Yes, most ECMs require programming to match your vehicle’s VIN and security system. This should be done by a qualified technician or Mazda dealer. The programming process typically takes 1-2 hours.
Common symptoms include engine not starting, rough idle, poor fuel economy, check engine light, or multiple warning lights on the dashboard. A diagnostic scan can confirm ECM-related fault codes.
No, this specific ECM is calibrated for automatic transmission only. Manual transmission vehicles require a different ECM with appropriate programming for clutch and transmission control.
You receive the complete engine control module as shown. The ECM comes with our 90-day warranty but does not include programming services or installation hardware.
While the physical installation is straightforward, the ECM requires professional programming to function properly. We recommend having it installed and programmed by a qualified automotive technician.

Great experience at 603 Auto Salvage! ⭐️ The owner and employee were both extremely helpful and easy to work with. I was able to find everything I needed in one stop — about seven different items — which saved me a lot of time and hassle. Good selection, fair pricing, and friendly service. Definitely recommend checking them out if you're looking for parts. I’ll be back again! 👍🔧🚗

Highly recommend if you want knowledgeable people who actually care about helping you. Kristy Thanks Guys!
Drove from Connecticut to get here. Had parts for a relatively rare car that dozens of other places didn't have. I got a hood, fender and bumper cover that were in near mint condition for a fifteen year old car. They pulled all the parts for me and had everything ready within an hour. Very reasonably priced. Highly recommend
