Remanufactured GM ECM - VIN Programmed - Ready to Install Condition: Remanufactured unit. Global A module cloning: This module may be eligible for cloning or data transfer when the original module can be read. Cloning availability depends on the original module condition, service number, VIN/application, and programming workflow. This remanufactured GM engine control module is prepared for VIN-based programming and application review. The application guide below lists compatible GM vehicles and related service/module numbers in a normalized year, make, and model format. GM service numbers and module labels may cross-reference multiple vehicle applications. We keep the service/module number coverage visible, then review the final programming details against your VIN and original module information before release.

GM Module Cloning Services Global A GM modules such as E38, E39, E67, E83, E92, and later GM BCM applications may also be candidates for cloning or data transfer when the original module can be read. Important fitment and programming notice Please verify your original module number before purchase and provide your VIN so programming and fitment can be reviewed. When available, include the original module number or software ID, a clear module label photo, and photos of the original unit / connector side. Many GM vehicles require one or more post-install procedures such as theft-deterrent / security relearn, crankshaft variation learn, idle or throttle learn, transmission adaptive / fast learn, or module setup with a capable scan tool. Required relearns vary by vehicle, module type, and calibration. Our online catalog is an application guide, not an automatic fitment guarantee. Fitment is reviewed during programming, but the customer is responsible for confirming they are purchasing the correct part for their vehicle. Once programming, calibration retrieval, or supplier processing has started, related service costs may apply if the supplied vehicle or module information is incorrect.
