Well then most of the components are already at spec :-)

Well, the key things I see here are:
1) All automotive ECU's I've looked at have had Commercial grade
components - and failure of these is very rare.
2) Most components I have selected (thus far) have Commercial and
occaisionally Industrial temperature ranges - can I select different
parts - perhaps. I have not found any which support Military grade - and
my read through Digi-Key and Jameco don't show any Military grade parts
(I haven't read both entire catalogs - but of what I have read - not a
single part).
3) Least important to me is any additional cost - and from what I've
seen thus far the difference between cost for Commercial to Industrial
is fairly trivial.
So, unless someone can point me to obtainable in qty 1 Mil spec parts I
will use Industrial where available and Commercial where I must...
All the electronic manufacturers' catalogs I have seen list CMOS parts as
meeting mil.spec.
