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 was really impressed with how straightforward the installation was for this 2012 Chrysler 300 ECM. It arrived quickly and came already programmed to my VIN, which saved me a ton of hassle. Once I plugged it in, everything fired right up without a hitch—no extra tweaking needed. The engine runs smoothly now, and I haven’t noticed any glitches since swapping it out. I also appreciated the quick responses from their support team when I had a couple of questions about the process. Definitely a stress-free upgrade that got my car back on the road fast.

After swapping it in, the car fired up immediately with no warning lights or issues. Overall, a hassle-free solution that saved me a lot of downtime and money.
