Its job is to keep the engine running on all cylinders instead of dropping into the reduced-cylinder mode that GM's Active Fuel Management uses at light load. 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\u003eWhat it fits\u003c\/h2\u003e\u003cp\u003eEach row below is listed as a 100% fitment match:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e2010–2015 Chevrolet Camaro: 6.2L V8\u003c\/li\u003e\n\u003cli\u003e2016–2018 Chevrolet Camaro: 6.2L V8 \/ 3.6L V6\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eAFM-equipped engine codes that GM used in these years and sizes:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eL99 (6.2L, 2010–2015, VIN 8th digit \"J\")\u003c\/li\u003e\n\u003cli\u003eLT1 (6.2L, 2016–2018, VIN 8th digit \"7\")\u003c\/li\u003e\n\u003c\/ul\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\u003eWhat AFM does on these engines\u003c\/h2\u003e\u003cp\u003eWhen cruising at steady speed, an AFM V8 drops to four cylinders. Cylinders 1, 7, 6 and 4 have two-stage lifters that the engine computer can switch with oil pressure; once switched, those valves stay shut and the injectors stop firing. The switch back to eight cylinders happens whenever more torque is needed.\u003c\/p\u003e\u003ch2\u003eWhy owners disable it\u003c\/h2\u003e\u003cp\u003eA Chevrolet Camaro 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\u003eAfter installation\u003c\/h2\u003e\u003cp\u003eExpect steadier behavior at part throttle and no change at wide-open throttle. Towing and hill climbing were already mostly done on all cylinders, so the biggest change is during relaxed cruising. Average fuel economy may drop slightly depending on how much of your driving is light-load highway time.\u003c\/p\u003e\u003ch2\u003eCheck the engine first\u003c\/h2\u003e\u003cp\u003eKeep the oil at the correct level and grade before and after installation. AFM lifters and their solenoids are oil-pressure operated, so an engine that is low on oil or running the wrong grade should be sorted out first. The module stops the switching, but it is not a substitute for maintenance or for repairing an engine that already has a fault.\u003c\/p\u003e\u003ch2\u003eKeep up with oil changes\u003c\/h2\u003e\u003cp\u003eAFM lifters and the solenoids that control them run on engine oil pressure. Keeping the oil at the right level, using the grade GM specifies on the oil filler cap or in the owner's manual, and changing it on schedule matters whether or not AFM is active. The module changes when cylinders deactivate; it does not change the oiling system.\u003c\/p\u003e\u003ch2\u003eScan tools and inspections\u003c\/h2\u003e\u003cp\u003eLeave it in the port for everyday driving. When the vehicle goes in for service or an emissions check, remove it so the shop has normal access to the diagnostic connector, then reinstall it.\u003c\/p\u003e\u003ch2\u003eOther ways owners disable AFM\u003c\/h2\u003e\u003cp\u003eThere are three common ways to stop cylinder deactivation on GM engines: a plug-in module like this one, a custom tune that turns AFM off in the engine computer, or a mechanical delete that replaces the AFM lifters and related hardware and then needs a tune to match. The module is the only one of the three that needs no tools and no engine-computer changes, and it is the only one you can undo by unplugging it. It does not replace failed lifters; if hardware is already damaged, the repair comes first.\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 (2010–2018 Chevrolet Camaro).\u003c\/li\u003e\n\u003cli\u003eLook up the engine RPO code.

It plugs into the OBD-II port under the dash. There is no wiring or splicing.\u003c\/p\u003e\u003ch3\u003eWhich Chevrolet Camaro years and engines does it fit?\u003c\/h3\u003e\u003cp\u003eThe fitment table lists Chevrolet Camaro 2010–2018 with 3.6L V6, 6.2L V8. Match your exact year and engine to a row before ordering.\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\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\u003eDo I need to remove it for an emissions test or scan tool?\u003c\/h3\u003e\u003cp\u003eYes. It uses the diagnostic port, so unplug it while the port is needed and plug it back in afterwards.\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\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\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\u003ch3\u003eCan I go back to factory AFM?\u003c\/h3\u003e\u003cp\u003eYes. Unplug the module and the factory cylinder-deactivation strategy works again.\u003c\/p\u003e\u003ch2\u003eWarranty and returns\u003c\/h2\u003e\u003cp\u003eWe ship free within the contiguous United States (1–2 business days to dispatch, roughly 3–4 business days in transit). If it turns out to be the wrong part, request a return authorization within 45 days; returns carry a 20% restocking fee and return postage is on the buyer. Coverage is a 3-year limited warranty.
