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.

This ECM unit for my 2017 Cadillac ATS was exactly what I needed and arrived quickly. It was programmed to my VIN, so installation was straightforward with no extra coding required. The plug-and-play design saved me a ton of hassle, and my car is running just like new again. Customer support was also very helpful when I had a couple of questions.

This ECM was perfect for my 2017 Cadillac ATS—came pre-programmed and installed without a hitch. Quick delivery and flawless performance!
Swapped out my old ECU with this one, and it fit like a glove. Super easy installation and the car runs like new again.
Got the programmed ECM fast, and it was truly plug-and-play as promised. Saved me a ton of hassle and the car fires right up every time.
The pre-coded ECM for my 2017 ATS arrived faster than expected, and the install was a breeze. Definitely a solid buy if you want no guesswork.
Really impressed with how seamless this ECM replacement was—just plug it in, and you’re good to go. Helped me avoid the shop and keep my ATS running smooth!
