Description
2014 GMC Savana 5.3L ECM / ECU – VIN Programmed | Plug & Play
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2014 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.

I was a bit nervous about replacing the ECM on my 2014 GMC Savana, but this unit made the whole process surprisingly easy. It arrived quickly and was already programmed for my VIN, which saved me from a lot of hassle. Installation took no time at all, and once everything was hooked up, the engine fired right up without a hitch. It’s been running smoothly ever since, with no error codes or performance issues. Definitely a solid product that delivered exactly what it promised.
When my GMC Savana started having engine issues, I knew I needed a reliable replacement ECM. This module arrived sooner than expected and was ready to go right out of the box, matching my VIN perfectly. The plug-and-play design meant I didn’t have to mess with complicated wiring or programming, which was a huge relief. It’s been a couple of weeks now, and the van runs like new again, with no check engine light or glitches. I appreciate how hassle-free this whole experience was.
