Does ECU Flash Tuning Affect Warranty and Flash Counters

If you put the original file back in the car, Porsche cannot detect anything as it is the ORIGINAL.  VRTuned provides you with the ORIGINAL file that you read out.  Others that have a switching unit give you a stock type file where you are switching between fuel maps on a already altered file.  The only flash counter that exists is when file updates are done by the factory PIWIS tool or Porsche related tool.  Other “tuners” that do not know how to devert around this and will show a flash counter change.

For example we had a recent customer with a 997TT that had flashed his car with us.  He had a turbo problem with the mechanical arm that was warrantied.  Porsche reflashed his car from the original firmware of B730 (flash count 1) to a B742 (flash count 2).  The customer went to reinstall his tuned file, but because they changed  his firmware, the tuned file did not work and caused his car to not start.  So he had it brought back to the dealer to be reflashed to firmware B742 (flash count 3).  He then reread out the car and received a new file for his car which was loaded.  At the end of the day, only the Porsche dealer alterations show as flash counts totally 3.

We ALWAYS recommend talking to your dealer about warranty as different dealers interpret rules uniquely. Our statements are true, however we cannot be held responsible for uncontrollable circumstances.
