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

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 was a bit nervous replacing the ECM on my 2016 Toyota Sienna, but this unit made the process so much easier. It arrived quickly and was already programmed to my VIN, which saved me a ton of hassle. Installation was straightforward—just plug it in and go. Since the swap, the vehicle runs smoothly without any warning lights or hiccups.
