Haltech's box is supposed to be easy to program, but of course it wouldn't be 
OEM plug compatible with anything.  It's also meant to drive pulsed injectors,
and so wouldn't be useful on an Audi with K-Jetronic.  I've been considering
this box for a motor I want to build in a z-car.

Well, you have to understand the physics of the problem space that
you're working with in order to build real-time software.  Also
have knowledge of hardware and electronics.  Software or "hacker"
skills don't come into play until one tries to a) cram the always
much-too-large program into the always very limited ROM; or b) figure
out how to instrument/debug the thing to as to be able to diagnose
and fix it, without breaking either time or space constraints.
