I remember seeing a segment on TV years ago... I think it was on Beyond 2000 (anyone ever watch that?). It was about this device that reproduced the engine noises of various high-end cars and routed them through the stereo system. It must have connected to the car computer or something to get tachometer readings, but my memory is fuzzy.
