Hi

No it is a flash tuner, so it takes off the info from the ECU then puts it flash files onto the ECU. At anyyime you can then put back the standard tune.

With Bluefin once it has been used it is useless unless reset by Superchips.

With the Dreamm Science i am led to believe that you can put you r standrd map back on the car, then have it re mapped for another car. I am told this can be 3 or 4 times before Dream Science have to reset the handset.....
