Does GM still have AFM?
General Motors is now building 2021 Chevy Silverado 1500 and 2021 GMC Sierra 1500 pickup trucks without Active Fuel Management (AFM) and Dynamic Fuel Management (DFM) technologies due to the ongoing global microchip shortage. The change is expected to continue through the 2021 model year.
Does the 2021 Trail Boss have AFM?
DFM does remain with the pairing of 5.3-liter V8 and 10-speed automatic that comes standard on the LT Trail Boss and High Country. “Due to the micro controller shortage, the components that control AFM/DFM in the engine control module (ECM) have been removed,” GM spokesperson Michelle Malcho told Autoblog.
What does Active Fuel Management ( AFM ) do?
Active Fuel Management (AFM), otherwise known as Cylinder Deactivation is a General Motors engine technology that shuts down half of the engine’s cylinders in light driving conditions to improve fuel economy.
How to disable Active Fuel Management on GM engine?
Should you delete Active Fuel Management on GM engine? There are two ways to disable active fuel management on a GM vehicle, but first you have to determine whether your engine is a candidate for the delete or disable procedure.
How does Active Fuel Management affect fuel efficiency?
This reduces engine efficiency, which means less than optimal fuel economy. Active Fuel Management saves fuel by using only half of the engine’s cylinders during some driving situations – such as highway cruising — and then seamlessly reactivates the other cylinders when a driver demands more power for acceleration, climbing a grade or hauling.
Where is the oil filter in Active Fuel Management?
To help control contamination within the active fuel management hydraulic system, a small replaceable oil filter is located in the valve lifter oil manifold oil inlet passage. The oil pressure sensor monitors engine oil pressure and provides information to the ECM.
How does Active Fuel Management ( AFM ) work?
AFM was designed to provide maximum fuel economy under light load driving conditions by deactivating the lifters on specific cylinders. On V8 engines, half of the cylinders are deactivated and on V6 engines, two of the cylinders are deactivated.
Should you delete Active Fuel Management on GM engine? There are two ways to disable active fuel management on a GM vehicle, but first you have to determine whether your engine is a candidate for the delete or disable procedure.
Which is the best software for fuel management?
Gasboy’s services include its EKOS (Energy Knowledge Operating System) software, which tracks transactions and handles custom reporting on data from multiple systems. They also offer a wide array of fuel island and vehicle tracking software systems, each providing reliable comprehensive services.
Are there any diesel retrofit programs in California?
Thanks in part to the Carl Moyer Program, California is a large market for retrofit technologies. According to the Manufacturers of Emission Controls Association, over 55,000 diesel particulate filters have been installed on diesel vehicles and equipment in California.
