Description
2014 GMC Savana 4.3L ECM / ECU – VIN Programmed | Updated
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2014 GMC Savana 4.3L 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 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.

Fit perfectly in my 2014 Savana and worked immediately—installation was a breeze with zero hassle. Highly recommend!
Super fast delivery and the unit came pre-programmed exactly as advertised. Got my van running again in no time!
Plugged it in and it fired right up; saved me a ton of downtime. Very impressed with the easy setup!
This ECM was ready to go right out of the box and the support team answered all my questions quickly. Great experience!
Perfect match for my GMC’s VIN, no complicated programming needed. Made the repair process smooth and stress-free!
