I understand that several F1 teams will be using very advanced electronic ignition this year.
Adrenaline Research

have produced an ignition system that uses a CDi system to trigger the spark to jump the plug gap and a radio/microwave channel induced 100A pulse to ride the spark.
It is supposed to be able to fire 22:1 air:fuel ratios and produce 3-5% more power at optimal ratios.
It was a bit pricey for my Grp1 RX7 at $50,000, but for 15-30bhp in F1 this is small beer.
Spoke to a radio ham/elec eng friend of mine, who said concept is OK, packaging would be the hard bit.
