If anyone's having problems with the stock ignition coils, and doesn't realize that the stock ignitor is just a transistor array that switches the ground of the individual coils, this sentence might help you.
Yep, knowing how stuff works really helps a lot.

People have had problems with the stock ignitors due to not realizing the very short dwell times that need to be used with them, and how to figure out what dwell times should be used. I burned mine because the dwell time I had it set to at first was 6ms (tunerstudio default). Even the LS2 coils only need 4.5ms, and I believe I came across someone using a dwell of 2.3ms with the stock ignitor/coils without problems. Now that I know that, once I have everything running well on the LS2 coils, I plan to switch back to the stock ignition hardware and figure out settings that work for them, so others will be able to use them and not have to spring for the LS2 coils.
