Hi All,

I'd like to build something that can pick up the high tension spark
impulses in a 6 cylinder engine that plugs into a laptop so that I can
record them. Then some way to analyze where a periodic 'misfire' is
ocurring. Any way or know method of doing this?

Thanks,
Jim

How about starting with a magnetic pickup unit from an ignition timing
light?
