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 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.

I recently purchased the 2020 Toyota Sienna ECM, and I couldn’t be happier with how smoothly everything went. The unit arrived quicker than I expected, and installing it was surprisingly straightforward—just plugged it in, and it was ready to go. What impressed me the most was that it came already programmed to my VIN, saving me a ton of hassle and trips to the dealership. My van runs like new, and I appreciate that the tech support team was available to answer a couple of quick questions I had during installation. Definitely a reliable purchase for anyone needing a replacement ECU.
