Hey Guys,
As some of you that have had the flex fuel sensor(fuel compensator) take a vacation know what kind of price to replace them is, I stumbled upon a flex fuel replicator on E-bay. It's made by www.tandselectronics.com. 150 bucks. The drawback is that you can only run regular gas w/10% ethanol and the higher octanes. I ordered one and should have it this week. Sure beats paying 600 bucks for one. Check out the website. It will explain how it works. I'm hoping it's money well spent.
Many of the 'smart guys' in Washington DC say that adding flex-fuel capability to our fleet mix would cost very little. I wonder if they know something that just isn't so? If a replacement is as high priced as I have observed, why do they think it is so cheap to add to every car? I have no problem with ethanol or methanol as part of our fuel source, but most FF vehicles I have heard of don't use anything but regular pump gas as that is all that is available. Here, FFVs can use the diamond lanes - even if they are not using any ethanol in their tank.
So, the frequency adjusts in proportion to the ethanol makeup. What does the pulse width indicate? I thought that there was a FF gauge being developed that used the transparency of the fuel as its indicator of ratio. Wonder if it was a change in diffraction of a beam of light through the fuel as if flowed by the sensor.

What they probably mean is that it would cost very little for manufacturers to implement more flex-fuel technology. Which in the auto industry hardly ever translates into less cost for the consumer. Especially when it comes to OEM pricing of parts. Like for example, Ford asking $31.00 for a friggin' thermostat for my 4.0 Ranger. Utterly ridiculous. And it's not like a t-stat is "new" technology, either.
I bet an OEM flex fuel sensor costs Ford (Motorcraft?) no more than $75.00 to manufacture. But then they turn around and sell it to us for $400.
