Fuel Enrichment Device





I've been studying the Bentley manual, and the EC article on the Techtonics
Tuning CIS-E fuel enrichment device.  I'm more than 90% of the way into 
reverse engineering it.  (I'm an engineer by trade, so I feel qualified
in using such statements :-) )  What I've got left to learn is whether or
not the cold running enrichment is put on a duty cycle by the OX sensor
control module, which sends the signals to the control pressure regulator.
If it is, I believe that I can beat it by doing my own timed cycle, which
would reset the systems' duty cycle.  Well, I don't even know if it's 
going to be a problem yet.  I can you this though, the TT module doesn't
address it if it is an issue. 

Anyway, if I'm successful, and I can assemble some for a reasonable cost,
would any of you be interested?  I'm thinking that I could do an adjustable
version for not much more, but I'd have to make sure the potentiometer I
used was precise and stable.  I can tell you though that it wouldn't be 
worth a $100 more. :-)

I may just publish the specifications on my web site, whenever THAT becomes
a reality.
