<Does anyone know what this is and how/if it works?>

It a way to get some of your hard earned money! Don't waste your time and
money on crap like this. The seller feedback does make for some great
reading, though. The same module  (it must fit every car ever made, as long
as it's FI).on a Ford Mustang shaved 2.5 seconds of the ET!! Amazing! In
the real world it takes a lot to shave 2.5 seconds off a cars ET in the 1/4
mile. Save your money!!!
