The 6.2L GM engine with a Displacement on Demand (DoD) delete, often referred to as Active Fuel Management (AFM) delete, involves modifying the engine to disable the system designed to shut off half of the engine’s cylinders under light-load conditions to improve fuel efficiency. This modification is popular among enthusiasts and owners of vehicles equipped with the 6.2L engine who are looking to increase performance, reliability, and possibly prevent common issues associated with the DoD/AFM system. Here’s how the DoD delete impacts the same models mentioned previously:
A DOD (Displacement on Demand), also known as Active Fuel Management (AFM) in General Motors’ vehicles, is a technology designed to improve fuel efficiency and reduce emissions by deactivating a portion of the engine’s cylinders under certain driving conditions, typically during light load situations. However, some vehicle owners and technicians prefer to delete or disable this feature for various reasons. This process is referred to as a DOD Delete or AFM Delete. Here’s a comprehensive overview:
What is a DOD Delete?
Components Involved in a DOD Delete:
Common Reasons for DOD Delete:
Increased Reliability: Earlier models with DOD/AFM were particularly prone to issues such as lifter failures or excessive oil consumption. Removing the system can lead to a more reliable engine lifespan.
Consistent Performance: Drivers can enjoy the consistent power and torque of a full V8 engine without the transition between different modes, which can sometimes be felt as slight hesitation or roughness.
Oil Consumption: Some DOD/AFM-equipped engines are known to consume more oil, especially when the system is engaging and disengaging. A DOD Delete can mitigate this issue.
Sound: Enthusiasts often prefer the sound of a full V8 engine over one with active cylinder deactivation.
Customization and Control: A DOD Delete gives more control back to the driver and mechanic, allowing for more traditional diagnostics and tuning.
