Leasing a car can be an attractive option for those who want to drive a new vehicle without the long-term commitment of ownership. However, as a lessee, you may be limited in what modifications you can make to the vehicle. One common modification that some drivers consider is using a RANGE GM AFM DISABLER RED to disable the Active Fuel Management (AFM) system in their leased vehicle. But is it allowed?

Understanding the AFM System

Before we dive into whether using a RANGE GM AFM DISABLER RED is allowed on a leased vehicle, let's take a closer look at what the AFM system is and why someone might want to disable it.

The AFM system is a feature found in some General Motors (GM) vehicles that helps to improve fuel efficiency by deactivating half of the engine's cylinders when they are not needed. For example, when driving on a highway at a steady speed, the engine may only need four of its eight cylinders to maintain that speed. By deactivating the other four cylinders, the engine uses less fuel and produces fewer emissions.

While this system can be beneficial for fuel economy, some drivers find that it can cause issues with their engine. The constant switching between four and eight cylinders can lead to excessive oil consumption, premature wear on engine parts, and a rough or shuddering idle.

What is a RANGE GM AFM DISABLER RED?

A RANGE GM AFM DISABLER RED is a device that plugs into the diagnostic port of a GM vehicle and disables the AFM system. It essentially tricks the vehicle's computer into thinking that the engine is always under heavy load, preventing it from deactivating cylinders.

The device can be a useful solution for those experiencing issues with their AFM system. By disabling the system, drivers can potentially avoid costly repairs and improve the overall performance of their engine.

Using a RANGE GM AFM DISABLER RED on a Leased Vehicle

So, can you use a RANGE GM AFM DISABLER RED on a leased vehicle? The short answer is that it depends on your lease agreement.

Most lease agreements prohibit lessees from making any modifications to the vehicle without the lessor's permission. This includes modifications to the engine, exhaust, suspension, and more. If you use a RANGE GM AFM DISABLER RED on a leased vehicle without permission, you may be in violation of your lease agreement and could face penalties or fees.

Before making any modifications to your leased vehicle, it's important to review your lease agreement and speak with your lessor. Some lessors may allow certain modifications, while others may not. If you're unsure, it's best to err on the side of caution and avoid making any modifications that could potentially violate your lease agreement.

Conclusion

In summary, using a RANGE GM AFM DISABLER RED can be a useful solution for those experiencing issues with their AFM system. However, if you're leasing a vehicle, you should review your lease agreement and speak with your lessor before making any modifications. Violating your lease agreement can result in penalties or fees, so it's important to understand what modifications are allowed and what modifications are prohibited.
