Chrysler PCM Unlock File Service
ECU Flash Cartel offers nationwide Chrysler PCM unlock file service for GPEC2 and GPEC2A controllers. The Chrysler 300 and 300C share their platform with the Dodge Charger, so the same supported GPEC PCMs appear across 3.6L Pentastar, 5.7L HEMI, and 6.4L SRT applications. Upload your read, pay online, and receive the processed file to write back, where legally permitted.
If you cannot read the PCM, mail in the unit and we service it directly. The service supports shops, mobile programmers, tuners, and DIY owners.

Chrysler applications we cover
The 300 and 300C are the core Chrysler applications for this service, tracking closely with the Charger because the platforms are mechanically related. Many 3.6L Pentastar, 5.7L HEMI, and 6.4L SRT cars carry supported GPEC controllers. Support is confirmed by PCM label, part number, ECU family, and the read file.
Include the PCM label photo, VIN, part number, and your tool and read method when ordering. We confirm the GPEC family and read completeness before charging. See our Chrysler 300 page for model-specific details.
No read/write tool? You can mail in your PCM and we service the physical unit directly, then ship it back.
