2015+ Chrysler, Dodge, Jeep & Ram vehicles come from the factory with an encrypted (locked) powertrain control module (PCM) that cannot be tuned. Because of this, DiabloSport handheld tuners will not work with any 2015 and up FCA vehicle with an unmodified (stock) PCM. These vehicles require a DiabloSport modified PCM installed prior to any tuning. DiabloSport offers year, make and model specific PCM modules for sale that will allow you to use a DiabloSport handheld tuner after installation.

Do not attempt to tune any 2015+ FCA vehicle without a DiabloSport Modified PCM installed as it may cause irreparable damage to your vehicle’s computer. This line of modified PCM’s are for off-road use only and are not available for sale or use on pollution controlled vehicles in the state of California or in other states that have similar emission regulations.

You can purchase DiabloSport modified PCM’s for select Mopar vehicle applications here.
