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 includes a model-specific PCM module 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 tuner will include a CARB Executive Order number, making it 50-state legal.

PCM is not included and OEM PCM must be sent to DiabloSport
