Ignition Dwell and ignition booster

is there a topic on how to optimize ignition dwell? and tuning a car with a ignition booster/voltage boost on the ignition coils.

What engine? What ECU? What is the ignition system? On any of the modern ignition systems (individual coil per cylinder) usually you just input the coil dwell information from the manufacturer and you are done. If the coils aren't powerful enough you buy aftermarket coils and then input the coil info into the ECU.

Ignition boosters are basically a 90s thing.
