Piston Slap: Decomposition of the Fuel Composition Sensor?

Flex Fuel. I see it more and more. From what I’ve heard, this mainly means the vehicle has a fuel system that alcohol wouldn’t eat up. (Mainly, yes. — SM)

So here’s my question: do the more recent models of these vehicles have the ability to sense what level of alcohol is in the fuel lines and adjust the engine accordingly, to make best advantage of whatever current gasoline/alcohol or alcohol/gasoline mixture is entering the engine?

Meanwhile, Back At The Farm: Ford Promises Flex-Fuel Bumper Crop

As TTAC readers well know: There is a huge E85 flex-fuel loophole in the new federal fuel economy CAFE standards. Ford will drive right through that barn door-sized hole.

By the end of this year, Ford wants to deliver 370,000 flex fuel vehicles, a number which they can trade against fuel oinkers. Let’s review: A flex-fuel vehicle is one that is capable of running on E-85. But it doesn’t have to. It can also run on straight gas. Or on any mixture of the two fuels. As long as it’s E85 capable, it counts at least for a Peppermint White Chocolate Mocha at the DC CAFE.
