Awesome..

I want a wide band so bad.

Which model would ours use? or are all 3 the same, but with different units for read out.

That innovative one, how much was it? Does it have a similar display? Can it supply the ECU with a signal like the PLX? Or is a seperate O2 sensor required?

The PLX seems like a good setup simply because it only requires the one O2 sensor.

I posted a thread about this... a while ago. The innovative one does have programable outputs for a 0-1v signal like the plx. The problem is that low volt signal is a linear signal and the stock O2 sensor is definately not.

I never got any straight answers on what the ECU would do with a wideband, linear signal... could work perfect, could not. I don't know.

I guess we could check with someone who has an FJO or similar setup with 2 O2 sensors and and Air/Fuel comp. If they could get mixtures between 10:1 and then as high as they dare on there wideband and read the voltages coming off the stock O2 sensor...we could graph it and see how different the voltage would be from the PLX linear graph...? Maybe....

The PLX one is pretty dang nice.
The Innovative setup provides some software support for logging the signal however, but I don't see much on display design, or size of the parts? (Do they offer a smaller display for your car?) Also it appears the Innovative setup is for temp use in your car. Not so much a full time unit.
The Aussie DIY is also nice, and has some display features I like better. (Auto dimming of the display, and a simple bar graph showing rich/lean along with a numerical output.)
I think this is something those of us who play with boosted cars can't live without anymore. They are much cheaper than a BHG, or toasted motor. (Ask me how I know.... LOL)
Looks like Santa will be buying me a new toy this winter... :)

Output from wideband:


Just extrapolate this to 0-1v.

Output ecu sees normally:


I don't see how these are going to work as a stock o2 replacement. The voltage in the middle would be the same, but the rest is inverted. I think that would wreak havoc on the ecu.

hey what do u guys think of this M-Series AutoMeter Narrowband to Wideband Gauge Converter are they good?? but damn cheap!





narrowband A/F gauge to WideBand converter


its only $35 plus shipping!!
You need the wideband sensor and controller for it to work. It just converts the signal so you can use the autometer dancing light gauge as the display. Not worth anything imho. Especially when the digital display is like 30 bucks extra.

I can't believe they would screw up on something like that. Are you sure? If that is the case their product features are a big waste of R&D time.

Its really not a big deal. Just go have the bung welded into the downpipe behind the stock sensor, itll be less than 30 bucks.

I have the original US DIY unit. I bought the converted Jaycar display, but I have been using a Megasquirt to datalog. I really want to find a decent analog meter to display the output, as this would be the most useful by far.
