This one has 8 channels of 10 bit A to D and can be programed
with no programer. Send the code from your PC through a serial port
to the flash memory in the chip. $11 bucks from DigiKey.
Heck at that price you can afford two. Only 35 instructions
to learn or you can program it in compiled BASIC with
8K memory locations to store the code. Way more than enough
for an EFIS. Compiled BASIC would be plenty fast enough for an EFIS.

Heck one could knock out an EFIS program written in BASIC
in a couple of days with this chip. I am tempted.

Just for my 2 cents worth, the PIC18Cxxx processors can be programmed
in C and Microchip offers a time-limited C compiler that integrates
into their IDE.  It's pretty nice, and you can always set your clock
back ;-)  They also have the FLASH versions if you don't want to deal
with EPROM eraser, but it looks like it will still be a few months
before they are in full production and available from places like
Digikey.  The PIC18's have a lot of PWM outputs for motor control as
well.

Mike Harrington just got two 16F877 flash chips. I think the smaller versions
have been around for quite awhile. I don't like C.
