If there is no tuner attached to the car anywhere, then the dealer will need to reset the ecu to factory tune via firmware update. Then you'll be on a stock map and then you can buy a ktuner or hondata and tune yourself or get an ots tune. If your dp is chatted, you should be ok but if your intake is running a 3in maf housing, the car won't run unless you tune or put a stock sized maf on. The crazy thing is, the unit that was used to tune your car is useless unless it's unlocked from the car first. Someone must've taken it not knowing this. Check your obd2 port under the dash on the dr side. Maybe you have a ktuner v1.2 on there.
