NEW FILES ADDED!!
26 Dec 2012 - New files!! Schematic and board layout for the NGE controller Main Board, configurable for 1, 2, or 4 cylinders. Download free program to view, modify, and order printed circuit boards:

Files are in the projects section:

The IGBT Boards are still a work in progress. The main board is designed to output timing pulses for two or four cylinders. The 40 pin connectors (J3 and J4) are ribbon cable connections to the IGBT Boards. The 40 conductor cable is split into 2 each 20 conductor cables that then go to 2 IGBT boards. Each IGBT Board will be configurable as a 'cyl0', or 'cyl180', and also as HV ignition coil driver, or RF/TCC/BCC driver. Each IGBT Board also will have a prototyping area for alternate configurations, if desired. Perhaps I should sketch out the ribbon cable arrangement to show the fanout to the IGBT Boards..

Edit 27 Dec 2012:
I highly recommend gold plated machined pin/sockets for the MCU's. These come in 40 pin SIP strips, simply break off the length needed. (It is best to deepen the notch with a safety razor, then break)
