It arrived two days later, we swapped it in the parking lot in under 30 minutes, performed the key relearn, and the van has been running flawlessly ever since.

Frequently Asked Questions
Do I need to do any programming myself?
No. We handle all the programming for you before the item ships. We use your vehicle’s VIN to load the latest GM calibration files, so it’s ready for installation when it arrives.
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, you will need to send us your 17-digit VIN. We cannot ship your order until we receive this information, as it is essential for the programming process.
Is this a difficult part to install?
The physical installation is typically straightforward, involving disconnecting the battery, unplugging the electrical connectors, and removing a few mounting bolts. After installation, you may need to perform a simple security relearn procedure (often called a ‘key relearn’), which can usually be done without special tools. Instructions are widely available online for this process.
How do I know if my original ECM is failing?
Common signs include a check engine light that won’t go away, engine stalling or misfiring, poor fuel mileage, shifting problems in automatic transmissions, or a complete no-start condition where the engine cranks but won’t fire up.
Which vehicles will this ECM fit?
This ECM fits a wide range of GM vehicles, including the 2016 Savana/Express 2500 & 3500 vans, 2012-2016 Silverado/Sierra 2500 & 3500 pickups with the 6.0L engine, and various cars like the Chevy Cruze, Sonic, Volt, and Buick Encore. Please see the full fitment list for details.
