Description
2008 Chrysler 300 3.5L ECM / ECU – VIN Programmed | Plug & Play
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2008 Chrysler 300 3.5L 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.

I was a bit nervous about ordering an ECM online, but this unit for my 2008 Chrysler 300 arrived quickly and was already programmed to my VIN, which made installation a breeze. I swapped it out myself in my garage without any hiccups, and the car fired right up with no issues. It really felt like a plug-and-play solution, saving me a huge headache compared to what I’d read about reprogramming these modules. Customer support was helpful when I called with a couple of basic questions, which gave me extra confidence. Overall, a great experience that got my car running like new again. Definitely would recommend to anyone needing an ECU replacement.
