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 replacing the ECM on my 2012 Jeep Wrangler, but this unit made the process so much easier than I expected. It came fully programmed with my VIN, so I didn’t have to deal with any complicated setup or tuning. The install was straightforward — literally plug and play, which saved me a ton of time and hassle. Shipping arrived quicker than promised, and when I had a couple of questions, their tech support was really helpful and knowledgeable. Now my Jeep runs smoother than ever, and I’m very impressed with the quality of this ECM.
