Description
2012 GMC Savana 6.6L ECM / ECU – VIN Programmed | Plug & Play
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2012 GMC Savana 6.6L 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 was a bit nervous ordering an ECM online, but this one for my 2012 GMC Savana fit perfectly and was programmed right out of the box. Installation was straightforward—I had it swapped in and running without a hitch the same day it arrived. The engine feels smooth, and all the warning lights stayed off, which gave me peace of mind. Shipping was surprisingly quick, which helped me get back on the road sooner than expected. Overall, this was exactly what I needed to get my van back in top shape without any guesswork.

This ECM arrived quickly and was exactly what I needed for my 2012 GMC Savana 6.6L. Installation was straightforward since it came VIN programmed, making it a real plug-and-play solution. After swapping it in, my engine ran perfectly with no warning lights or issues. The seller’s support was also helpful when I had a couple of questions before purchasing.
