This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2020 Chevrolet Traverse 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.

I recently replaced the ECM on my 2020 Chevrolet Traverse with this VIN-programmed unit, and I couldn’t be happier with how smooth everything went. The module arrived sooner than I expected, and installation was truly hassle-free—just plugged it in, and it fired right up. It’s impressive how precise the programming was; there were no error codes or weird issues afterward. I also appreciated the helpful guidance from their support team when I had a couple of questions during setup. Overall, this was a solid buy that saved me a lot of time and stress.
