Shopping for wideband

[the head]

Saw this on Ebay:
http://cgi.ebay.com/ebaymotors/ws/eB...spagename=WDVW

Looks like "it's all there". I like the fact that I can download onto a PC (laptop), then I can analyze runs. Cheap too.

Jegs and Summit sell the AEM for about $447 plus shipping. There are the same AEM meters on Ebay for about $420 shipped.

Anyone know of some other good deals out there? The first one is leading the charge just because of the PC ability.

OK found the manufacturer:

Read some bad things about the Innovative product on the net - but great things too.
Here's another :

i was about to mention the zeitronix one, but looks like you already found it. some of the ls1 guys have been using them. you just want to make sure that the output of the O2 is compatible with an engine management program that you'd probably want to use later. good luck.

All Titans have factory wideband O2 sensors.
The O2 sensors on Titans already are wideband. It is possible to use an OBDII scan tool to read the wideband signals.

350Zs switched to factory wideband O2 sensors in very very late 2003 when Nissan moved to the 8MB ECU. All Titans have the 8MB ECU and wideband O2 sensors.

Technosquare (http://www.technosquareinc.com/) does ECU flash programing on the 350Zs and is starting work on Titan ECUs. All Nissans in 2004 moved to the 8MB ECU and wideband O2 sensors.
The are products on the market in Japan for the 350Z to use the ODBII port to get info like engine temp, O2 readings, water temp, injector duty cycle, all the usual OBDII port scanning tool stuff, but they have little display units that you plug into the ODBII port and will display all these things on a little LCD.

I am trying to get more info and track down some of these products from the 350Z side since they will work on our Titans.

Just though you guys would like to know.

They may have both and I had looked at that before but came up with nothing due to the fact that I'm ignorant about such things. But the O2 sensors that are downstream of the cats are most definitely the narrow band 0-1V sensors since this is where I tied in a cheapo a/f gauge and it works. There are two more upstream of the cats that have more wires and also the service manual indicates that it is putting out 0-5V just like the widebands I have found so far. I think I remember reading that the ones upstream of the cats are used in the first 5 minutes until the cats and rear O2 sensors heat up. I'll have to dig again.

But hey, I can email/call technosquare and see what they are doing - somone to talk to!! Yea!!

I also ordered a mechanical fuel pressure gauge to mount outside so I can see what its doing. Have to figure out how to mount that thing for easy removal since I don't want to tool around town looking like Ricky the Rice Racer with a gauge mounted on the windshield valence.

Wow, that would be great. I am anxiously awaiting

There are several OBDII code readers that use either PC, Palm, or Pocket PC. A couple of the URL's are Below

Check them out they are pretty cool toys I mean tools

http://www.plxdevices.com awesome wideband!! I used one to tune my stg 4 wrx... one of the best on the market for a kick *** price... they're even cheaper if you buy from http://www.streetrays.com

confused... before reading this post, I thought a wideband would only be installed on the primary O2 sensor location
Now it sounds like you are trying to put it in the secondary o2's bung?

Someone educate me please...

Also, if what Speed-Freak is saying is accurate, then don't waste your money as you can tap in to the factory wide band if that's what they are, much in the same way that you tapped in to the secondary for your guage.

I don't think you would want to do very much engine management BASED on data gathered from the secondary O2s.
Your usable data is most likely going to come from the primaries.

Absolutely.

The best thing about it is the O2 sensors that output 0-5V are before the cats so you get a better reading of what's coming out of the combustion chamber. Here is the link that I posted a while back:
Air/Fuel meter or gauge

Thanks for the links. This one looks most promising since we do have the CAN style setup on our trucks. And if the Mapquest thing was correct, the place is only 10 miles or so from my house so I should be able to get some help, if needed. With the wideband capability in it, I could find out real quick if our vehicles are so equipped. I sent them an email and will most likely call tomorrow.

Thanks again for the help!

I was at Technosquare, since they wanted to abuse my 350Z. Yes, they are working on Titan programming, no they have no time tables. They are swampted with 2004 350Z stuff since Nissans move to the 8MB ECU destroyed all the work they had done on the previous 4MB ECU.

Bright side is that since they are all the same figuring one out means almost no differences between different vehicles. The Titan has them concerned though since the Big Tow and 4x4 models have more maps than a regular vehicle. Tow Mode and 4x4 modes get seperate maps. Takes time to decode everything.

I was telling the guys there that i wanted to use the factory wideband sensor when they told me that the new ECUs went to wideband, thats how I found out that the OBDII port can read it.

As far as looking it all up and seeing which sensors are where and which are used when is beyond me. All I got was that they are there.

As an aside Technosquare is about the only Nissan ECU tuner that seems to be worth anything. No other comapny does ECU tunning on the 350Z and all the aftermarket Forced Induction products use piggy-back or a combination of bigger injectors and add-on fuel controllers. I was also told that a couple companies developing F/I for the Titan have contacted Technosquare to do the engine managment, but no deals are set, but you all probably know of one company already, since they have proto-vehicles all over.

I should be heading back over there this week sometime with the Z so I will see if there is anymore info I can get about using the o2 sensors.

[the head]

Awesome. Thanks for the heads up.

Yah, that second one looks awesome to me also. For $140 it is a STEAL. I saw the option for "Change ECU" on one of their freeze-frame photos.. got me drooling.. I mean thinking... Wonder if you can change some other things with that option.
