Injector & ignition pulse simulation
Power, ground, and load-circuit analysis

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.

I was a bit nervous about replacing the ECM on my 2014 Silverado, but this VIN-programmed unit made the process so much easier than I expected. It truly was plug-and-play—no complicated setup or extra tuning required. The shipping was surprisingly quick, and when I had a question, the tech support team was very helpful and patient. After the swap, my truck fired up right away and runs perfectly smooth. Definitely a relief to find a product that works exactly as promised.

The VIN programmed ECM arrived quickly and was exactly as described. Installation was straightforward with no extra programming needed, which saved me a lot of time and hassle. My Silverado is running perfectly now, and I’m really pleased with the quality and fit. The support team was also helpful when I had a couple of quick questions.
