🚗 Stop Constant Cylinder Switching
GM's Active Fuel Management (AFM) and Dynamic Fuel Management (DFM) systems are designed to improve fuel economy by switching between full-cylinder and reduced-cylinder operation during certain driving conditions.
Many drivers prefer to disable this feature because they dislike:
✔ Frequent switching between cylinder modes
✔ Changes in engine feel
✔ Inconsistent throttle response
✔ Reduced exhaust sound
NexDrive™ helps keep your engine operating in full-cylinder mode whenever the device is connected.

🔒 No ECU Flashing or Permanent Changes
Unlike custom tuning or ECU reprogramming, NexDrive™ does not permanently alter your vehicle's factory software.
Simply unplug the device whenever you wish to return the vehicle to its original operation.
✔ No permanent programming
✔ No software installation
✔ Fully reversible
✔ Leaves factory calibration unchanged

With AFM/DFM disabled while the device is connected, many drivers appreciate:

Driving characteristics may vary depending on vehicle model and conditions.
