Description
2010 GMC Sierra 6.2L ECM / ECU – VIN Programmed | Updated
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2010 GMC Sierra 6.2L 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 with IMMO or PATS may require key programming after installation. This is normal.
For a 100% plug-and-play solution with no relearns, your original ECU must be sent in for cloning. We transfer all security data to the replacement unit.
👉Add the cloning service as a bundle at checkout — $200 CAD / $140 USD
A prepaid shipping label will be emailed to you.
If cloning is not selected, the ECU will be VIN programmed, and a key relearn will be required after installation.

Arrived exactly as described and fired right up with zero hassle—perfect for my 2010 Sierra! Super quick delivery too.
This ECM was spot on for my truck, no programming headaches and fully plug-and-play. Everything worked flawlessly from day one.
Fast shipping and the ECU fit without a single glitch. My Sierra runs smoother than ever—definitely recommend this for a straightforward swap.
Plugged it in and bam, good as new! Saved me a ton of time and stress compared to my previous experience with aftermarket parts.
Really impressed with the seamless installation and prompt customer support when I had questions. The truck’s running excellent thanks to this unit!
