There is a guy at my work looking for a **cheap** wideband O2 sensor to use to tune his integra, he claims the chepest he has found is $ 1500 now he didnt specify if it was a kit for Air/Fuel or just the sensor but from what i have read on websites it the kit that costs that much, anyone know of somewhere to buy just the sensor?

My roommate uses one on his '03 cobra...he says it works really well...and the best part...it's only $349!!

 

Search for DIY WB on the web, and possibly on here. Prices vary, but they are a lot less than $1500.

 

NAPA or CarQuest will have a generic O2 sensor, I guarantee it. It will be about $70. Definately under $100. $1500 must be for the kit... but hell the SMT-5 and the O2 sensor I got only cost me $400 with all the install stuff. By the way the SMT-5 measures your AFR. Tell him that $1500 is ridiculous just for an O2 sensor and a way to measure it. He must be looking at something else I'm thinking for that price.

I bought one a few months ago from TechEdge (http://www.wbo2.com). They just came out with a new 2.0 version, and I just got it debugged. Very nice and the whole prebuilt kit w/Bosch 6 066 sensor is less than $500.

<edited> Sorry, bad link before.

 

Wide band O2 is one of the best tuning methods I have found to date. I just picked up a really cool kit from INNOVATE MOTORSPORTS. The total cost is only 349 and you get everything needed to do really fine tuning. Including datalogging... the box is new to the market and they are still developing the interface to log RPM along with air/fuel but they expect it to be avail. next week.

Check out my site for more information about this unit and how I am using it...

I purchased the Bosch 6066 wideband sensor (used on VW Jettas) for about $25. I had planned on buying the TechEdge 2.0 DIY kit for $150, but have since changed my plans and will be buying the Innovate Motorsports unit in the next week. I've been hearing some good things about it on other forums. That unit has a display, datalogging, the Bosch sensor, all wires, etc for a great price.

You can definately get a good wideband setup for under $500 unless you are looking at the Motec, FJO, or Autronic widebands.

 

I want to get one, but don't know which is best either.

The TechEdge V2.0 PRE BUILT unit was $457.00 US and included the Bosch 6 066 sensor, WBO2 measurement unit (electronics), separate display unit, all cabling, interface cable for pushing updates/calibration/etc, and shipping from AUS.

All I needed to do was to run all cabling, weld on the appropriate new bung for the new sensor.

LESSON LEARNED... I have a dual-cat 4Runner, since you definitely want the wide band O2 sensor in front of the first cat, you will save yourself some time to pull the short/front cat assembly out to drill and weld the new bung in place. It is very tight quarters between the exhaust manifold and the front cat. If anyone is interested I can post a photo.

 

Chris,

I realized I never answered your question regarding which is better... Like so many things, it depends.

6 months ago, it didn't seem like there were many choices. You could either pay $1,000+ for a "commercial" unit or you could go with the DIY-WB kit and build it yourself.

The "commercial" units were preconfigured/prebuilt with simple AFR data only and were running $1,000 plus. Pretty reliable solutions, not a lot of bells and whistles. These included FJO, Motec, etc.

Now in addition to the two choices above, there are a couple of other options including TechEdge WBO2 (significantly improved effort that started with the DIY-WBO2 world), Innovate Motorsports, and a third that I can't remember. The latest version of the TechEdge unit and the Innovate Motorsports devices are both brand new and have (or are working quickly on) new features.

So, the "it depends" statement means that you should first figure out what you want from the wide band unit.

• Do I just want AFR?
• Do I want RPM data recorded?
• Do I want MAP data recorded?
• Do I want MAF data recorded?
• Do I want/need internal logging capabilities?
• Do I want an independant display?
• Do I want to log to a PC/PDA/both?
• Do I want to use this an input to a piggyback/ECU?
• If yes, does it require the device to emulate non-wideband input?

Of course, I didn't know about all these questions when I bought mine!

If you have some of the requirements above, you can then start to dig through your options. And for the two new ones, the responses are still evolving. That means that you need to make sure it exists today, verify that someone is using it, and make sure you know about anything else that may be required to make it do what you want (including any new cabling).

I hope this is useful, I really like the new units and think they are giving everyone interested in tuning better and better tools!
