I recently purchased the 89661-01140 ECU for my 2004 Toyota Corolla, and I couldn’t be happier with the experience. The unit arrived much quicker than I expected, and the free shipping was a nice bonus. What really stood out was how smoothly the plug-and-play setup went—installed it without any issues, and the car fired right up. The quality of the programming is top-notch; no glitches or error codes at all. Overall, this was exactly what my Corolla needed to get back on the road reliably.
