Air/Fuel for CIS/CIS-E

[rfkellner at snet.net (Rick Kellner)]

Timbo, I have a schematic and write-up for a DIY fuel enrichment module.
This is the module that adds resistance (and subsequently fuel) to the
coolant temp signal circuit only at the higher RPMs.  I had heard that
the circuit that simply adds enrichment at all RPMs tends to bog down at
low RPMs because it is too rich.  CIS-E only leans out at higher RPM and
that is why the one with an RPM set point is preferred.
I am not the author or designer however I did communicate with him a
little while back and there are some minor tweaks that can be updated.
If I clean up the old links and text is this something you would want to
post?
Maybe some EE students can make some enhancements by replacing the relay
with a transistor?

Rick.

I'm making a new technote for the site. an Air/Fuel adjusting guide,
and about o2 sensors. So - I know you so 8vs with a dwell, and 16vs
you measure the current to the DPR.

What I need are some pictures, and your permission to use them in my
technote.

I want a picture of a dwell meter - it's scale. I also need a pic of
the harness setup you use for the DPR thing.

--TIA - TIMBO!!
