I was not able to find that in any archive searches.  It may still show =
up in archive.org at some point, but for now it's gone, unless someone =
has a copy.

The file http://diy-efi.org/diy_efi/projects/pw_meter/pw_meter.jpg seems =
to be missing. The other two come through fine. Has anyone got a copy of =
the jpeg schenatic?

Something like this?

http://diy-efi.org/diy_efi/projects/pw_meter/

I've seen a number of web sites with instructions on making an LED =
display air/fuel ratio meter using the O2 sensor signal. Does anyone =
know of any information on making a similar meter for measuring injector =
duty cycle?
I've seen a couple of meters like this available for sale, but never any =
information or instructions on making your own.
