Hi,

I'm currently working on such a system.  Injectors are available from 
Siemens or Servojet here in the US.  My electronics are based on a 16 bit 
processor, and I can handle up to eight injectors, four ignition coils, 
drive by wire, transmission control, EGR control, exhaust temperature or 
oxygen sensor feedback and catalyst monitoring function.

Currently we are finishing hardware prototype manufacturing, and software 
design will start soon.

The only off the shelf system I know of that is suitable for your needs 
is probably the MOTEC system, but I have no personal experience with it. 
You can find their distributors on the internet.

If you are interested in my system please contact me directly at:
kleenair at ix.netcom.com

We will consider developing custom software for your application if there 
is some funding available.
