A recent example would be my friend John Gilkison's new non-hybrid Civic which is getting 11-mpg better than EPA rating,and he's done nothing at all to the car.That's about a 34% 'improvement.'

*Sigh*

Stock ECUs have very good noise filtering from the factory. I have worked with electronics and eletrical systems for many years, I am not convinced any more noise filtering throughout the car system would yield a measureable difference.

Yeah what would be inside one of these things? A capacitor possibly?

And I am curious what those 3 LEDs might indicate - The gadget is only connected to battery and GND through the adapter plug. And what kind of filtering can it provide, when the wires go round and round the car (the adapter is fed through the ignition switch) before getting connected to the ECU? (I doubt whether it is directly or through a distribution panel)

In lighter vein, they should include a vibrator and a rechargeable battery set inside.

Two things are happening when you use the "Probe" that help efficiency. One, your wallet is lighter so the car is easier to accelerate and two, you are driving slower because you are watching the blinky lights on the shaft and wondering why you don't go out more often with the guys for daiquiris.

I sent an email to Hammacher Schlemmer asking if they provided Snake Oil with the fuel economy booster and they replied with a link to the site below which boast of a 25% increase!!!!Which proves that computers won't reject ones and zeros no matter how silly the claims are.

Their site makes it sound like a big capacitor. I love that they call the ECU the "Electrical Control Unit" ... Engine Control Unit. Brilliant. But they sponsor a race, car, so it must work.

Good find, Phil. Enjoyed reading the group's feedback.

Here's the link to the lab results.
