Why do I need a Wideband?

If you have a late model Z, then you have dual factory widebands that you could read. They seem to correlate well with my TXS tuner reg wideband in the range of 12.5 - 15.5. Above and below that, they don't do so well (range is limited). They are also not as accurate at start up. But they probably give enough info for diagnostics... (not for tuning)

It seems to me these days alot of people have widebands, but if they read 'out' they discount them as reading incorrectly. Alot just have it for show. Alot just have it cause they got caugth in marketing hype (markup anyone)? I know we got into them in the Honda scene, because DIY tuning is big.

I strongly disagree, I have been to at least 2 occasion that my A/F all of a sudden went lean for some reason, and the good thing is that I had my Laptop plugged in. If it wasn't for my Laptop started beeping (UTI beeps when knock is detected) I wouldn't have known it and kept on racing. Next thing I know my wideband was reading 12-13 A/F when on boost. I had to abandon my guys and went home right away. It is not just the tune but what if some parts in the car start failing (ie, injector, fuel pump, leak)? Do you really want to take a chance? Last thing you want is still go WOT while your A/F is very lean. I have seen many people here post having their engine blown and have no idea what was the cause because they don't have any gauge. To each his own but I would get at least 2 gauge and that is Wideband and Boost as bare minimum.

That's why its important to have the wideband o2 sensor in the most readible position (like the a pillar). Also, it helps to go out on a straight highway and drop to about 2-3k in 3rd gear and do a pull to redline while watching the gauge. This will help you get a better idea of your AFR over the entire rpm range since it's next to impossible to watch it on lower gear pulls.

one time I went to a reputable evo and subi tuner for some tapping of wires. left and noticed immediately something was wrong.af ratios were in the 18's. if I didn't have the guage I might have driven it a few feet further and would have blown the engine. best guage I have imho

any recommendations on which Wideband to get? You mentioned the a-pillar, but the only wideband gauges I've seen are square looking and don't have the same structure as my boost and etg will.

Good logging capability should be considered, as logging a 'run' is better than trying to eyeball the gauge and drive.
IMO, a gauge is cool to look at and good for adjusting small points like idle, etc. But in the event that something goes wrong in a hurry, you will not have much time react and 'correct' the problem considering piston speed / RPM, etc.
PLX has some nice devices (round) and LC-1, etc.

Like I said the price if the Tuner and Innovate isn't that much of a difference so not sure if you want to consider it. The Tuner from Turboxs will allow you to log your A/F with Utec. The Tuner is also very small that you can stick it anywhere and it has its own display that show your A/F. You can also buy this http://www.dynotunenitrous.com/store...?idproduct=170 if you want to hide the Tuner and have an external gauge that you can mount in your pillar. If you just want to monitor your A/F without any logging then just get an Innovate or AEM Wideband.

LC-1 for sure. Had some issues with mine, but Innovate replaced it. So far the new one has been working great. Got mine with the DB gauge, which is fine, but I wish I went with the XD-16 so I had some colors to look at out of the corner of my eye, instead of having to look at it directly to see the reading.

I didn't really care about the color since it can be blue and read Rich witch is good but it without really looking at the number then it could be 10.5:1 instead of 11.2:1, both by the way is rich...lol
