Description
2018 Chrysler 300 3.6L ECM / ECU – VIN Programmed | Updated
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2018 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 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.

Andrew Walker –
Exact fit for my 2018 Chrysler 300, installed in minutes with zero hassle—highly recommend!
Super quick shipping and the ECU worked flawlessly right out of the box, no programming headaches at all.
Plugged it in and the car fired up immediately; saved me a ton of time and the support team was really helpful.
This ECM was spot-on for my Chrysler, made the swap effortless and the car runs perfectly now.
Arrived faster than expected and was truly plug-and-play—couldn’t ask for a smoother upgrade!
