RE: Scott & injectors was Re: voltage dropping... dropping...

Oh, Dan Bubb is building a wideband oxygen sensor. His plans call for either
a custom-etched PC board or a bread board. Going with the PC board seems to
be a slight challenge, but it would make for a much tidier final product. I
am hoping that you could pitch in and help him with this. Wideband O2 like
the Holy Grail motor tuning!
