...a tad more info as you're winding down the search.
Chris, a friendly parts guy at a recycling yard (AAA Small
Car World, FT Worth TX) says he might have several of the
Mits coils. I gave him the part #'s and will here back from
him in a day or two. According to him, the Eclipse is the
same car as the Eagle Talon and Dodge Laser.

PS I guess I have never introduced myself...
I used to work in the 'gray market' auto import business in
the eighties. I designed and built the controlers to
interface oxygen sensors with whatever fuel system the car
had K-jet,L-jet,Motronic etc. 
It was a great job. Some of the more bizarre early
experiments:

Building a variable voltage supply (controlled by the O2
sensor)
for the electric fuel pump...Bad idea.

Disabling 4 evenly spaced injectors on a V12 for~30sec
during cold start
to use them as air pumps. Worked great, not sure about
consequences to the engine though...

Now I'm rebuilding Lucas electronics for Jags. It's not too
exciting,
but it has potential for growth.

Since I stumbled onto the diy_efi group I have started to
ask myself a lot of 'what if' questions
again! So I look forward to following this ION project and
will try to avoid the 'how many inches to a foot'
questions that someone mentioned.
