Description
2014 Chrysler 300 3.6L ECM / ECU – VIN Programmed | Plug & Play
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2014 Chrysler 300 3.6L models.
Each unit is VIN-programmed, updated, and fully tested for a true plug-and-play installation with no dealer visit required.
Built to OEM standards for reliability, calibration accuracy, and long-term performance.
Strict Testing & Quality Assurance
Every ECU is inspected, refreshed, and verified through advanced diagnostic tools. Testing includes:
-
Complete communication & CAN-bus verification
-
Sensor input/output and signal integrity checks
-
Injector & ignition pulse simulation
-
Power, ground, and load-circuit analysis
-
Flash memory integrity and checksum validation
-
Thermal and voltage-stress testing to confirm reliability
This ensures a fully functional, reliable, plug-and-play module you can install with confidence.
Important Note
Some vehicles equipped with IMMO (Immobilizer) or PATS (Passive Anti-Theft System) may require additional key programming after installation. This is normal for models where security data must be synchronized with the vehicle’s body control system.
For a 100% plug-and-play solution with no relearns, no key programming, and no compatibility issues, we recommend our ECU Cloning Service, which transfers all original security, immobilizer, and configuration data directly into the replacement unit.

Carlos Wright –
I recently replaced the ECM on my 2014 Chrysler 300 with this unit, and I couldn’t be happier with how smoothly everything went. The module arrived quickly, and it was clear right out of the box that it was already programmed with my VIN, which saved me a ton of time and hassle. Installation was straightforward—just plug it in and start the car. I was worried I might hit some technical snags, but the customer support team was really helpful and responsive when I had a couple of questions. Overall, it feels like I’m driving a fresh car again, and I would definitely recommend this to anyone needing a replacement ECM.
