I was pretty nervous about replacing the ECM on my 2004 Toyota Corolla, but this unit arrived super fast and was exactly as described. Once I got it, installation was straightforward since it was plug-and-play—no complicated programming on my end. The whole process saved me a ton compared to the dealer’s estimate, which was way higher. Plus, the customer service was really helpful and responsive when I had a couple of questions before ordering. My car started right up with no issues, and I’m glad I chose this option.
