If the name seems familiar to you, that’s because Tula Technology and Delphi Technologies are the companies that developed Dynamic Skip Fire Cylinder Deactivation for General Motors. The biggest of the Big Three in Detroit has 5.3- and 6.2-liter V8 engines that can switch through 17 cylinder-firing regimes in order to save fuel or provide max get-up-and-go.
An evolution of Active Fuel Management, which alternates between eight- and four-cylinder modes, Dynamic Fuel Management even can operate in two-cylinder mode on the highway when the engine load is at its lowest. Customers who don’t care about saving gasoline can always get an OBD-II disabler that instantly defeats the AFM and DFM systems.
