2015+ GPEC PCM Unlock Service
Mail-in unlock service for GPEC, GPEC2, and GPEC2A PCMs used in Dodge, Ram, Jeep, and Chrysler vehicles. We unlock your original controller for OBD-II tuning with HP Tuners or DiabloSport. This service does not change the stock calibration.
Need calibration changes too? Choose the unlock-and-tune package for MDS settings, diagnostic-code changes, performance tuning, and other requested calibration work.

How mail-order service works
- Purchase this service.
- Complete the service request form using your order number.
- Remove and securely package your PCM/ECM or module(s).
- Send only the bare PCM/ECM or module(s). Before shipping, remove all plastic or metal brackets, mounting pieces, screws, wiring-harness gaskets, and other accessories. Extra pieces are not part of this service and may not be returned, so please keep them with the vehicle. PCM Tuners is responsible only for the module(s) sent for service.
- We strongly recommend that you use the white 9" x 3" x 12" Pen+Gear brand boxes available at Walmart. They are strong, made in the USA, and cost about $1. Most GM ECM and PCM modules fit in these perfectly. Just add a bit of paper on the ends to prevent the module from sliding in the box during transit.

- We complete the service and return the controller(s) with tracking.
Before you remove the PCM
- Disconnect vehicle power and follow the correct service procedure for your application.
- Do not pry on the connectors. A small amount of isopropyl alcohol around a stubborn connector seal can help it release.
