I have a friend that just bought a 2004 GMC 2500 diesel pickup.  The engine controller uses a 32-bit microprocessor, and they use that as a selling point.  When I first heard that I thought man, throwing a spark and a squirt of fuel in a cylinder is getting more complex nowadays.  I'm sure that the new 2005 emissions regulations in the US have something to do with that.

Regards,
Bob
