What is a PCM unlock?

A PCM unlock removes the factory encryption from the Powertrain Control Module so professional tuning tools can read and write calibration data. On most 2015+ Dodge, Jeep, Chrysler, and RAM vehicles, unlocking is required before custom tuning can be performed.

Why do 2015+ Dodge, Jeep, and RAM vehicles require unlocking?

Starting in 2015, FCA implemented security protocols that restrict tuning access through the OBD port on many vehicles. Unlocking enables calibration access so changes to airflow, torque management, fueling, and other tables can be flashed safely.

Do I have to mail in my PCM?

Yes. The unlock process is performed on a bench and requires the PCM to be removed from the vehicle and shipped in for service. Once unlocked, the PCM can typically be read and written via OBD using supported tuning platforms.

How long does the PCM unlock process take?

Typical turnaround is 1–3 business days after the PCM is received, plus shipping time. Tracking is provided when the module ships back.

What vehicles commonly need a PCM unlock?

Most 2015+ Dodge, Jeep, Chrysler, and RAM vehicles with encrypted controllers require unlocking before tuning. Common examples include 2015+ Charger, Challenger, 300, Grand Cherokee, and RAM 1500. If you are unsure, provide your VIN and we can verify.

What controllers are supported for PCM unlocking?

Common encrypted FCA controllers include GPEC2A, GPEC3, E90, and E92. Compatibility can vary by year and model, so VIN verification is recommended if you are not sure which PCM your vehicle uses.

Is a PCM unlock safe?

Yes. Unlocking is designed to enable calibration access and does not change stock drivability by itself. The vehicle will operate normally on a stock calibration or a custom tune after unlocking.

Can I return the PCM to stock after it is unlocked?

Yes. An unlocked PCM can still run a stock calibration file. Unlocking enables access, but you can flash stock or custom files as needed using a supported tuning platform.

Will unlocking void my warranty?

Unlocking enables tuning access, and any calibration changes may affect manufacturer warranty coverage. If warranty is a concern, some customers keep their original PCM stock and use a spare PCM for modifications.

Do I still need HP Tuners credits after unlocking?

Yes. Unlocking enables access, but you still need the appropriate interface and licensing (credits) to read, license, and flash the vehicle with HP Tuners or other supported tools.

Can you tune my vehicle after unlocking?

Yes. We offer custom remote tuning for bolt-ons, camshaft upgrades, injector scaling, boost setups, and torque model optimization. Pairing an unlock with a custom calibration is the best way to improve performance and drivability.

Warranty Information

N2 Speed Remote Tuning Warranty & Support Policy

At N2 Speed, we take pride in delivering high-quality, data-driven remote tuning services designed to enhance your vehicle’s performance, reliability, and drivability. While every tune is custom-built to match your exact setup, it’s important to understand the nature and limitations of remote calibration work.

Warranty Coverage

30-day calibration support period for file revisions related to drivability, idle, or performance adjustments.
File updates to accommodate minor hardware or fuel changes within the same setup (e.g., intake or exhaust modifications).
Email support for troubleshooting and data log review during the active support period.

Exclusions

Because tuning involves modifying factory calibration parameters, no warranty can be offered on the vehicle, powertrain, or any mechanical/electrical components affected by these changes. This includes, but is not limited to:

Engine, transmission, or drivetrain damage resulting from misuse, mechanical failure, or improper installation of aftermarket parts.
Faulty sensors, vacuum leaks, wiring issues, or hardware malfunctions unrelated to the calibration.
Issues caused by fuel quality, poor maintenance, or unauthorized tune modification by the customer or third parties.

Customer Responsibility

Customers are responsible for ensuring the following before and during the tuning process:

The vehicle is in proper working condition prior to tuning (no check-engine lights, leaks, or faulty sensors).
All modifications and fuel type information are accurately disclosed prior to tuning.
Correct HP Tuners or DiabloSport hardware and software are used for reading and flashing the PCM.

Disclaimer

Remote tuning involves variables beyond our control, including mechanical condition, installation quality, and environmental factors. Therefore, N2 Speed’s remote tunes are sold “as is”, with no implied warranty of merchantability or fitness for a particular purpose.

By purchasing a remote tuning service, the customer acknowledges these terms and accepts full responsibility for any outcomes related to the calibration and vehicle operation.

Our Commitment

While mechanical components cannot be warranted, N2 Speed stands behind every tune we deliver. We ensure each calibration is safe, optimized, and matched to your specific setup. Our mission is to provide you with confidence and proven performance in every tune — whether you drive a Corvette, Charger, Ram, or Jeep.
