Fine - if you're going to design an ECU for aftermarket use, I'd at least
expect that you've benchmarked everything you can get your hands on.
There's a lot of history out there to be learned from, if one wants to take
the time (haven't I heard you say nearly the same thing?).

There isn't anything "pretty" about a properly-designed enclosure that
incorporates proper environmental and EMC protection, or a harness that uses
materials and parts that are proper for the job.  A well-built PCB assembly
isn't just "pretty" - a clean design is likely to be more reliable in the
field.  When I look at something like the PCM on my desk, I don't just see a
"pretty" module; I see a module that someone designed for the environment
that it's used in.

This isn't just a problem with the aftermarket guys - the motorcycle OEMs
are horrible in many of these same aspects.
