Wideband vs. Narrowband

[bronco9588]

I am looking at doing a squirt conversion, and everyone recommends the wide band O2 sensor. It appears there is quite a difference between the two. Does anyone know of a thrifty location for one, and what do I need to get it to talk to squirt?

it all depends where you live...
i bought a techedge unit, they are not cheap...but i bought local in case i had any problems, its worked nowfor six months without any problems. it was easy to set up, and only needs one connection to microsquirt.
try evilbay....with the exchange rate so low, you may get a bargain

So i am assuming that wideband require a controller as well? What sensors do cars at the junkyard utilize?

[pommie02]

most cars run a narrowband sensor.
so yes its best to buy a complete setup, controller and sensor.
you dont need a display, because megatune already has one.
you can buy kits to build yourself...but i cheated and bought one ready built.
i think with narrowband the update rate isnt that quick, so when you are tuning it isnt that accurate
and thet last thing you want is going lean

Do you know of any good (frugal) links that has everything i need. I am assuming i need a weld on bung, sensor, controller, and few extra wires?

For the thrifty type you might check out the JAW at www.14point7.com, there is a thread on this board about the JAW somewhere, and the guy who sells them posts here once in a while I think. I have one but have not had a chance to use it yet. It was pretty easy to build for what it's worth.

The sensor itself the cheapest place I could find was at amazon.com, shop arround because sometimes the same sensor with just a different lenghth wire can get different prices (+-$15 ish)

For a little more money you can get an innovate LC-1, which seems to come pretty highly reccomended by reading around on the internet, just my impression, your mileage may vary. If you buy the innovate I reccomend DIY autotune.

The LC-1's are great and if you still have a stock ecu which needs the narrowband input, then you can connect the second analog output to the stock ecu's o2 in. It makes it so that you don't need to add a second o2 bung provided the stock location is upstream of the cat.
