Hi Bert,
If you hook an oscilloscope up to the SAW output on your EDIS you should see a 0-5v square wave that changes with RPM. I had the waves, but they were going negative, so still didn’t work. Here’s my photos of the scope- the lines should have been going up not down like they were. I haven’t actually put the scope back on, but my timing light now shows the same advance as the computer says- it didn’t move before.
