One EDIS
would be set to control the leading
plugs with a wasted spark, and the
second would control the trailing.
It promises to be a very robust
setup with multiple redundancies.
Don't forget that the trailing sparks must be distributed. Never fired at
the same time.
Because there will be an apex seal between the two spark plugs, and destroy
the engine.
Leading plugs in the lost spark situation, is no problem.
