Will This Fix My Problem?
Honest answer: here's exactly what this service fixes — and what it doesn't.
Fixes:
- Preparing tuned vehicle for warranty / dealer service
- Selling or returning a leased vehicle that was tuned
- Failed aftermarket tune flash — module in unstable state
- Removing performance tune before emissions inspection
- Stock-class racing — need verifiable OEM calibration
- Recovering from "computer says modified" warranty denial scenarios
Won't fix:
- Hardware-failed PCM (this flashes software, doesn't repair the board)
- Modules with no OEM calibration available (rare; we tell you upfront if so)
- Restoring engine to stock after physical modifications (only the cal is restored — not headers, cams, etc.)
Before you order
You diagnose, we service the module.
We don't have your car and we don't diagnose it. Order once you or your mechanic have confirmed this module is the cause. If the work is completed and the car still has the same symptom because of another fault, the work is still done — a bench re-test under warranty is free.
A clone copies what is in your module.
We transfer the data as we read it. If another shop or tool already worked on the module — an unfinished clone, a tune, a delete — that data can come across too. Tell us before you ship.
What "plug-and-play" means.
No dealer programming should be needed when your original data is intact, the donor matches your module (same type, hardware and software family) and the rest of the car works. It isn't a promise that the car will start or run.
Chrysler, Dodge, Jeep, or Ram?
Mopar modules (GPEC2 / GPEC2A, NGC, JTEC) take a different toolchain and are priced separately at $350. Use our Mopar Stock OEM Re-Programming service for those.
