I recently replaced the ECM on my 2020 Chevrolet Traverse with this VIN-programmed unit, and I couldn’t be happier with how smooth everything went. The module arrived sooner than I expected, and installation was truly hassle-free—just plugged it in, and it fired right up. It’s impressive how precise the programming was; there were no error codes or weird issues afterward. I also appreciated the helpful guidance from their support team when I had a couple of questions during setup. Overall, this was a solid buy that saved me a lot of time and stress.
