Frequently Asked Questions
What exactly is VIN programming?
VIN programming is the process of loading your vehicle’s specific software onto the ECM. Every vehicle has unique settings based on its engine, transmission, and factory options. By programming the module to your VIN, we ensure it communicates perfectly with all other systems in your truck, just like the original one did.
Is this part truly plug-and-play?
Because we program it to your VIN before shipping, it is designed to be a direct installation. However, some vehicles may require an additional security relearn procedure (like a crankshaft position sensor relearn) which can often be done without special tools. Instructions are widely available online for this simple procedure.
How do I provide my VIN?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as the programming is a critical part of your order.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the old ECM (common codes include P0601, P0602, P0606), then this part is the correct fix. It is essential to properly diagnose your vehicle first to ensure the problem is the ECM and not a sensor or wiring issue.
What if my truck has other modifications?
This ECM is programmed with standard factory GM calibrations. It is designed for vehicles with original factory equipment and is not intended for vehicles with significant performance modifications.
