. But has ANYBODY compared an expensive wideband unit to something that comes in kit form.

That would help a lot. Everything is just opinon. Money doesnt mean everything on somethings. I believe a sideby side comparison would be in order.
