    No, the map is programmed on your ECU.

    When you remove the power, the computer will reset it's learned memory for timing, etc.. Your car won't run quite as good until it re-learns it's most efficient parameters.

    There is a way to fool the computer to relearn it very quickly. Search for vishnu ECU remap trick. I think it gets you back to "close" to what the ECU had before you removed power.
