Description
2019 Chevrolet Impala 3.6L ECM / ECU – VIN Programmed | Plug & Play
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2019 Chevrolet Impala 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.

Andrew Moore –
I was impressed with how simple the installation was—this ECM came pre-programmed for my 2019 Chevy Impala, and it truly was plug-and-play. It delivered a smooth performance right out of the box, and the engine runs perfectly now. Shipping was quicker than I expected, and their customer support was helpful when I had a couple of questions before buying. Definitely a reliable replacement part that saved me time and hassle.

Swapped out my old ECU with this one in no time—true plug-and-play and it fired right up without a hitch. Super impressed with the quick delivery too!
