Description
2008 Toyota 4Runner 4.0L ECM / ECU – VIN Programmed | Plug & Play
This Engine Control Module (ECM / ECU) is a genuine OEM replacement for all 2008 Toyota 4Runner 4.0L 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.

Super easy install and shipped quickly—this ECM fit perfectly and had my 4Runner running like new again!
David Morris –
I was a bit nervous about ordering a pre-programmed ECM for my 2008 Toyota 4Runner, but this unit arrived quickly and was exactly as described. Installation was straightforward — it literally just plugged in and fired right up without any hiccups. I’ve had zero issues since swapping it in, and the difference in engine performance is noticeable. Also, customer support was really helpful when I had a couple of questions before buying. Overall, a smooth process from start to finish that saved me a lot of time and hassle.

Swapping the ECM on my 2008 4Runner used to feel like a daunting job until I found this VIN-programmed ECU. The whole process was surprisingly easy; no complicated programming on my end and it just worked after the plug-and-play install. Shipping was fast, which was great because I needed my truck back on the road ASAP. The engine runs smoothly now, and it feels like I have a brand-new vehicle. I’m really glad I didn’t
