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 about replacing the ECU on my 2020 Toyota 4Runner, but this unit made the whole process incredibly smooth. It arrived surprisingly fast and was already programmed to my VIN, so I didn’t have to worry about any complicated setup. Installation was straightforward—just plug it in and everything fired right up without any issues. After swapping it out, the truck runs just like new, if not better. The tech support team was also really helpful when I had a quick question before installation, which gave me a lot of confidence. Definitely a solid buy for anyone needing a reliable ECM/ECU replacement.
