How Qzucar AFM Disable Device works
The Qzucar AFM Disable Device seamlessly integrates with your vehicle’s On-Board Diagnostics (OBD-II) port, functioning as an intelligent override to the Active Fuel Management (AFM) system. Once connected, it blocks the activation of AFM, ensuring that the engine runs on all cylinders continuously, without the intermittent deactivation that typically occurs. This results in consistent power delivery, improved throttle response, and an overall smoother driving experience. The device is designed for effortless installation, requiring no modifications to your vehicle’s engine management system. It provides an efficient, non-invasive solution to enhance engine performance without the complexity of professional tuning.
