This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2014 Buick LaCrosse 2.4L 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.

I recently installed the 2014 Buick LaCrosse 2.4L ECM and was amazed at how smoothly everything went. The unit arrived quickly, and it was already VIN programmed, which saved me a ton of time. Installation was a breeze—truly plug and play, just like described. After putting it in, my car fired right up with no issues and runs perfectly now. I also appreciated the helpful customer support who answered my questions promptly. Definitely a stress-free experience from start to finish.
