Ignition System
 

I have a question about the ignition system of a RX-7. The ignition system of a 2nd gen 13B is solid state. Is there a eccentric shaft position sensor to control the ignition? I dont currently have one, are their two ingition boxes/coils for each rotor or primary/secondary spark plug. Do the the two spark plugs in the same rotor fire at the same time or slightly delayed?
