Messing with the ignition and my scope
 

Took some caps.

What I did was take the spark pickup for my auto
tester and hook that into the scope. Have zero idea
what the actual conversion is and didn't take the time
to set up the scope just perfect. This was more of a
"can I do it" experiment.

Looks interesting enough. Next is to hook up the O2 sensor
and use that picup to synch to #1.
