Who has made the DIY WBo2 Kit?
 

What do I do with j9&j10? This is the CalR connection?

I'm in the process of testing this WB and am confused on what this is.

Re:Who has made the DIY WBo2 Kit?
 

Update. I fiqured it out. I have the kit and installed just a matter of tuning with it to see it it works!

Hopefully it does because that means this WBo2 cost me 30 bucks and a few hours of assembly and testing!

Re:Who has made the DIY WBo2 Kit?
 

i just completed the kit as well it doesnt work as of right now but i went half way through the testing. Ive been busy lately so ill get back to it this week. wat does j9 j10 really do? it's used to test i know but how exactly? and how many of the "extra" resisitors did u add?

Re:Who has made the DIY WBo2 Kit?
 

what are you using for display? I have one the board is completed, but no display or o2 sensor yet

Re:Who has made the DIY WBo2 Kit?
 

j9 and j10 is only used in testing (as far as I know)

works good so far. I just have it in the car, haven't done any tuning with it. For extra resistors, I think I added 2 330~ and 2 200k~. Not to sure. I can check if your still fuzzy.

For display, Right now it's jsut my DVM, but I might buy the datalogger that is linked on the site. (Hopefully I can link it to work with rpms or boost or something to reference it against)

Re:Who has made the DIY WBo2 Kit?
 

so it was only $30 total cost for your wideband?

is that 100% everything for it?

Re:Who has made the DIY WBo2 Kit?
 

I'm still undecided on what to do, should I just just buy a professional wideband,$300 plus, I got the money, or should I complete this DIY kit, :-\ I'm tempted on the plx m300, or so $315 shipped. I dont know what to do. help me decide.

Re:Who has made the DIY WBo2 Kit?
 

Almost, By the time the kit came to me it was 30 dollars. Then wires and a project box. Total 45 dollars tops. The sensor came with my Manifold when I bought it from the junk yard. I just took it out of the manifold and kept it thinking I know someone that could use an OBD1 o2 sensor. Then I learned it was a wideband.

Re:Who has made the DIY WBo2 Kit?
 

cool thanks for the info bumblezc, im just going to use a volt meter and have my friend log the data on a notepad.

honestly i wouldnt have bought this kit, i only bought it because i had an 02 sensor laying around.

Re:Who has made the DIY WBo2 Kit?
 

do you have the link and pert number for that DIY wideband...i want to make my own..how hard is it you think? on a scale from1-10?

Re:Who has made the DIY WBo2 Kit?
 

on a scale from one to ten id say 5.

Re:Who has made the DIY WBo2 Kit?
 

I didn't find it hard at all. if you have basic soldiering skills you'll be fine. YOu just need a fine tip soldiering pen.
My hardest part is tryng to make everything look neat and transferable to other cars. I just used trailer connector and am going to mount it in a nice solid box.

It's all there.

Re:Who has made the DIY WBo2 Kit?
 

I'm still looking for a display. If anyone knows of an inexpensive digital voltage gauge that would be great. The best I found was a 2"x1" 3 digit diplay but it was 69 dollars. I can use a multimeter for that price. I got mine cheap so I might try to disassemble it and mount it all in on unit.

A I have a few others around so it will be no loss

Re:Who has made the DIY WBo2 Kit?
 

looks likeill be getting that kit.. ;)

Re:Who has made the DIY WBo2 Kit?
 

hey bumble where are you getting the power source from? theres two seperate circuits one for the heater and one for the wb. and so u really did use 4 extra resistors? thanks man

Re:Who has made the DIY WBo2 Kit?
 

My power is coming off of my radio ACC wire. I just spliced into it. I'm going to switch it to another source. Not that the radio isn't a good source it's just that I have a turbo timer and I want to power the heater while the car stays running. That way the heater for the o2 sensor stays on and that way I don't ruin the sensor.

As for powering both circuts. I put my 12volt in to the heater first(j3)and then from the same hole sent a wire to the Uego power(j11) So they actual are on the same source.

