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.

I was pretty nervous replacing the ECM on my 2015 Toyota Sienna, but this unit made the whole process surprisingly smooth. It came pre-programmed to my VIN, so I just plugged it in and everything fired right up without a hiccup. Shipping was quicker than I expected, and when I called their support with a couple questions, they were knowledgeable and friendly. Since the install was true plug-and-play, I didn’t need to spend hours troubleshooting or coding anything myself. Overall, this saved me a lot of time and stress, and my van runs great now. Definitely recommend if you need a reliable ECM swap.
