I'm a noob to wideband so bare with me. I know AEM has the kit for like $400 but bosch sells just wideband o2 sensors for around 100. Can I just buy that and use it for tuning? Or, does the wideband have different wires that run directly to whatever I will use to tune (in the far future)? Any other info is welcome too

That's just the sensor, you need something to convert the voltages to A/F ratios and that's why they cost more. Check out the PLX Devices WBO2, it's a little over 300 bucks.
 
i can also probably get you the AEM setup for around 385-395 shipped. let me know if youre interested.

Is there a time limit on that? It will most likely have to wait until after xmas.
 
the plx units are rather nice... i'm actually waiting on mine... you can get the for around 350 shipped... that's the unit that is coming in most new cars (ie vetts... mercedes)... i'll post again when i have mine and it's up and running

I've heard some really good results from Innovative's LM-1, its the Bosch 5 wire (think its 5 wire) wide band sensor with hand held logger with laptop capabilities. Has optional RPM pickup for some nice logging features. I don't have the LM-1 but I do use the Bosch 5-wire to monitor Lambda in my personal car (comes factory in my vehicle). Since I have it as my primary O2, I want to borrow different wideband systems out there and test differences between widebands.
 
got my plx last night... good unit... really helped me tune. percice readings, has both narrowband and wideband output (for your gauge of choice) and it comes with the ability to use it as one of your primary o2 sensors (in case you don't have a plug for a 3rd) it's pretty much plug and play.

The Innovative is sweet. It has a much larger range than the AEM does, and they are releasing a 52mm display that is similar to the AEM readout.
 
I know this is rather old but im about to buy this or a LM-1

Question about the PLX....

- is it a 5 wire Bosch wdeband O2 sensor?

- Is the O2 sensor plug and play? Meaning if the O2 sensor goes dead I would just have to order a new Bosch 5 wire O2 sensor.

- I heard of its Narrow Band feature, could you guys explain that in more detail? So it can be hooked up in the factory O2 bung (on exhaust manifold). and can be switched back and forth to please the factory OBDII/ECU? How does that work? I would have to replace the factory O2 sensor and the PLX will have to be tap/splices into it? IS this what you are talking about? Or does it have the option of displaying narrow band which is pretty much useless? And this means I still have to fund someone to weld a Bung onto my exhaust? called: Bung and Play?

- is it turely compatable with nearly all major EMS, Motec, Microtech, Haltech, hondata, AEM and etc.

Why am I asking this? PLX doesnt have a datalog unless you have a compatable EMS. I hope to get a LM-1 (hand control) for really cheap and that will provide datalog without a EMS. And the LM-1 uses a Bosch 5 wire WB O2.

I like the PLX display...nice and small so it can be mounted anywhere...perfect for the little pocket to the left. Im not a big fan of gauges fo wideband O2...too much clutter on the Apillar.

Does anyone have a picture of the install...expecially the connections in the back? What was the installation like...hard? Any taping/splicing or welding since they claim plug and play?

I went ahead and bought the PLX

Why becasue it can be placed in the factory O2 sensor...meaning I do not have to weld a bung to get it to work.

The M400 is wireless and has datalog...but the one I bought is the M300. It was a very good price so I went ahead and bought it.

I can always take the INnovate LM-1 hand unit and record my data because my firend has it and both run off a Bosh 5 wire WB O2.

Overall I love the looks and you can use any WB AF guage and also have a Narrow band to wideband converter you can buy...

has 2 outputs

<LI>
Wideband LINEAR Analog Output (0-5V)
<LI>
Narrowband Analog Output (0-1V)

instrustion on replacing the stock narrow Band O2 sensor with PLX.

you actually don't even need a "wideband to narrowband converter" the m-300 does it all. hense:

Wideband LINEAR Analog Output (0-5V)
Narrowband Analog Output (0-1V)

i have the same unit... i like it very much and it's rather cheap. i paid 350 for mine. sensor and brain.

Just bought it!

Have you replace the stock narrow band sensor witht he M300 WB O2?

no i didn't replace... my downpipe had a bung for it
either way it's not that hard

the ecu takes in a narrowband signal straight from the wide band... i would imagine you could snip the wire that goes to the ecu (from the sensor you replaced of coarse) and just run the gray wire to the ecu side of the one you snipped... (i think it was the gray one... could be the white one... just check the huge peice of paper that comes with it... it has good diagrams)

a word of advice... don't grab the power for the 02 controller from the ecu... grab it from the ignition... (that's what i did)
 
That I get but its the 20 ohm/10 watt resitor process that im kind of iffy about...maybe I should wait for it to arrive before doing anything.

Thats the only reason why I bought it...it was the same price as a LM-1 but you dont need a extra bung. Plus the only thing you need for the LM-1 to datalog is a Bosh 5 wire wideband O2...which the PLX system uses. And all I need is the innovate LM1 handunit, analog cable and software that my friend has.

Yup...good call on the wireing into the ignition harness...thats they only way I do things

I installed this to make sure my ignition harness doesnt look like crap:

M400 is freaking nice!
 
you don't need to use the resistor... since the o2 sesor will plug directy into the brain... it will get it's power from their to heat it up... good call on the ignition... where did you get that? how much did it cost?
 
Okay ill try that but that was form PLX website for using the M300 to replace the stock O2 sensor

Got it at pepboys...one of those things for ricers to plug all there neons in. Comes in a cigerrte adapter thing that I just cut off. And has a built in fuse. Bell makes it. It was like $11-$15 or soemthign liek that
 
nice....

yeah... i know that came from plx... it has a bunch of different diagrams... even one that shows the difference between a wide band and a narrow band... it will work with out the resistors... but if you wanna put them in they come with the kit. their are like 3 ways to hook this up as a replacement ... you'll see in the diagram... gotta go to pep boys now... LOL
