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 installed the 2018 Chevrolet Silverado 6.0L ECM on my truck last week, and it worked perfectly right out of the box. The VIN was already programmed, so there was no hassle on my end, and the plug-and-play design made the swap quick and straightforward. Shipping was surprisingly fast, and I appreciated the clear instructions that came with it. Highly recommend for anyone needing a reliable replacement!

I was a bit nervous about swapping out the ECM on my 2018 Silverado, but this unit made the whole process way easier than I expected. It came already VIN programmed, so all I had to do was plug it in and go. The truck fired up instantly, and everything runs smoothly now—no error codes or hiccups. Shipping was quick, and the customer support was super helpful when I had a couple of questions before ordering. Overall, a solid buy that saved me a lot of time and hassle. Highly recommended if you want a straightforward fix.
