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.

Ethan Sanders –
Swapped out my old ECU with this one and it fired right up—super quick delivery and zero hassle installation.
This ECM fit perfectly and worked flawlessly from day one; really impressed with how straightforward the whole process was.
Got my Jeep running smoothly again thanks to this plug-and-play unit, plus the support team was quick to answer all my questions.
Installation was a breeze and the programmed ECU matched my VIN perfectly—definitely worth every penny.
Fast shipping and an exact fit for my 3.6L Grand Cherokee, made what could’ve been a headache super easy.
