Define "dies"... If the computer shorts out it's dead anyway and no laptop or phone will do anything about it, just like any ECU. Baring that they are extremely reliable and once setup just run and run. If there is a re-boot while running (usually only if you are screwing with it) you see a hiccup but the MS ECU tends to recover before the engine drops more than 100rpm (think slight stumble).

If so, is there a smartphone interface so you don't have to upload them from a laptop? I'm thinking about what happens if the controller dies while you're on a trip. On my own car I am only dependent upon the ignition ECU, and I carry a spare for that (Duraspark is my primary ECU and the original Bosch unit is my backup).
