I'm considering buying a used ecu to apply my Ecutek tuning to so that if I ever do have to go into the dealer for something or eventually want to return the car to stock to sell I will have my "virgin" factory ECU ready to go. For the ~$100 or so it costs to get a used ECU it seems worth it.

You will need to do the 30 minute proceedure ach time you change ecu. Thats the easy part, crawling uner the dash to physically swap out the ecu is the harder part :-)
if your doing the ecu swap remember to put in you vin to the new ecu, its not necessary to start or run car but dealer may pick vin doesnt match, you only need to do that once to new ecu though
