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 about ordering an ECM online, but this unit for my 2012 Lexus IS350C arrived surprisingly fast and ready to install. The VIN was already programmed, which saved me a ton of hassle and trips to the dealership. Swapping it out was straightforward — literally plug and play with no extra steps. After installation, my car fired right up with no warning lights or issues, just like new. It’s clear this is a high-quality part, and the support team was quick to answer a couple of questions I had before buying. Overall, a stress-free experience that got my Lexus back on the road in no time!
