Interesting read on Ls1 and Ls2 coils
In an effort to learn more about the LS1 CNP stuff.... and how I might can retro-fit this onto my GN.... I ran across a good read....
Check it out. A quote from the article: "These LS2 coils are incredible. Even compared to the LS1 coil, these are just crushers! On the LS1 coil there is around 40 milliamps of peak secondary current with 5 milliseconds of dwell time. On the LS2/truck coil (AC Delco D585), there is 120 milliamps!" SWEET! Megasquirt Sequencer Here is a video of someone testing the LS2 coils and the "Yukon" coils.... LS2 coil test Very Impressive.

Yukon coils have issues (based on what the F-body guys tell me) The "square" truck coils have had the best success among the hot-rod F-Body guys.
The stock LS1 coils have a lot of 'zap' in their own right. Bob
