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 2014 Lexus GS450h, but this unit made the whole process surprisingly painless. It arrived quicker than I expected, well-packaged and ready to install right out of the box. The VIN programming was spot on, so once I plugged it in, everything synced perfectly with my car’s systems. Since the install, my car runs smoother and the hybrid system feels more responsive. Definitely a great buy for anyone looking to avoid the dealer hassle and downtime.
