I ordered the PEDS-18-881C for my 2012 Mazda 3 and was impressed with how smoothly everything went. The unit arrived quickly with free shipping, which was a nice bonus. The ECU was already VIN programmed, so installation was basically plug-and-play. Their customer service was very responsive and helped answer a couple of questions I had before purchasing.
