Assuming you have a PFC, the only way to reset the map(back to the original settings) is to manually hit the "all data init" function in the commander. I'm pretty sure if the battery has been disconnected for a while, the PFC will be "reset" just like the stock ECU. Meaning the tuned map is still in the PFC, but you'll probably have to go through the idle learning process.
