Will This Fix My Problem?
Honest answer: here's exactly what this service fixes — and what it doesn't.
Fixes:
- ✓HP Tuners / EFILive returns "vehicle not supported" or "security violation" on your GPEC PCM
- ✓Tuner software won't allow reads or writes of the factory calibration
- ✓You bought a used GPEC2 / GPEC2A ECM and need to unlock it before flashing your own tune
- ✓GPEC2A Hellcat owner blocked from tuning by a Stellantis security update
- ✓Dealer reflashed the module and re-locked it after a service campaign
Won't fix:
- ✗Hardware-failed PCM (we unlock, not repair internal damage)
- ✗Tuning itself — we unlock, you tune (or work with a tuner)
- ✗Emissions defeat, delete files, or emissions-bypass services (we do not offer this)
- ✗Non-GPEC modules (GM, Ford, TCMs) — those are separate services, text us to confirm

If you can read your Continental GPEC file with a supported tool (KESS3, AutoTuner, Flex, BitBox, FoxFlash, KT200, CMDFlash, or Dimsport), use our instant online file service: upload your original read and we byte-check it free — supported versions (GPEC2, GPEC2A, and many GPEC3 reads) unlock instantly for $150. Mail-in ($250) covers files we cannot match online and customers who cannot read the file themselves.
