What Are GPEC and NGC ECUs? Understanding FCA Stellantis Module Families
FCA Stellantis (formerly Fiat Chrysler Automobiles) uses two primary ECM families across its Chrysler, Dodge, Jeep, and RAM vehicle lineup: the GPEC family (Gas Powertrain Engine Controller) and the NGC family (Next Generation Controller). Understanding which module your vehicle uses is the first step toward a successful clone.
GPEC Family — Gas Powertrain Engine Controllers
The GPEC series controls fuel injection, ignition timing, emissions, and immobilizer functions on gasoline-powered FCA vehicles. The family has evolved through four generations:
| Module | Generation | Architecture | Key Feature |
|---|
Para una revisión inicial, comparte año, marca, modelo, problema general, síntoma general, ubicación del taller y equipo disponible.
| GPEC2 | Gen 2 | Dual-processor | EEPROM + Flash memory |
|---|---|---|---|
| GPEC2A | Gen 2A | Enhanced dual-processor | Improved security seed; EEPROM + Flash |
| GPEC3 | Gen 3 | Multi-processor | Advanced security; EEPROM + Flash + SRI |
NGC Family — Next Generation Controllers
The NGC series is used primarily on older Chrysler, Dodge, and Jeep platforms with Chrysler's legacy engine management architecture:
| Module | Application | Key Feature |
|---|---|---|
| NGC4 | 2003–2012 Chrysler/Dodge/Jeep | Security bytes (no EEPROM) |
| NGC4A | 2007–2014 Chrysler/Dodge/Jeep | Enhanced security bytes |

Why FCA Stellantis ECMs Require Professional Cloning
Para una revisión inicial, comparte año, marca, modelo, problema general, síntoma general, ubicación del taller y equipo disponible.
Immobilizer Lockout (No Start): The GPEC3 and GPEC2A modules use a rolling security seed that is paired to the vehicle's SKREEM (Sentry Key Remote Entry Module) or TIPM. A non-cloned replacement will fail the security handshake and prevent the engine from cranking.
Para una revisión inicial, comparte año, marca, modelo, problema general, síntoma general, ubicación del taller y equipo disponible.
SRI (Service Reminder Indicator) Reset: GPEC3 and GPEC2A modules store the SRI (oil life, maintenance intervals) in the EEPROM. A non-cloned replacement resets these values, causing incorrect service reminders and potential warranty disputes.

Data Cloned by Module Type
The cloning process differs slightly between GPEC and NGC families due to their internal architecture. Here is exactly what we clone for each module type:
Para una revisión inicial, comparte año, marca, modelo, problema general, síntoma general, ubicación del taller y equipo disponible.
| GPEC3 | Yes | Yes | Yes | Yes | Yes |
|---|---|---|---|---|---|
| GPEC2A | Yes | Yes | Yes | Yes | Yes |
| GPEC2 | Yes | Yes | Yes | Yes | Yes |
| GPEC | No | Yes (Hardware/OS) | Yes | N/A | N/A |
| NGC4A | No | Yes | Yes | N/A | Yes |
| NGC4 | No | Yes | Yes | N/A | Yes |
Para una revisión inicial, comparte año, marca, modelo, problema general, síntoma general, ubicación del taller y equipo disponible.
> Important note for NGC4: The NGC4 does not have a separate EEPROM. The cloning process reads the security bytes from the original module and writes them to the replacement, along with the correct Flash calibration.

Programming Car Pro vs ECU Hero: Full Comparison
Both Programming Car Pro and ECU Hero support FCA Stellantis ECM cloning. Here is how the two services compare on the factors that matter most to mechanics, shops, and vehicle owners:
| Factor | Programming Car Pro | ECU Hero |
|---|---|---|
| Service Type | Mail-in professional cloning | DIY software tool (requires hardware) |
| Turnaround | Same day (or next morning) | Depends on user skill and equipment |
| Inbound Shipping | FREE prepaid label emailed to you | N/A (you own the tool) |
| Return Shipping | FREE same-day return | N/A |
| Equipment Required | None — we handle everything | ECU Hero hardware + tokens required |
| Token Cost | None — included in service | 2 tokens per clone (original + replacement) |
| GPEC3 Support | Yes | Yes |
| GPEC2A Support | Yes | Yes |
| GPEC2 Support | Yes | Yes |
| GPEC Support | Yes | Yes |
| NGC4A Support | Yes | Yes |
| NGC4 Support | Yes | Yes |
| Warranty | 12 months | Depends on hardware warranty |
| Tech Support | WhatsApp + phone (786) 478-2531 | Email support |
| Skill Required | None — ship and receive | Moderate to advanced |
The key difference: ECU Hero is a DIY tool that requires purchasing hardware, learning the software, and spending tokens per clone. Programming Car Pro is a done-for-you service — you ship the modules, we clone them, and ship them back the same day at no additional cost for shipping.

Real Cost Comparison: Programming Car Pro vs Dealer wiTECH
The dealer alternative to ECM cloning on FCA Stellantis vehicles requires a wiTECH 2.0 subscription, a StarSCAN or wiTECH MicroPod 2 interface, and dealer-level access to the FCA server for security token authorization. Here is what that typically costs:
| Cost Component | FCA Dealer | Programming Car Pro |
|---|---|---|
| New OEM ECM (GPEC3 Charger 5.7L) | $550–$950 | $0 (use your salvage unit) |
| wiTECH programming labor | $200–$400 | Included in service |
| Security token authorization | $75–$150 | Included |
| Inbound shipping | N/A (you drive in) | FREE prepaid label |
| Return shipping | N/A | FREE same-day |
| Total estimated cost | $825–$1,500 | Service fee only |
| Turnaround | 2–5 days (parts + scheduling) | Same day |
Most customers save $600–$1,200 compared to the dealer route, with faster turnaround and no need to schedule an appointment or leave the vehicle at the dealership.
