GPEC2 / GPEC2A PCM unlock file service

CMDFlash GPEC Unlock File Service

CMDFlash GPEC files may be accepted for our unlock file service depending on protocol. Read your Dodge, Jeep, Chrysler, or Ram PCM with CMDFlash, upload the original file, and receive a processed file to write back for supported tuning preparation, where legally permitted.

CMDFlash organizes coverage by driver/protocol, so the specific GPEC driver you used and the read method matter. We accept CMDFlash reads when the dump is complete and the GPEC application is supported.

  • Nationwide file service
  • Mail-in PCM option
  • Shop / tuner friendly
  • Secure file upload
  • Fast turnaround available
  • Legal-use only
CMDFlash GPEC Unlock File Service — supported tool
Detail

CMDFlash GPEC drivers and protocols

Upload the original CMDFlash read with a PCM label photo, VIN, part number, and read method so we can confirm the GPEC family and that the file is valid for processing. The right CMDFlash driver and a complete read are what make the file usable.

If the read came through a protocol that does not fully cover your ECU, we tell you before charging. Keep your original backup and use battery support when writing the returned file back.

No read/write tool? You can mail in your PCM and we service the physical unit directly, then ship it back.

07 · Before you order

What you need before ordering

Do not know if your PCM is GPEC2, GPEC2A, GPEC3, GPEC4, GPEC4LM, or GPEC5? Upload a clear photo of the PCM label with your vehicle year, make, model, engine, VIN, and tool used to read the file.

  • Original ECU/PCM read file
  • PCM label photo
  • Vehicle year, make, model, engine
  • VIN
  • PCM part number
  • Tool used to read the file
  • Read method: OBD, bench, or boot
  • Description of what you need
  • Battery support recommended when writing back

Year, make, and model alone are not enough to guarantee support. ECU family, PCM part number, software version, file format, and read method all matter.

Have everything ready? Upload your read and pay online, or mail in the PCM if you cannot read the file.
