Restore Peak Performance to Your GM Vehicle
Is your 2015-2016 Chevrolet Tahoe, Silverado, or other compatible GM vehicle suffering from perplexing issues like a persistent check engine light, stalling, rough idling, or a sudden drop in fuel economy? These are classic signs of a failing Engine Control Module (ECM), the central computer that governs your engine’s most critical functions. A faulty ECM can disrupt everything from fuel injection and ignition timing to transmission shifting, leaving you with an unreliable and inefficient vehicle. This replacement Engine Control Module is the definitive solution to restore your vehicle’s original performance and dependability.
The Simple, Dealer-Free Solution: Pre-Programmed for Your Vehicle
One of the biggest hurdles in replacing an ECM is the need for expensive and time-consuming programming at a dealership. We eliminate that step entirely. When you purchase this module, we use the Vehicle Identification Number (VIN) you provide to flash it with the latest, most stable software updates directly from GM. This ensures that the module is a perfect match for your vehicle’s specific configuration, including its engine, transmission, and factory options. The result is a straightforward installation process that gets you back on the road faster. This is not just a replacement part; it’s a fully integrated solution tailored for your 2015-2016 Tahoe Engine Control Module and a wide range of other GM models.
From the Diagnostic Bay
We had a 2015 Silverado 1500 come in with a frustrating, intermittent no-start condition. The owner had already replaced the battery and starter to no avail. After running diagnostics, we found communication errors pointing directly to the ECM. Instead of a costly new unit from the dealer, we installed one of our VIN-programmed modules. The truck fired up on the first try and ran smoother than it had in years. The customer was thrilled to have a reliable truck again without the massive dealership bill.

Frequently Asked Questions
Is this ECM truly plug-and-play?
Almost. Because we program the module to your specific VIN, it will have the correct software for your engine and transmission. However, in most GM vehicles, you will need to perform a simple Security Relearn procedure after installation. This can typically be done without special tools and involves a sequence of key cycles. In some cases, a Crankshaft Variation (CASE) Relearn may also be required, which needs a capable scan tool.
How do I provide my VIN number?
After you complete your purchase, we will contact you for your vehicle’s 17-digit VIN. You can also add it to the notes section during checkout. We cannot program and ship the module without this information, so please provide it promptly to avoid delays.
Will this fix my specific problem or check engine light?
This module will resolve any issues directly caused by a faulty ECM. If your check engine light is on due to a failed computer, this will correct it. However, if the light is caused by a different faulty component (like an oxygen sensor or ignition coil), you will still need to address that separate issue. Proper diagnosis is key.
Do I need to return my old ECM?
No, there is no core charge or requirement to return your old module for this particular part. You can keep your old one or recycle it locally.
What if my original part number is not on your list?
The provided list covers the most common compatible part numbers. If your number is different, please contact us with your vehicle’s VIN. We can verify compatibility and ensure you receive the correct module for your application.