I added 5 resistors in total. Exact value I cant remeber. My kit didn't come with extra so I had to use some I had. I can't tell the color so I can't tell you the resitance the are because I insolated my board with some hot glue to protect the wires. My best guess is I used 2 330 ohms and I think 3 200 ohms. Not to sure. It's a hit and miss trial. Just make sure the car is running when your testing it because mine wasn't and I couldn't get the sensor to warm up because of the lower voltage. Mine now warms up in about 45sec.

I'll answer any other questions if you have them. This thing works great!!!

Re:Who has made the DIY WBo2 Kit?
 

hey so you turn the heater circuit on first then do u wait for the LED to come on and then unplug the heater and plug the wb circuit? sorry for these questions. I bought the kit from bamboo without papers just parts.

Re:Who has made the DIY WBo2 Kit?
 

No, The heater must stay on all the time. The uego circut automatically turns on once the heater is up to temp. That why while it it heating the output voltage is 2.5 and then once it's heated it can fuction properly.

If the heater is not active while the car is running it will ruin your sensor if it is in there too long.

goto www.diy-wb.com he has all the assembley nots there. Read them carefully to ensure you don't ruin your sensor.

and no prob with the questions I'm glad to help iut!

Re:Who has made the DIY WBo2 Kit?
 

Can you run datalogging with this WB02 on Uberdata and also I have an HX Wideband and I was wondering if it would work for this app or not.

Re:Who has made the DIY WBo2 Kit?
 

Not a clue. You can datalog this wideband but no one sells a specific kit for it. Remeber, this is a bare bones circut board. One the DIY site he has a link to a device you can use to sent the voltage read out to you computer. If you get something working let me know!

Also what is the HX Wideband, is that the sensor, Only a VX 5 wire sensor will work.

Re:Who has made the DIY WBo2 Kit?
 

The HX has 2 sensors a Primary 5 wire wideband and a seconday 4 wire. I was told that it would work but I was wondering since I have not converted to OBDI yet and my ECU is still using this O2 then can I piggy back the $30 dollar wideband onto it and use a DVM to monitor while using the factory warming and all of that or do I have to convert the O2 all the way over to receive any useable data. Also does anyone have a diagram of what all o fthe wires are for on the O2 sensor?

Re:Who has made the DIY WBo2 Kit?
 

I built the kit last year and it's been sitting on my desk untested ever since. I couldn't make heads or tails of what all the "testing" crap was about so I just put it aside and forgot all about it.

And I believe you can datalog with it and uberdata. They were saying on the uberdata site to set it as a Tech Edge V1. Not sure if you need the other parts, or just hook it up where the DVM goes?

Why did you have to add other resistors? Mine came with extra, not sure why though.

Can you post pictures of your setup? Sometime this week I think i'll try and get mine going again.

Reply to Stan:
Placing the resitors in Parallel with R4 allows more current to flow through them because there is more paths for it to travel. Do it one at a time to ensure not to burn out the sensor.

Tesing only took me about 15-20min. not bad, just follow the instructions.

I'm using TE on an obd0 car so datalogging is not available.

I tune my friend 94 b16 so I'll try to get Datalooging on his car to see if it works.

Reply to Civicnar:
There is a sechematic for the sensor at www.diy-wb.com.
I dont know if you can take the values directly from th o2 sensor. I would believe you would have to take it from the uego controller which would be you ECU. If you want to run a piggyback and not go to obd1(adviced!), you might be able to spice 5 more wire to your circut.

Re:Who has made the DIY WBo2 Kit?
 

What I don't understand is what i'm testing for after placing the resistors in line to heat up the sensor. Do I messure something, or hold it and wait for it to burn me. ;)

Re:Who has made the DIY WBo2 Kit?
 

It will burn before it comes to temp!!! Trust me!!

After completing the initial testing(find instructions on the diy site) Hook up the sensor and leave it in the free air. Start the car and time how long it takes for the LED to come on. If it take more then 1min turn off the car and add a resistor parallel with R4(One end to one, the other to the other), Start the car again and timethe warm up again, do this until the warmup take 45sec to 1min
