I'm interested in just the same things.  I've assumed assembler the
level I will have to work at and am learning standard PC stuff on the
basis that the concepts will be the same.  (I am a mechanical engineer)
I have not been able to contact Mr Arwood who has his WWW page showing
EEC interest despite several attempts and no repy from postmaster at his
provider.
At the moment I have an EECIV out on the bench with lots of wires
attached and have bought a cheap scope, a soldering iron and finished my
first project to build a EPROM programmer and a card in my PC to run it.

I,ve programmed my PC (via the eprom card) to give some sort of spark
input signal at variable speed which seems to satisfy the EEC as it
starts the fuel pump ( a LED on the bench ) when presented with it.

Now progress has slowed down some since I havent been able to work out
the CPU and hence pinout to begin some form of diagram.
