Powerstay Start/Stop And AFM Disabler Gm/Ford

The HYPERTECH Powerstay Start/Stop and AFM Disabler for GM and Ford vehicles is a computer module designed to eliminate automatic engine shut-down cycles during operation. This module is particularly beneficial for drivers who prefer reliability and performance consistency over factory fuel-saving algorithms.

By disabling both the Active Fuel Management (AFM) system and the Start/Stop automatic shut-down feature, the Powerstay restores traditional engine operation characteristics. It functions as an OEM-compatible engine computer interface, intercepting AFM and Start/Stop commands without requiring permanent modifications to the vehicle.

This solution is ideal for fleet operators, work vehicle owners, and driving enthusiasts who prioritize engine longevity and predictable performance. It is especially valuable for those engaged in towing, frequent stop-and-go driving, or high-demand scenarios, as it helps eliminate wear patterns associated with repeated engine shutdowns.
