DIY-WB... It's alive...

[Mark S. Riley]

Got the board finished and mounted in the box to the lid like Bob R did. Put
the terminal strip on the top side of the lid. Got everything hooked up and
it heated but voltage stayed at 2.48 volt. Took it back apart and I put the
led in backwards and had one of the leads on capacitor C7 touching the trace
crossing under it. Not quite the way it's supposed to be. Repaired those
goofs and it works!! Clean air voltage is 3.98 and sticking it in the end of
the tail pipe on my Escort shows voltages down to 2.2 volt just patting the
gas pedal. Now have to put a bung in front of the cat to get more accurate
part throttle readings. Am going to make a two bung pipe kinda like Bruce's
so I can check it against Horiba driving around. Later, Mark
