If cloning is not selected, the ECU will be VIN programmed, and a key relearn will be required after installation.

Swapped out my old ECM with this one and it fired right up—super easy install and no hiccups. Arrived quicker than I expected too!

I was pleasantly surprised by how quickly this ECM arrived and how seamlessly it fit into my 2007 Buick Lucerne. The VIN programming was spot on, so there was no hassle with compatibility or reprogramming on my end. Installation was straightforward, truly a plug-and-play experience, and my car has been running perfectly since. The support team was also helpful when I had a quick question, which made the whole process much smoother.
