[Shotimes] (OT) SHO replacement

[James F. Ryan III]

The Cadillac V-8-6-4 system was introduced the same year as the IBM-PC -
1981, and was used for that year only.  The "computers" in cars of the late
70s and early 80s weren't called OBD-I, that didn't start until 1982.  If
the brand new IBM-PC had 640kB of RAM and a 4.77MHz 8088 I can only guess
that the "computers" in the cars at that time were 1/10 of that.

My friend Lou's father bought a Caddy in 1981 with the V-8-6-4 and he loved
it.  He was so proud of it and drove it for many years without problems.  I
did a search on the internet and it seems its reliability was pot-luck and
the SOP was to disable the system and just let the engine be a V-8.

It's easy to look back in hindsight, 25 years ago, and say the Cadillac
system was a piece of junk.  I applaud them for their vision and the
engineering effort.  Who knows, if Cadillac hadn't offered the system in
1981 maybe Daimler wouldn't have been inspired.

When I did the search, I also learned 2 other things.  1 - The V-8-6-4
system wasn't designed by Cadillac it was designed by Eaton.  2 - This
wasn't Caddy's first foray into this area, in the 1930's they offered a
similar system on their V-16.  The system could shut off an entire bank,
effectively making a straight-8, and it supposedly worked well.
