Hey.. before I started my project I saw yours over there at mini-itx.com.. nice work! The Ikea keybox was a great idea and I tried to find something similar for my endeavor.. but since the dimensions were different I was unable to find anything prefab in the correct size, so I just built my own enclosure. Oh well.

Anyway, good job!

Peace!

Very cheap, if you have a compatible car ("VWs, Audis, SEATs and Skodas").

There was an article in Circuit Cellar Ink about an ODBII interface; it looked like it wouldn't cost much to build. October 2000, issue 123. "Routine Checkup—An Automotive Diagnostic Scan, by Dan Harrison"
You can buy the interface, and/or d/l the software: http://www.ghg.net/dharrison/
If you can find the article and build your own, the .s19 file for programming the micro is at: ftp://ftp.circuitcellar.com/pub/Circ...arrison123.ZIP

I just can't figure out where the ODB interface port is on the one-barrel Holley 1904 carb on the 223 Ford six.

I checked the website and couldn't find active links for the article. I then checked out the zip file and boy is it small. I'm guessing that this is only for the ISO9141 interface and not the VPW or PWM interfaces.

Do you or anyone else have a copy of the schematic in this artical?
