Contrary to what you see on the web you can't elminate the ballast resistor unless you get a coil that does not require the ballast and if you do that you can elminate it with the mopar ECU too.
Are you serious or being sarcastic? Say I used an MSD 6A box, would that negate the need for the resistor and ECU? Or does the box simply amplify the signal that's sent out by the ECU?
