Yes, the ebay product is a scam.
No, the computer will not "learn" that it's there. All this thing does is take an input, transform it, and output the result. The computer has no idea this is going on. The computer can only make decisions based off of the values that it is given.
It's like if you were to put a thermometer inside an 80 degree room. It wouldn't be able to tell you the outside temperature (and no, this isn't a thermometer with a remote sensor). Same sort of thing.
These things are all based off of the principal that if you trick the ECM into thinking certain conditions exist, it will adjust various properties of the engine to the point where you gain power, torque, mpg, etc. You can pick up some of the 3 with certain chips or programmers. But not ones that boast claims like this (and only alter a single parameter!).
Two things when buying things like this: 1) If it looks too good to be true... and 2) You get what you pay for.
