It uses a MegaSquirt-II CPU to run spark and fuel and an MS-I CPU to drive lots of general-purpose IO. It also has add-on boards to support 4 coils, 4 low-impedance injectors, one EGT, two VR sensors and a few other goodies. With any luck this will be on my car in a few weeks.
The other project I'm playing with (I refer to it as "MSII on steroids") uses a Fairchild MC9S12X CPU in place of the Megasquirt II - with gobs more speed (40 MHz) Flash and RAM but running MSII/Extra code. Why? The added memory will let me run substantially larger table sizes, and the speed and 128-pin packaging means I can support as many features and IO as I need. This is a ways off though, so far I've only been able to play with the code on an eval board.
I may also try out a straight MS2/Extra system in on my car in the coming months.

Great to hear your experimenting with MS and developing your own ideas..that's what it's all about
If you get the oportunity post up a couple of pics of your prototype boards, and a few thoughts on where your going with it...
