Typically on a bike, you map a piece of hardware (Dynojet Power Commander for example) that goes inline and alters the signal coming from the ECU. There's a couple of exceptions as with certain bikes the factory makes "kit" ECU's and you program them directly. With cars, I've never seen an inline piece, and it seems like you need an act of congress to "map" your computer.
For what it's worth there is a tuning company, Vishnu Performance Systems, that makes a tuning product available for the BMW 3.0 liter twin turbo engine (3-Series, 5-Series) which is installed in-line like you describe above common for bikes. This is the only software tuning for a car I know of - and that is probably limited knowledge! - that functions in this way. I assume, probably incorrectly, the software map for a car is more involved than for a bike and therefore requires a complete re-write of code.
