Wideband A/F Meter?

[Marc Lublin]

Does anyone know of a decent wideband Air Fuel meter for a good price. I know the Motec unit is a bit steep at $1200

Do you want air/fuel control or just a gauge/recording w/b unit? I have a w/b with digital monitor and recording capability that I am installing. My o/2 bungs will be here tomorrow. I have also found a few more that are similar made by different folks. Let me know and I will dig the links up and post them. ta

Marc. You might want to try asking motec directly in Australia. I have had a quick look at their website, but no prices are listed. I have a price list from Middleton Rally Team - they do some really high performance WRX tuning here in Australia. They list two items:

MOTEC AIR FUEL/LAMBDA METER #1 KIT 2095.60 Aus Dollars
MOTEC AIR FUEL/LAMBDA METER #2 KIT 1625.00 Aus Dollars

The Australian Dollar is worth about $0.55 US. You might be able to get better prices from motec directly, or at least find out what the difference is between the two. I know that a local guy Julian Edgar (www.autospeed.com editor) was working on a cheaper alternative, I believe using the same 5 wire Bosch as the motec uses. I've emailed him and will let you know if this is available. I think the Bosch sensor itself is only about 150 USD.. the rest is in the electronics.

Let us know what you decide on, as I wouldn't mind getting a reasonably priced AFR gauge if there is such a thing. A lot of motec's stuff seems very overpriced.

Here is a cheaper wideband sensor... can't vouch for it at all, just found it.. They seem to know their stuff pretty good, and youc could probably get out of it for 400 bucks or less... http://www.techedge.com.au/vehicle/wbo2/default.htm

Tony, I'm just talking about a meter/wideband sensor, not a unit to control A/F. If you could dig up some links that would be great. I did find this one http://www.rx7.com/cgi-local/3catalog.cgi?cat=12&part=6, but it's also expensive. On that page I think the only one worth getting is the bottom one.
Miles, If you go on the Motec site they list a bunch of dealers in the us. Most show Motec one at $1200.
Thanks

Thanks Sean, I had come across their site last night and then lost it and couldn't find it again. Have you used thier product?

FJO is great unit. it's easy to install and you can datalog to your labtop. i'm not sure but some supra guys are using wide to run their cars.

Marc, MilesB is talking about what I have. http://www.techedge.com.au/vehicle/wbo2/default.htm You have to get the sensor seperately. It is about $170 from partsrack online. Here are a few more: http://www.widebando2.com/ it looks like the same stuff Sean posted but different vendor. Another one : http://www.lambdaboy.com/ My sensor bungs were delayed and should be here Monday. I will let you know how it goes.

EDIT: Change the vendor for the sensor to http://catalog.thepartsbin.com/
JonB has got a spell on me for sure!!!!!!!!!!!!!!!!!!!!!!!!!!!
Please note they will have the sensor for a few days then be out of them for two weeks then have more. They are the cheapest and its the one all these monitors and som ecm's use.

 

[Miles B]

Tony.. definitely let us know how it goes. If it's good, I will get one of their DIY kits, build it myself, buy the sensor and have the whole thing for 250 US Dollars. Do you have access to another meter to compare it with?

Marc, yes the US price is 1200, but I think they are actually made over here in Australia. And since our currency recently died , it could be cheaper to get one shipped out from here. Eg if Motec sell them here for 1500 Australian, thats like 800 USD. I'm sure one of us Aussie guys would help arrange it for you, if it turned out that was the situation, and Motec don't want to ship overseas.

Here is another site I was given about the Tech Edge unit http://www.tragacs.com/wbo2.html Turns out it is based on a design by DIY EFI... now THAT is an impressive project.

Miles, I do have a car with SpeedPro/ F.A.S.T. ecm and w/b but I wasn't planning on comparing it right away. I do have a spare **** (4 total)and could compare them at the same time. Might not be a bad idea.

 

[Miles B]

Tony... any updates?

 

[1TONY1]

Ah sorry Miles, We talked about it on another post. My Aust. w/b has been installed since 11/23. That same day I went to a Mustang dyno and checked mine against their w/b. I had welded in an extra **** next to each front factory 02 so they were in similar locations. Best we could tell looking between inside the car and at the moniter they were within .1 of each other. Almost dead on each other. We have only recorded it one time so I don't have much experience with that yet. I did find that the air vents above the radio in my 96 are almost the exact size of the display. I have it pushed in there now with the wires coming out the front. I will be making a place for the wires to come through the back of the air duct and it will look almost factory. Mine is version 1.0, they have a 1.5 coming out that will do more....record rpm, record two other inputs and a few other features the 1.0 does not have. Over all I think it works great.

<FONT COLOR="Black">If you are feeling gutsy you can make your own wideband A/F meter. This is from the DIY EFI site. The description is:

DIY-WB O2 Project Readme File

Robert Rauscher, July 2001

This project is for the building of a wide band O2
measurement system. It utilizes a 5-wire NTK UEGO
sensor. The DIY-WB controller will measure AFR's from
10.0:1 through free air.

Sensor is from:

92-95 Honda Civic, 1.5L VTEC 5 wire 36531-P07-003. (~$250)

the project can be found at:

Have fun!

Tony,
thanks, sounds great. Unfortunately, the bike I wanted to use this to tune was just written off.

Craig,
I think the one Tony has comes from the same original design as the DIYEFI.. the company Tony bought it from sell kits to build yourself, or completed units for a little more. Sounds like a major bargain from the results..!

<FONT COLOR="Black">Miles - thanks for the Info. It looks like my project queue just got a little longer. I may just have to build one of these! I have to finish the radio failsafe for the Nitro burning monster truck, and the skid steer controls for the battle bot the kids and I are building first. This one could be cool to add to the project list. Thanks for the pointer.

MoTeC, and fjo are great, but consider this:
http://techedge.com.au/vehicle/wbo2/default.htm

I bought the pre-built unit, and for under $500, I have a WB that replicates chassi dyno data. It includes a RS232 output for data logging and a digital display. For the DIY person, I highly recommend this as a cost-effective solution.
