Hello Paul & Group,
Mazda tuners are using this ignition booster. Manufacturer claim  that
it does multiple sparks and has higher energy, and users seem to agree
on performance gains.

I have no idea how they do it. Maybe a place for some reverse
engineering ;)

USC is on your neighborhood Paul? right? ;)

Cheers, Petri

Or if they do it :)

USC is about 80 miles away.

BTW if you want to take a vacation I can put you
up for a week next winter :) The beach is 100 meters
away. It gets cold in Finland right ? :)
