Just wanted to know opinions and thoughts on a wideband...

Is it necessary to have a wideband installed on a daily driver street car?

I am running Ectune..

What benefits will a wideband give me.

Also, what will a wideband be able to monitor and what symptoms or problems can it bring to my attention?

This for a boosted D series

a wideband will offer you NO BENEFITS other than knowing what your exact air/fuel ratio is.

You're tuner will/should install his wideband o2 sensor during the tuning session.

I don't know if you think a wideband o2 is some magical device or something, but its strictly for monitoring your air/fuel ratio.....thats it.

In my opinion a wideband is a good thing to have. Especially on a turbo setup. When in boost you should occasionally check it to make sure you aren't running too rich/lean. Now its not a diagnostic tool so won't tell you what's wrong but it allows you stop a problem that's arising before you do too much damage.

That's of course if you are using a wideband with its own sensor rather than an air/fuel gauge which taps into an o2 sensor. Those things don't read accurately.

My cars never been the same ever since the original owner spliced that craptastic A/F gauge into my O2 Sensor. I've replaced both sensors twice and the cat once and still NO pass! Constant O2 bank 1 heater circuit code!

I'm buying 1 more and that's it. Me thinks it's time for a swap anyways.

Check the harness by the computer. I could have been spliced there and its not making a solid connection.

I'd say widebands were a good thing to have, if I wasn't constantly changing the o2 sensor on mine and I don't even use the thing in a daily driver, I only use it to tune cars.

The new (square plug style) sensors last a little bit longer, but they're also more expensive than the ("D" shaped plug style) old sensor.

I don't run a wideband setup in my car, which is a high compression boosted b16 daily driver and have never felt the need to, as your tune won't ever just change itself. Once its tuned properly and well theres no need IMO for a wideband in your car everyday, unless you like replacing the o2 sensor every 6 months. I replace the sensor on my wideband at least every 6 months b/c I find it looses its accuracy after that long.

If you notice your wideband reading is different or changes from day to day or even minute to minute, thats the first sign that your sensor is dying.

This is just my opinion, based on my experiences.

But the "honda-tech" thing is to have a wideband lol

We have a wide band in our MR2 with seperate module which we can access and read seperately via lap-top, or watch it through the megasquirt ecu, via lap-top. We've had a few issues with connectivity, and the module itself had to be replaced once (for free, thanks to innovates great customer service). I believe it's giving us grief again, but this time it is due to the fire at shannonville (wires got a little crispy) and we just have to replace the sensor.

We only use it for tuning as well.
