GPEC2 / GPEC2A PCM unlock file service

FoxFlash GPEC2A Unlock File Service

FoxFlash boot/bench GPEC reads may be accepted for our unlock file service. Read your Dodge, Jeep, Chrysler, or Ram PCM with FoxFlash, upload the original file, and receive a processed file to write back for supported tuning preparation, where legally permitted.

FoxFlash is a capable bench/boot tool with broad protocol support. We accept FoxFlash reads when the dump is complete and the GPEC application is supported, and confirm before charging if a read cannot be used.

FoxFlash GPEC2A Unlock File Service — supported tool
Detail

FoxFlash bench and boot GPEC reads

Bench and boot reads usually deliver the most complete GPEC data, and FoxFlash supports both on many applications. Upload your original read plus a PCM label photo, VIN, part number, and read method so we can confirm the GPEC family and validity.

Keep your original backup and use battery support when writing the returned file back. If a FoxFlash read is OBD-based, tell us — depending on the ECU it may need a bench or boot read instead.

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.
