void my warranty?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e Nope. The device is designed to leave no trace. Just unplug it before any dealer visit, and there will be no evidence it was ever installed.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What does the LED light mean?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e When you first plug it in, the light will blink a few times—that means it has power and is connecting to your vehicle. Once it turns a \u003cstrong\u003esolid green\u003c\/strong\u003e, the connection is good and it’s working properly. The green light stays on whenever your vehicle is running.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What will it do to my gas mileage?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e Most users don’t see a noticeable change, and some even see a small improvement—especially in city driving where constant cylinder switching can actually hurt mileage. On pure highway trips, you might see a very slight decrease, but it’s generally minimal.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does it reprogram my ECU?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e Not at all. It doesn’t change or rewrite any of your factory programming. It simply sends a command to the ECU to keep all cylinders active.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Will it pass emissions testing?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e The device itself won’t cause you to fail, but we always recommend removing it before any state emissions test since they usually scan the OBD-II port as part of the inspection.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Will it fix my car if I already have a collapsed lifter?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e Unfortunately, no. A collapsed lifter is a mechanical failure that requires physical repair. Our device is designed to \u003cem\u003eprevent \u003c\/em\u003elifter failure, not fix existing damage.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does it cause issues with the myChevrolet (or myGMC) app?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e No, it works just fine alongside the app.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is there a warranty?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e Yes!

By eliminating the lag when the system switches back from V4 to V8 mode, throttle response feels much sharper and more consistent.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How can I tell if it’s working?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA:\u003c\/strong\u003e A solid green LED light means it’s working. For most pre‑2019 AFM vehicles, you can also watch your dash indicator (it should stay in V8 mode). 2019+ models with DFM don’t have that indicator, so the green light on the device is your confirmation.

AFM\/DFM physically turns off half your cylinders by collapsing lifters, dozens of times per drive. This repeated on\/off slamming causes excessive wear. Our device stops this process entirely, allowing all components to operate in their designed, stable, full-cylinder state. This significantly reduces stress on the valvetrain, helping to prevent lifter collapse, camshaft scoring, and the domino effect of damage that follows.\u003c\/p\u003e","brand":"BlueV8","offers":[{"title":"Default Title","offer_id":47839665127642,"sku":"v8blue","price":0.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0796\/7788\/2586\/files\/blue2.jpg?v=1778762174","url":"https:\/\/www.bluev8.com\/products\/afm-dfm-disabler-for-replacement","provider":"BlueV8","version":"1.0","type":"link"}
