Traded my 2012 civic si in at echolon ford Strafford NJ for a 2013 mustang gt ... the si was stock but has flash pro locked to it .. I just want to unlock the flash pro or sell it.

Car is grey had about 14k-16k when I traded it in small ding on drivers door and tiny rock chip on hood.

As of right now my flash pro I'd just a expensive paper weight .. it's locked to the si from when I disabled the o2 sensor from when I ust to have a down pipe on it
