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 pretty nervous replacing the ECM on my 2015 Toyota Sienna, but this unit made the whole process surprisingly smooth. It came pre-programmed to my VIN, so I just plugged it in and everything fired right up without a hiccup. Shipping was quicker than I expected, and when I called their support with a couple questions, they were knowledgeable and friendly. Since the install was true plug-and-play, I didn’t need to spend hours troubleshooting or coding anything myself. Overall, this saved me a lot of time and stress, and my van runs great now. Definitely recommend if you need a reliable ECM swap.
