I think it depends on the car you own. If the "subculture" exists, then I think remapping the ECU/PCM should be affordable. I have also been curious about such products like Megasquirt (see
here and
here, but ICE only,
). What I like is that they modify the fuel-injector maps without going "inside" the car-puter, so they should work on most ICE drivetrains.
