Hi David

Use the Automotive preset for ignition, secondary, plug lead to get you started. The thing about pencil coils is that the field strength varys a bit from type to type. This is one reason we didn't do a preset for this probe but we may revise this before long as we get data on a few more coil types.
If no joy with the above preset, remember the probe will be picking up approx 100-200mV so set the DC scale to +/- 200mV or thereabouts. You can set a trigger to stabilise the waveform. At idle, 1mS/div should give a detailed picture of a single full ignition waveform. 20mS/div will show hopefully 2 events i.e a full engine cycle taking approx 160mS on a 4 cylinder.

See how you get on and get back to me if not sure about anything.
