I recently purchased the 23710-CD007 ECM for my 2004 Nissan 350Z, and I’m really impressed with how smoothly everything went. The ECU arrived quickly with free shipping, which was a nice bonus. What stood out the most was that it came VIN programmed, so installation was straightforward — just plug and play with no hassle. The engine runs perfectly, and I haven’t experienced any issues since the swap. Definitely a reliable product from a seller that knows what they’re doing.
