It has been a few years since I have done embedded
programming, but would be glad to partake in an effort
like this.

However, there is no need to re-invent the wheel. 
There are a few open-source DYI engine management
systems.  MegaSquirt being the most well known, and
others essentially being spin-offs of MegaSquirt.  The
better ones do all of the software in assembler so
they are more efficient.

Last I checked, the current MegaSquirt hardware will
handle both Batch and Bank fuel injection, as well as
simple spark control.  They have a new one that is not
yet out called Ultra MegaSquirt.  That one looks like
it will be able to do sequential fuel injection, as
well as individual spark control (for coil-on-plug
setup).  IIRC, it will also have support for forced
induction controls, knock sensor, fuel pump
control....  Actually, a bunch of inputs and outputs
that you can configure to do anything you want through
software.
