Mail-In PCM Unlock Service
No read/write tool? No problem. ECU Flash Cartel offers a nationwide mail-in PCM unlock service for Dodge, Jeep, Chrysler, and Ram GPEC controllers. Remove your PCM, ship it to us, and we service the physical unit directly — then ship it back ready for the next step in your tuning workflow, where legally permitted.
Mail-in is the right choice when you cannot read the PCM yourself, when a bench/boot read is required and you do not have the setup, or when you simply prefer to hand the unit to us. If you do have a supported tool, the file-upload option is faster — read your file, upload it, and receive the processed file back.

- Shop / tuner friendly
- Secure file upload
- Fast turnaround available

How mail-in service works
Remove the PCM from the vehicle, then request a mail-in quote so we can confirm your application and pricing. Package the unit safely and ship it to ECU Flash Cartel. We unlock / service the PCM, verify the work, and ship it back. Install it and continue the tuning workflow with your tools where legally permitted.
Include your vehicle year, make, model, engine, VIN, and PCM part number with the unit so we can confirm the GPEC family. Mail-in PCM unlock starts at $249, and PCM clone + unlock service is also available (starting at $399) on supported applications.
No read/write tool? You can mail in your PCM and we service the physical unit directly, then ship it back.
