Ignition upgrade to full coil system

Did you check the MegaJolt box I mentioned? There is much info about ignitions on the megasquirt site. I don't think the $3K system above would give any better spark than a distributorless system like the Ford EDIS or the (better) GM LS truck coils. Both are popular w/ megasquirters. There is a youtube videos by a megasquirt originator showing the spark from an LS coil. I wouldn't want to touch it.
