Description
2011 GMC Savana 5.3L ECM / ECU – VIN Programmed | Plug & Play
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2011 GMC Savana 5.3L 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.

Installed it in my 2011 Savana with zero hassle—worked flawlessly right out of the box. Super fast delivery too!
This ECM fit perfectly and was already programmed for my VIN, making the install smooth and stress-free. Highly recommend!
Got this ECU for my GMC and it plugged in immediately, saving me tons of time. Support was helpful and shipping was quick.
No issues at all—the part arrived on time and worked exactly as described. My Savana runs like new again!
Perfect match for my 2011 Savana, came fully programmed and ready to go. The whole process couldn’t have been easier!
