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.

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.

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.

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. ;)

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
