The engine stays on all cylinders during cruising and light throttle, where AFM would normally shut half of them down. Installation is plugging it in. Nothing is spliced, flashed or removed from the engine, and the factory system resumes as soon as the module is unplugged.\u003c\/p\u003e\u003ch2\u003eCovered applications\u003c\/h2\u003e\u003cp\u003eEach row below is listed as a 100% fitment match:\u003c\/p\u003e\u003cul\u003e\u003cli\u003e2010–2017 Cadillac Escalade: 6.2L V8\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eFor reference, these are the AFM-equipped GM engine codes that match the years and displacements above:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eL94 (6.2L, 2010–2014, VIN 8th digit \"F\")\u003c\/li\u003e\n\u003cli\u003eL86 (6.2L, 2014–2018, VIN 8th digit \"J\")\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eIn the same trucks and SUVs, GM also built V8s without AFM, for example the 5.3L LH9 (2010–2012 trucks, VIN code P), the 6.0L LY6 and L96 and the 6.2L L9H. Those engines never deactivate cylinders, so the module has nothing to manage on them. If your RPO list shows one of those codes, contact us before ordering.\u003c\/p\u003e\u003cp\u003eAn engine code that is not listed here does not automatically rule the vehicle out, but send us the VIN first so we can check.\u003c\/p\u003e\u003ch2\u003eHow Active Fuel Management operates\u003c\/h2\u003e\u003cp\u003eOn AFM V8 engines, the computer shuts off fuel and holds the valves closed on cylinders 1, 7, 6 and 4 when the load is light, so the engine runs as a V4. It does this through special collapsible lifters on those cylinders, fed by oil-pressure solenoids. When you ask for more power, the lifters lock again and all eight cylinders fire. GM describes this behavior in its service bulletin on AFM and DFM operation.\u003c\/p\u003e\u003cp\u003eGM replaced AFM with Dynamic Fuel Management (DFM) on the 5.3L L84 and 6.2L L87 starting with the 2019 Silverado 1500 and Sierra 1500. The engines covered here use the earlier AFM design.\u003c\/p\u003e\u003ch2\u003eEngine care\u003c\/h2\u003e\u003cp\u003eDisabling cylinder deactivation does not replace normal maintenance. Use the oil grade and change interval GM lists for your engine, watch the oil level between changes, and repair leaks promptly. The valvetrain on these engines depends on clean oil at proper pressure in every mode.\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\u003eThe usual complaints are a drone or shudder in reduced-cylinder mode, a slight hesitation when the engine switches back, and a general wish to keep the valvetrain doing the same thing all the time. With the module installed, the engine stays in full-cylinder mode, so those transitions stop. Expect light-load fuel economy to be closer to an engine without AFM.\u003c\/p\u003e\u003ch2\u003eHow this differs from an AFM delete kit\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\u003eUsing it day to day\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. Plugging it back in restores the all-cylinder mode. Route it so the driver cannot kick it loose.\u003c\/p\u003e\u003ch2\u003eAfter installation\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\u003eHow to confirm your engine code\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eYour model year, model and engine match a row in the table (2010–2017 Cadillac Escalade).\u003c\/li\u003e\n\u003cli\u003eFind your engine code. On GM vehicles before the 2018 model year, the Service Parts Identification label (usually inside the glovebox on these trucks and SUVs) lists the three-character RPO codes, and the engine code starts with L.

GMT900 trucks and SUVs (from the 2007 model year) used Gen IV small-block V8s, while K2XX models (2014-on pickups, 2015-on SUVs) switched to EcoTec3 engines with direct injection.

The L92 (2007–2008 Escalade, Yukon Denali and related models) had no working AFM, and the 2009 flex-fuel L9H had none either. AFM arrived on the 6.2L for 2010 as the L94 in the Escalade and Yukon Denali family. Published application lists show the 2007–2013 Sierra 1500 Denali with the L92\/L9H instead. The 2014-on EcoTec3 6.2L L86 brought AFM to the newer trucks and SUVs.\u003c\/p\u003e\u003ch2\u003eWhere AFM came from\u003c\/h2\u003e\u003cp\u003eGM first sold cylinder deactivation in 1981 with the Cadillac V8-6-4. The modern system was announced in 2003 as Displacement on Demand and reached production on the 2005 Chevrolet TrailBlazer EXT and GMC Envoy XL and XUV with the 5.3L V8, followed by the 5.3L LS4 in the Impala SS, Monte Carlo SS and Pontiac Grand Prix GXP. Renamed Active Fuel Management, it spread across GM's Gen IV and EcoTec3 truck engines. For the 2019 Silverado, GM introduced Dynamic Fuel Management, based on Tula Technology's Dynamic Skip Fire, which can deactivate cylinders individually.\u003c\/p\u003e\u003ch2\u003eWhy oil matters on these engines\u003c\/h2\u003e\u003cp\u003eAFM uses oil pressure as its control signal. A solenoid valve assembly under the intake manifold, in the valley cover, routes oil to collapsible lifters on the deactivating cylinders. Aerated or wrong-viscosity oil slows that signal. Keeping AFM off removes the switching, but every lifter still relies on the oiling system, so stick to the specified oil and intervals.\u003c\/p\u003e\u003ch2\u003eAfter-install checks\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eWarning light appears:\u003c\/strong\u003e Remove the module, scan for codes and email support with the code and VIN.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eMode changes still felt:\u003c\/strong\u003e Re-seat the module and confirm your engine code is on the AFM list for this listing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eShop cannot reach the diagnostic port:\u003c\/strong\u003e Unplug the module for the visit and refit it afterwards.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eLifter noise or misfire codes:\u003c\/strong\u003e These point to existing engine faults that need diagnosis and repair.\u003c\/p\u003e\u003ch2\u003eEngine code notes\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eL94\u003c\/strong\u003e: 6.2L V8 with variable valve timing and flex-fuel capability, used in Escalade and Yukon Denali models.

Match your exact year and engine to a row before ordering.\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 do I tell which engine my Cadillac Escalade has?\u003c\/h3\u003e\u003cp\u003eCheck the 8th digit of the VIN or the RPO codes on the Service Parts Identification label (QR code on the door-pillar label on 2018 and newer GM models).\u003c\/p\u003e\u003ch3\u003eIs a tune or ECU reflash required?\u003c\/h3\u003e\u003cp\u003eNo. The module plugs into the OBD-II port and does not rewrite the engine computer's software.\u003c\/p\u003e\u003ch3\u003eDo I need it if my engine already has an AFM delete?\u003c\/h3\u003e\u003cp\u003eNo. An engine with the AFM hardware removed and a matching tune no longer deactivates cylinders, so the module has nothing to manage.\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. Keeping all cylinders active gives up part of that, depending on how you drive.\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\u003eDoes it work on 2019 and newer trucks with Dynamic Fuel Management?\u003c\/h3\u003e\u003cp\u003eOnly the vehicles and engines in this listing's fitment table are covered. 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\u003ch2\u003eOrdering details\u003c\/h2\u003e\u003cp\u003eShipping is free to the contiguous US.
