That falls into number three for me! Interesting, VERY interesting.

So, now the smart ars in me, why the hell doesn't the auto manufacturer use this principle?

Is this something the average ecomodder is doing?

On average, the fuel rail runs right next to the head... the fuel does get pretty heated, but the OE's don't expect the average owner to understand that it can't get too hot or it will stall, and keep track of fuel temperature as well as the barrage of fake gauges they already don't see on their daily commute, nor understand any of them.

Remember, there has been a steady push toward auto-pilot since the 50's. Adding another thing to make the driver think would be blasphemous.

Actually, it falls more into the vehicle customization point. The OE can't custom-tune every car to it's own specifics, so they use a basic setup that works well across the board. There is always room for improvement on an OE vehicle, which is why OBD-tuners are making such a killing.

Some newer diesels can "tune" up about 300 HP into their baseline without so much as turning a wrench.

The newer Hemi's have been proven to make 500+ with a few ECM mods and bigger injectors, and still get close to the same economy (within 10%, I think it was).

There's alot more to fuel economy than the OE's can really handle with mass tuning, so they develop something that "works" and "works well" (in the economical/relatively reliable sense), and they "roll with it". Pun intended.
