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 vehicles 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 a bit nervous ordering an ECU online, but this one exceeded my expectations. It came VIN programmed and ready to go, so I just plugged it in and everything fired right up. The difference in my Jeep’s responsiveness is noticeable, and the whole process was hassle-free. Customer support was also helpful when I had a quick question about installation.
The 2018 Jeep Grand Cherokee 3.0L ECM I purchased worked perfectly out of the box. No complicated setup or tuning required since it was pre-programmed for my VIN, making the swap almost effortless. The shipping was prompt and packaging secure, which gave me confidence in the purchase. My Jeep drives like new again
