Before I arrived, other researchers in our thermo labs had experimented
with various methods of measuring ion-gap voltage by measuring the secondary
voltage directly. They got no-where. The spike was enough to zap any
protection devices that they had available at the time. I'm not going to
bother trying - instead I plan to use one dual fire coil per cylinder
with my detection circuit on the unused secondary output.

I've got some Delco and Ford (??) dual coils handy.
