Why not get involved in the EFI332 project?? The basic CPU board will 
be very flexible - 16 timer lines, 16 general I/O lines and a serial 
bus for A/D, etc. It has been suggested in the past that you don't 
need this much power for EFI - you don't for a basic system. However the 
actual cost difference between a 68332 system and a HC11 system is 
not that much, especially if you're considering buying a commercial 
development system. You also would have the advantage of using all 
the work that anyone else contributed to the project.

NOTE: I know the HC11 is a great little device: I've used it for a
number of years and was planning on building an EFI system with it
until this project was born. 

If we get more people actively working on the efi332 project we could
all build a cheap EFI system on a quality PCB with ignition,
sequential injection, traction control, data logging, etc.

When the basic system is finalised it should actually be *easier* to 
program the EFI332 than your average 8 bit micro (IMHO).
