8051 EFI

Paul Corner mentioned a home built EFI project: (complete quotation below)

What state of play are others at ?


Hi, Paul,
I have an application in mind for a custom ECU, myself.  I'm curious just 
_which_ '8051' you have chosen.  I have a so-far unused Dallas
"Speed It uP" (Dallas' own pun) DS80C320, which is, as it sounds, a fancy 
8032, but with a high clock speed and reduced clock-cycles per instruction.  
After a bit of (attempted!) rational thought, I have considered strongly 
using a Motorola processor (designed for the application), if not the 
(totally irrational?) Infineon AUDO TC1775 TriCore, which is also aimed at 
engine management (just plain 'heavy sand' - fun).

A "batch of boards", you wrote;  is this an idea for production?

What's your application?

Mike
