Description
2020 Dodge Charger 6.4L ECM / ECU – VIN Programmed | Plug & Play
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2020 Dodge Charger 6.4L 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 ordering an ECM/ECU online, but this 2020 Dodge Charger unit arrived quickly and was truly plug-and-play as promised. The VIN programming saved me a ton of hassle, and installation went smoother than I expected—no weird codes or glitches afterward. It’s been a few weeks now, and the car runs flawlessly, with all systems responding just like before. Customer support was also super helpful when I had a quick question about the setup. Overall, this was a solid purchase that got my Charger back on the road without any headaches.
