Description
2008 Chrysler 300 3.5L ECM / ECU – VIN Programmed | Updated
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 with IMMO or PATS may require key programming after installation. This is normal.
For a 100% plug-and-play solution with no relearns, your original ECU must be sent in for cloning. We transfer all security data to the replacement unit.
👉Add the cloning service as a bundle at checkout — $200 CAD / $140 USD
A prepaid shipping label will be emailed to you.
If cloning is not selected, the ECU will be VIN programmed, and a key relearn will be required after installation.

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.
