Thank you for the explanation...MSD does make some MSD Smart coils, and I will also look into those as well. I read a few reviews, and most were very good.
BTW, my Corvette C6 PWM controllers that you set me up with are working out great on both cars, however I am leaning on replacing the 160* thermostats with 180*. It seems that the engines could use the extra heat for moisture control, and less sludge problems.
