AEM is a company.

Wideband is a sensor which accurately measures your air:fuel. It's a tuning device and essential for modding anything beyond a stock fuel system.

I wouldn't say it's a "tuning device" but it aids in tuning. You can't use a wideband to physically tune your car, but it is needed if you do plan on tuning using DSMlink, SAFC, stand alone EMS, etc.

Note: This is different from an air/fuel ratio gauge that just shows lights. The wideband will actually output a number which is your air:fuel ratio as Mike said. This is what makes it usable for tuning over the lightshow air/fuel ratio gauge.

how would you install it on a 2g eclipse? where do I weld bunk on a Apexi N1 downpipe?

 

[No_Skillz]

You can weld a bung anywhere. However, too close to the O2 housing will decrease the life of the sensor due to excessive heat. Most recommend at least 12" away. Many people choose to eliminate the second O2 sensor and use the stock bung on the catback.

You can weld a bung on your downpipe (preferably in front of the flex section, but this has been debated) or you can use your rear o2 bung since you've already eliminated your cat.

Then why do they even make them if they are pointless and just for "show"? If it is just for suckers them I am one of them cause I bought one not knowing at myself

I am saving up for a wideband now that I know

I wouldn't say they're for suckers, but more for people who need/want a lot of gauges in their car. They are somewhat helpful (say, if you go really lean while cruising, you know you have a problem), but can't be used for tuning. Plus, people see the price difference between and air/fuel gauge and an air/fuel gauge (wideband variety) and think they're somewhat similar and don't want to spend a few hundred dollars for the wideband.
