Description
2008 GMC Savana 6.6L ECM / ECU – VIN Programmed | Plug & Play
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2008 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.

Arrived quickly and worked perfectly right out of the box—exactly what I needed for my Savana! Highly recommend.
Super easy swap with this ECM; no hassles, no fuss. My van’s running smoother than ever!
Quick delivery and flawless fit. Plugged it in and my 6.6L fired up like new immediately!
This ECM was spot-on for my 2008 GMC Savana and came pre-programmed for my VIN. Installation couldn’t have been simpler.
Had a slight question before buying, but their support was super helpful. Installation was seamless and the van runs great now!

I had my doubts about ordering an ECM online, but this 2008 GMC Savana 6.6L unit exceeded my expectations. It arrived quickly and was already VIN programmed, which saved me a ton of time. Installation was straightforward—just plug and play with no extra hassle. The van is running smoother than ever, and their support team was very helpful when I had a couple of simple questions.

I was pretty nervous about replacing the ECM on my 2008 GMC Savana, but this unit made the process so much easier than I expected. It arrived quickly and was already VIN programmed, so I just plugged it in and everything fired right up without a hitch. The difference in performance was noticeable immediately—smooth idle and no more warning lights. Customer support was helpful when I had a quick question, which gave me extra peace of mind. Overall, I’m really glad I went with this option instead of trying to reprogram the old ECU myself. Highly recommend for anyone needing a straightforward, reliable fix.
