DIY Fuel Enrichment Device, now hosted for everyone

[rfkellner at snet.net (Rick Kellner)]

Dan, it is nice to be able to talk to the author and complement him on
an elegant straight forward design.  It is a little more sophisticated
that a relay and a 1k resistor that sells for $125.  It is also nice to
be able to ask some questions too!
I like the ability to set the RPM level when the enrichment kicks in,
apparently adding enrichment at low RPMs caused more problems than
benefits of adding it at high RPMs.  It is only lean at the higher RPMs.
 
Now, some questions.  Did you find the switches with the resistors in
parallel offered much of a change after 1,100 ohms?  Do you remember the
range of resistance the stock temp sensor produced?  Does it eventually
go (or approach) zero when hot?
Thanks, Rick.

I've seen this before, because, well, I invented it... probably in 1998
or
so.  Amazed to see it is still cirulating around.  A hard drive crash
years ago caused me to loose the original plans and graphics. I think I
even still have the original unit around somewhere, but I no longer have
the 16v.  

Anyway, yeah, it worked fine.  Tech America went out of business five
years ago or so, so the links won't work, but as you said, the parts are
all pretty common, Radioshack should be able to get them all, except the
LM2907N-8, which digikey.com stocks.

BTW, with very little modification, you could use this circuit to build
a
shift light for drag racing or whatever.
