Important Installation Notes

After purchasing, please provide your VIN so we can program the ECM before shipping. This ensures a perfect match for your vehicle’s computer system. Please note that some vehicles may require relearns or setup procedures after installation (e.g., injector, crankshaft variation). It is the buyer’s responsibility to perform these procedures using GM systems like Tis2web/Techline Connect.

This ECM module is designed for plug-and-play ease, but it’s essential to follow proper installation and programming procedures to avoid any issues. If you’re not comfortable with DIY installation, consult a professional mechanic or the dealership for assistance.
