Active Cylinder

The cylinder-on-demand system is designed to improve fuel efficiency by deactivating half of the engine’s cylinders during low and medium loads. This allows the vehicle to save fuel during coasting or lower acceleration situations. However, when rapid acceleration is required, the system quickly reactivates all cylinders for maximum power.

If you’re looking to disable this feature and have your vehicle run on all four cylinders at all times, the AutoHex module can achieve that. This modification can provide a more consistent driving experience, especially for those who prefer immediate power delivery without the variable cylinder activation.
