Each unit is VIN-programmed, updated, and fully tested for a true plug-and-play installation with no dealer visit required.

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 with IMMO or PATS may require key programming after installation. This is normal.
For a 100% plug-and-play solution with no relearns, your original ECU must be sent in for cloning. We transfer all security data to the replacement unit.
👉Add the cloning service as a bundle at checkout — $200 CAD / $140 USD
A prepaid shipping label will be emailed to you.
If cloning is not selected, the ECU will be VIN programmed, and a key relearn will be required after installation.

Carlos Wright –
I recently replaced the ECM on my 2014 Chrysler 300 with this unit, and I couldn’t be happier with how smoothly everything went. The module arrived quickly, and it was clear right out of the box that it was already programmed with my VIN, which saved me a ton of time and hassle. Installation was straightforward—just plug it in and start the car. I was worried I might hit some technical snags, but the customer support team was really helpful and responsive when I had a couple of questions. Overall, it feels like I’m driving a fresh car again, and I would definitely recommend this to anyone needing a replacement ECM.
