Hi Doug,
I don't know if you can program your oscilloscope to work like an
auto diagnostic tool, but if you could program the ignition system to
show all the spark plugs on the screen at once, so that you could do
balance tests, and then other things show up like a sore thumb, like bad
ignition wires to cross firing between cylinders for a couple, saving
hours of testing: http://www.----------.com/oscilloscopeIgnitionTest.jpg

Don't think it's possible. The scope is only two channel and I've only
got one clamp on pickup.
But I can store the waveforms in memory and do that on the computer.
Just not real-time.
On the other hand I have seen PC based testers out there for reasonable
costs. Picotech.com makes one but it doesn't look like it does multiple
spark plugs like a Sun or SnapOn analizer does.
