A PCM unlock removes factory encryption from the Powertrain Control Module so professional tuning platforms like HP Tuners and Diablosport (and supported devices) can read and write calibration data for custom tuning. Many 2015+ FCA vehicles use encrypted PCMs that block OBD tuning access until the controller is unlocked. Starting in 2015, FCA implemented security protocols that restrict calibration access through the OBD port. Encrypted controllers such as GPEC2 and GPEC2A (and later variants) typically require a physical unlock first. Without unlocking, tuning software cannot modify key calibration areas such as airflow, torque management, injector data, or boost tables. Yes. PCM unlocking is a bench service that requires the module to be removed from the vehicle and shipped to us. Once unlocked, the PCM becomes readable and writable via OBD using HP Tuners (and supported tuning solutions). Typical turnaround time is 1–2 business days after the PCM is received. Expedited options may be available, and return tracking is provided once the service is completed. Most 2015+ FCA vehicles require unlocking, including: If you’re unsure which controller your vehicle has, contact us with your VIN: sales@n2speed.com. We service encrypted FCA controllers including: If your vehicle uses one of these encrypted modules, unlocking is required before custom tuning can be performed. Yes. The unlock process does not change factory drivability by itself—it only enables calibration access. Once unlocked, the PCM functions normally and can run stock or custom tune files. Yes. An unlocked PCM can still run a factory stock calibration. Unlocking removes the tuning restriction—it does not force a tuned file. Any calibration modification may affect manufacturer warranty coverage. If preserving warranty is critical, consider keeping your original locked PCM and using a spare module for modification. Yes. Unlocking enables access, but you still need a supported HP Tuners interface and the required credits to license and flash the vehicle. Yes. We offer custom remote tuning for: We recommend pairing your PCM unlock with a custom calibration to maximize performance and drivability. Questions? Email sales@n2speed.com. Ready to order?
