Frequently Asked Questions
How do I provide my VIN number?
After you complete your purchase, you will receive an email with instructions on where to send your VIN. You can also add it to the ‘notes’ section during checkout. We cannot program or ship the module without your vehicle’s VIN.
Will I need to do anything after installing the ECM?
In most cases, the unit is plug-and-play. However, some GM vehicles require a simple security relearn procedure, also known as a key relearn. This can typically be done yourself in about 15-20 minutes without any special tools. We include instructions for this common procedure.
Is this the correct part for my van?
This ECM fits the 2016 GMC Savana 2500 with the 4.8L and 6.0L engines. The best way to confirm is to match the part number from your old unit to one of the numbers listed, such as 12668991. Providing us with your VIN guarantees we will send you the correctly programmed part for your exact vehicle.
What does ‘programmed’ actually mean?
Programming, or ‘flashing’, involves loading the vehicle-specific software onto the ECM using your VIN. This data controls engine timing, fuel delivery, transmission shifting, and emissions systems. Without correct programming, the vehicle will not start or run properly.
How long does the programming and shipping process take?
Once we receive your VIN, programming is typically completed within one business day. The total time to receive your part will depend on the shipping method you select at checkout.
