ECO OBD2 Eco chip, fuel saver chip, chip tuner fuel saver They say 30 day money back guarantee, but when I contacted them they wanted pictures of the product and packaging before proceeding!

This "Eco chip” was brought to my attention via Amazon. I was searching for something and at the bottom of the page, Amazon had THIS product. It "pitched” that by simply plugging it into your car, it would "scan” your cars fuel consumption, and (somehow) reset your cars computer so that it would use LESS gas.

Well this chip did NOT do such miraculous feats and my cars estimated MPG (miles per gallon) actually DECREASED rather than increased. I looked the chip up online, since it came with instructions that were microscopic, and very little contact or company info.
