I would actually have to say that a large share of the power lies in the
40channel ADC scheme.  Absolutely great thinking...

Also: just as response.
This is not going to be designed on a per person kind of thing.  It will be
designed such that it takes care of the critical elements, and some of the
hi-tech stuff that's mostly stuck in research (ala ION sense).  It will not
be "Hey can I get a light to flash above 2000rpm?" if you want that kind of
functionality you will have to program it in (or find someone to program it
for you), it's really that simple.

I'm of the opinion that the complexity of such an engine controller is far
above using a straight procedural programming approach, and so I think that
a RTOS (Real Time Operating System) should be utilised to provide access to
the processing power available, this will hopefully make programming small
items (like shift lights etc) as simple as programming a PIC chip (maybe
even easier with the use of C).

I'll check up on whether I can easily get some web space so that a central
repository for ideas can be setup :)
I'm not sure exactly what (hardware)development environment would be best to
use.  I've got the most familiarity with Protel99SE, however I'm sure others
have other favourites.  Ideas about this would be good as well.
