The module connects at the OBD-II port and keeps GM's cylinder deactivation from switching on, which means steady all-cylinder operation instead of repeated changes between full and partial mode.

The engine computer decides when to switch based on load, speed and other inputs. This module works through the OBD-II port to keep the computer from choosing the reduced mode.\u003c\/p\u003e\u003ch2\u003eThe first drive\u003c\/h2\u003e\u003cp\u003eDrive at a steady cruise on a light throttle, where AFM used to switch modes. The engine should now stay on all cylinders, so the subtle shudder, drone or hesitation that came with each change should be gone. If your dash shows instant fuel economy, expect the light-cruise numbers to read a little lower than before, since that is exactly where cylinder deactivation saved fuel.\u003c\/p\u003e\u003ch2\u003eOil and maintenance\u003c\/h2\u003e\u003cp\u003eOil level and quality are worth watching on any AFM engine, because the deactivation hardware is hydraulic. Check the dipstick at fuel stops on high-mileage engines, follow GM's specified oil grade, and address oil-pressure warnings immediately. None of that changes with the module installed.\u003c\/p\u003e\u003ch2\u003ePlug-in module vs. a mechanical AFM delete\u003c\/h2\u003e\u003cp\u003eOwners who want AFM gone for good sometimes go the mechanical route: non-AFM lifters, a matching camshaft and a retune. That is a large job and it is permanent. A tuner can also disable AFM in the engine computer. The plug-in module sits at the other end of the scale: no parts replaced, no software rewritten, and back to factory with one pull. It is meant for engines that run well and simply should not switch modes.\u003c\/p\u003e\u003ch2\u003eBefore installing\u003c\/h2\u003e\u003cp\u003eScan for stored codes before you plug it in. Misfire codes on the deactivation cylinders, an AFM solenoid circuit code, or a lifter noise are signs of an existing problem that should be repaired first. The module is meant for a healthy engine where you simply do not want cylinder deactivation.\u003c\/p\u003e\u003ch2\u003eWhy people turn AFM off\u003c\/h2\u003e\u003cp\u003eA Suzuki XL-7 with AFM switches modes many times on a typical drive. Some owners never notice; others feel it every time. If you are in the second group, or you tow and want steady behavior, keeping all cylinders active is the simplest answer. Fuel use at light cruise will usually rise a little, since that is where AFM saves fuel.\u003c\/p\u003e\u003ch2\u003eScan tools and inspections\u003c\/h2\u003e\u003cp\u003eThe module uses the OBD-II port, so it has to come out whenever a technician or an inspection station needs the port.

Its solenoids send pressurized oil to special hydraulic roller lifters (supplied by Eaton and Delphi) on the deactivating cylinders, which then stop opening the valves.

The LGX (2016-on Camaro) and the LGZ (2017-on Colorado and Canyon) both use direct injection, variable valve timing and Active Fuel Management, running on four cylinders at light load (cylinders 2 and 5 are shut down on the LGX). The LFX, used in the 2015–2016 Colorado and Canyon, and the LFY in the 2018 Traverse and Enclave do not have AFM.

DFM on the 2019-on Silverado 1500 and Sierra 1500 (5.3L L84, 6.2L L87) is a different system, so do not assume coverage outside the table.\u003c\/p\u003e\u003ch3\u003eDoes it change anything when towing?\u003c\/h3\u003e\u003cp\u003eUnder heavy load, such as towing up a grade, AFM already keeps all cylinders running. The difference shows up during lighter cruising between climbs, where the engine no longer drops cylinders.\u003c\/p\u003e\u003ch3\u003eWill it fix lifter noise or misfires?\u003c\/h3\u003e\u003cp\u003eNo. Those are mechanical or electrical faults that need their own diagnosis and repair.\u003c\/p\u003e\u003ch3\u003eWill it add horsepower?\u003c\/h3\u003e\u003cp\u003eNo. It keeps all cylinders active; it does not change the engine tune.\u003c\/p\u003e\u003ch3\u003eHow much fuel does AFM save?\u003c\/h3\u003e\u003cp\u003eEPA-test estimates published for GM's system are about 5.5–7.5%, with the benefit coming from light-load cruising.
