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.

Receiving the programmed ECM for my 2012 Dodge Challenger was a relief after my old unit failed. The installation was straightforward, truly plug-and-play with no reprogramming needed on my end. It fired right up, and the engine runs smoothly without any error codes. Shipping was quick and the support team was helpful when I had a couple of questions before ordering.

Once installed, my car fired right up and runs flawlessly, with no check engine lights. The team was also helpful when I had a couple of questions. Overall, a smooth experience from start to finish and my Challenger feels like new again.
