let me see if i'm following -
a .2v allows more voltage/current to flow to the coil thus allowing the coil to operate at a higher current level. but what does that have to do with the ECU? the ECU is nothing but a fancy set of points. does the resistor only become a factor to the ECU when starting the car when current/voltage draw is higher? the box operates at 12 volts and i thought the voltage regulator kept that level steady? MY HEAD HURTS!

The box (ECU) is simply a more advanced "switch" to fire the coil..
The ballast resistor is not a factor in starting it is bypassed..
So the resistor & coil get a full 12V...

In the earlier days there was a 2-part ballast resistor that dropped the voltage to the box but later it was not needed..

Just my $0.02..
