WB O2 Kit / NB O2 emulator Datalogging


Recommended Posts

Check out this site they sell complete units or Kits that allow u to replace the 02 sensor with a WB one and also interface it to the ECu (Narrow Band emulation/output) it also allows you to datalog your A/F ratio's (Even to a Palm OS device!) Sounds awesome!

I want one :)

i don't think so:

 

"The sensor reads the partial pressure of gases in the exhaust and infers the AFR, rather than by measuring some magical AFR directly. This may be an issue on forced induction, and in particular, on turbo-charged engines.

 

AFRs will indicate richer than they are, causing you to run leaner than you think.

Lean AFR's will be richer (or less lean) than indicted. "

 

probably NOT a good idea.

...on that note, I got a little scared.  The lamdbaboy.com wide-band that I just got weeks ago also uses the NTK L1H1 sensor.  So I figured that I'd do some research.  This note on another Wide-Band site made me feel a bit better.

 

"The sensor responds to the partial pressure of oxygen. Excessive exhaust back pressure will affect sensor readings. This should not be a problem with any performance exhaust system. When used with a turbo, make sure the sensor is located downstream of the turbo."

There will be no problems running that WB OB unit.

 

The system uses the new LSU4 style O2 which is a pump cell type. This type of design is the new style of WB O2 sensors.

 

These sensors are stock issue for turbo Volvos, Porsches, VW's and many other newer cars.

The older style LH1 sensors where used for a particular Honda model. They will not be available readily soon.

do you already have it hooked up?/ an what do you think of it??  an hows the program to run it,. easy??  an are you using the palm.  i have a freind that has one on his awd talon,. but his just pluged in to the existing comp,. an reads an inputs on the safc.

I'll be honest, I have only tried it for a few miles and didn't use any of the datalogging stuff.  And I still haven't hard wired it in yet.  I don't really need it until I gather the last few parts for my next stage of upgrades, but maybe I'll get it wired up this weekend.  My new turbo just arrived today, so I might be distracted.

 

The Bad:  I don't really care for the DB9 connector used to connect the sensor to the box/display. I will probably replace it with something a bit more weather/stress proof.  The display/control box is large.  There's no way to integrate it into the interior for full time use.  I'll probably start with it mounted on the inside of the glove box so it's only visible when it's open. (the display box really is pretty ugly)

 

The Good:  It works, and is accurate from what I can tell in the minimal testing that I've done.  Price is the lowest that I found aside from building my own.  It's got an analog output for, well whatever, I plan to tap into it for a multi channel (home made) data-logging unit and/or perhaps some sort of cockpit display, even if it's just a few LEDs.  I figured as long as it has an analog ouput, I can have my way with the data it spews out.

The bosch WB 02 sensor is about 100 bucks.

 

You better jump on that price!!!

 

Around here (So California) Parts stores sell them for $699.00 or the local Honda dealership $499.00 ebay has them for $250.00 and www.fjoracing.com reps sell them for 199.00 if you buy their kit ( www.cyberauto.com ) but you may be thinking 4 band instead of 5 band.

 

Rumors about the Honda dealerships not selling only if you have a vin# for the O2 part number 36531-PO7-003

 

I don't know why on the link from http://www.techedge.com.au/vehicle/wbo2/default.htm

 

http://www.techedge.com.au/vehicle/wbo2/wbntk.htm (this one) says the sensor is for non-California vehicles and say nothing about the vtec motor which the sensor is designed for. The reason Honda looked into the 5 band sensor was to be able to stay ahead of the emissions regulations .

Here are some other links regarding information and other sources for this type of product

 

http://www.picotech.com/data.html

 

http://www.aces.edu/~gparmer/efi/temp/wb/guide.html

 

here is a link to a move for the FJO  O2 data logger and what they did to it to test its durability right click on the link and (save target as) it is in windows movie format

They use to be in the weapons development business but they dropped that side line (kinda scary)

In the link you refer to the 4 band sensor is not the sensor the after market data loggers are using and in that link states quote:(" A sensor in this list doesn't imply support for it with the WBo2 unit. ")

 

The sensor being used is the 5 band sensor. Which are being horded and or very expensive to say the least. But are available.

The one on WBo2 site is an LSU4 wideband sensor.

 

The expensive Honda sensors are the NTK L1H1 wideband.

 

The LSU4 sensors are used on a variety of vehicles stock.

 

In the future most WBo2's will be the LSU4 type so the L1H1 is going to be phased out on aftermarket A/F units.

I read that warning but I think any datalogging capacity for this car would be pretty cool so we wouldnt have to watch the gauges right away.  I think this could also be useful because you can have a WB to monitor how accurate the regular A/F (ie: Autometer) gauges are.  Anyway just some things to share..

Thanks for correcting me I thought that

was the home page

and didn't read

 

http://wbo2.com/default.htm

 

I guess there are to be more updates/upgrades I would like to see comparisons between the two sensors 4band VS the 5band I know the 5band has a greater sampling rate but just how great?

Tech Edge unit is a REAL nice unit.

 

I think the quality of O2's is just going to get better with time as everything. Most of the current L1H1 are excellent WB A/F's but again the sensor is getting expensive and hard to source so the aftermarkets are swaying towards the "new" type of sensors.

 

Either way WB are one kick tail tuning aid.

can you tell us exactly what cable (length) and parts you bought and if you would change any thing you ordered for a better install. Did you put your sensor in the stok location?

MetricMan, here's the info on lamdbaboy.com (Julian sells a unit with the NTK and a unit with the Bosch sensor.)  

{

 Sensor type:  5 wire NTK UEGO L1H1

 Range:  8 to 25 AFR

 Accuracy:  1% at 14.7 AFR, 2% full scale

 Response: 0.1 seconds

 Air Calibration: Yes

}

 

{

 Sensor type:  5 wire Bosch  LSU4 wide band

 Range:  10.5  to 25 AFR

 Accuracy:  2% at 14.7 AFR, 2% full scale

 Response: 0.2 seconds

 Air Calibration: Yes

}

 

I'm going to guess that the response times quoted are based on the sampling rate available from the sensor, so it should be comparable for any units using these same sensors.  Julian said that if properly cared for, the NTK sensor should last 100,000 miles so I'm not considering the sensor replacement cost an issue.

 

For datalogging, I'm planning to capture three primary values at first; MAP sensor, A/F ratio, and RPM.  The only tricky one may be the RPM.  For that I'll use either some sort of inductive pickup and a filter circuit or try to use the hall sensor signal once I get the magnets and pikup installed.  My datalogger will just be a Basic Stamp 2 hooked to a laptop or PDA because that's what I have laying around.
