Description
2009 GMC Sierra 6.0L ECM / ECU – VIN Programmed | Plug & Play
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2009 GMC Sierra 6.0L 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.

Swapped out my old ECM with this unit, and it fired right up—super fast shipping and zero hassle installation. Exactly what I needed!
Got this programmed ECM for my 2009 Sierra, and it fit perfectly with no extra tweaks. Quick delivery and solid support made the whole process smooth.
This plug-and-play ECU saved me a ton of time—no programming headaches, and the truck runs like new. Highly recommend!
Fast arrival and completely ready to go right out of the box. Took me less than an hour to get back on the road with this 6.0L ECM.
Perfect fit and flawless performance from day one. If you want a no-fuss replacement, this is it.
