nice write up.. got any pics of your install?

Just a heads up, many companies, including my Zeitronix wideband, have failed to succesfully allow their products to simulate our narrowband signals. Most all will advertise that it will work, but only a few people have successfully got it right. The easiest and most common is to weld the 3rd bung in for the wideband.

I second this statement.
The safest way is to do so.
Weld a bung is relatively low cost $30.00 and a wide band o2 sensor is only $55.

Very nice write up. And i assume it works flawless? would be nice to have this on the e-manage FAQ or something like that so its not lost!

I added it to the turbo faq so it won't get lost...

You da man!

BTW maybe we could gather some known good Air / Fuel ratio numbers if anyone has some to base for All motor, boosted, and No2? IM kind of curious what others read for A/F like at cruise not under load, and when they let off of the throttle to coast down . Mine reads ultra LEAN to AIR! on deceleration.

It's supposed to lol, even stock it does

Then, by doing this the wideband will be only to be connected to a gauge to know the a/f ratio, but the ECU will not read anything from it, right??

Thenk the resistors and capacitors in the DIY are not necessary?

No, only if you want to replace the stock o2 sensor.

Ha, feel like a two year old kid but... I'm not even two with Hondas, so here goes.
What the hell is a wideband?
lol
Thank you.

Its a tool used to measure the Air Fuel Ratio of the exhaust gases

Also when used with a dyno it allows you to tell whether you need to advance or retard your ignition timing based on the air fuel curve.
