Injector & ignition pulse simulation
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 — $300 CAD / $215 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.

Sean Morris –
The ECM arrived quickly and was exactly as described, already programmed to my vehicle’s VIN which saved me a ton of time. Installation was straightforward with no complicated steps—just plugged it in and the Suburban fired up perfectly. It performed flawlessly right out of the box, and I appreciated the helpful customer service when I had a quick question. Definitely a hassle-free upgrade for anyone needing a replacement.
