Expert Insight: Why VIN Programming is Critical
Many people assume you can just swap an ECM from one car to another. This is a critical mistake. The ECM is not just a part; it’s the brain that communicates with your engine, transmission, anti-lock brakes, and even the security system. Flashing it with your specific VIN ensures it has the correct software for your car’s options and immobilizer system. Skipping this step will result in a no-start condition and communication errors. Our service handles this complex process for you, turning a difficult electronic repair into a simple component replacement.
This 2005-2008 Buick Allure ECM is also a direct replacement for service numbers 12581144, 12588472, and 19260507, making it a versatile solution for a range of GM vehicles. Take control of your repair and restore your vehicle’s reliability today.
Frequently Asked Questions
Do I need to do any programming myself?

What if my original part number is different?
Please check the list of compatible service numbers (12581144, 12588472, 12592124, 19260507) and the fitment chart in this listing. As long as your vehicle is listed, this ECM will be programmed to work perfectly, regardless of which of these part numbers was originally installed.
