For a DOHC engine, the dizzy runns off either the exhaust cam.
It then 'distributes' spark to each spark plug lead, leading to each spark plug.
Within a dizzy is a rotor cap, which spins according to the possition and timing, which then provides spark to the plugs
You can increase or descrease timing by moving your dizzy a couple degrees.
Most import turbos are benefited by retarding timing a couple degrees to help with 96ron.
NA's usually benefit with a couple degrees of advanced timing.
