Description
2007 Buick Lucerne 3.8L ECM / ECU – VIN Programmed | Plug & Play
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2007 Buick Lucerne 3.8L 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.

Swapped out my old ECM with this one and it fired right up—super easy install and no hiccups. Arrived quicker than I expected too!

I was pleasantly surprised by how quickly this ECM arrived and how seamlessly it fit into my 2007 Buick Lucerne. The VIN programming was spot on, so there was no hassle with compatibility or reprogramming on my end. Installation was straightforward, truly a plug-and-play experience, and my car has been running perfectly since. The support team was also helpful when I had a quick question, which made the whole process much smoother.
