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.

Swapping out the ECM on my 2020 Jeep Wrangler was something I was dreading, but this unit made the whole process surprisingly smooth. It arrived quickly and was already VIN programmed, so I just plugged it in and fired up the engine right away. I appreciated not having to mess with any complicated setups or coding on my own. The Jeep runs perfectly now, no error lights or hiccups, and I’m confident it’s as reliable as the original part. Definitely took a load off my mind and saved me a trip to the dealership.
