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.

Diego Peterson –
I was a bit nervous about replacing the ECM on my 2014 Lexus GS350, but this unit arrived ready to go and programmed to my VIN, which made the install seamless. The plug-and-play design saved me so much time, and the car fired up perfectly without any hiccups. Shipping was quick, and the support team was helpful when I had a couple questions before purchasing. Definitely a worthwhile buy if you need a reliable ECU replacement.
