Been doing a lot of internet scrounging on how to put together a DIY wideband O2 reader/display. The most useful stuff I have seen recommended coming here for help.

I would really like to put one together a WBo2 as a project for my son and I. The site I eventually found (Welcome to diy_efi/efi332) had a parts list, but no schematic. There was a link to buy the PCB but the link was broken, and the email was unanswered... An archive note on that site was what led me here.

After searching your archives, I think I have a pretty good picture/idea of what happened in the past here when a DIY WB project was born. I'm sensitive to and bummed that the public domain gets taken advantage of a by a few...I've seen it happen on other sites as well.

With that said, I decided to register here and hoped that you'd be willing to help a Camaro brother out!

Does anyone here know of a source for the PCB or the schematic for this? Thanks, Scott

 

Damn, I had like 3 or 4 of the original DIY WB PCBs. Think I just threw them out.

 

Sounds about like my luck...

FWIW - The real issue with the DIY WB is the price of the Honda sensor.

Back in '01 the sensor could still be had for ~$100 brand new; last I checked
the same piece had risen to ~$400+.

Unless you have a source for the part at a reasonable price, there is (alas)
not much point in pursuing the DIY project. Which is a shame, since it was
such a magnificent idea. Mine's still running 5 years later...

 

Hey, I found those 3 extra DIY WB PCBs I had lying around. Guess my packrat mentality is still alive and well!

You're welcome to them, just send me an email offline if still interested.

 

I have a couple PCBs, send me an email.
