Peter,
I would argue, that we have seen am inprovement in fuel economy. If I
were to drive a little slower, say at 65 or 70 mph, my MPG would be
about 14 to 14.5mpg. It seems I am always running late so I drive 80mph
:-) 14 to 14.5 is great for a 1 ton 4x4, powered by a 454cid engine.
The 14 to 14.5 isn't a guess, either. I was getting that before I
started leaving late for work.

To drag this topic kicking and screaming back towards
the list topic, as
many engines over the past 10 for 15 years have used computerised engine
management systems, why have we not seen much improvement in specific fuel
consumption? I would have thought that the systems would be able to run
the engine at optimum mixture and thus give a significant improvement in
economy.
What processors have been used in these systems over the years?
