AFM Disabler questions
What does an AFM/DFM disabler do?
GM's Active Fuel Management (AFM) and Dynamic Fuel Management (DFM) shut off cylinders under light load to save fuel. The disabler plugs into the OBD-II port and keeps the engine in full-cylinder mode (V8 stays V8, V6 stays V6), so you avoid the constant switching many owners link to lifter wear, oil consumption, shudder and hesitation.
Do I need to reprogram or tune the ECU?
No. There is no tuning, no software and no tools. Plug it in, wait for the indicator light, and drive. Unplug it and the vehicle returns to factory behavior.
Will it drain my battery?
The 2026 edition uses smart power management and goes to sleep when the engine is off, so it can stay plugged in. The previous Auto Start/Stop setting is also remembered.
Which vehicles does it fit?
Most GM trucks, SUVs and cars with V6 / V8 engines equipped with AFM or DFM from roughly 2005 to 2024 — Silverado, Sierra, Tahoe, Suburban, Yukon, Escalade, Camaro, Colorado, Canyon and more. See the full compatibility list, or send us your VIN to confirm.
Is it the same as an AFM delete kit?
No. A delete kit replaces lifters, the camshaft and valley plate and requires an ECU re-flash — a major, permanent engine job. The disabler is a plug-in electronic solution that leaves the engine untouched and is fully reversible.
What is the MOQ for wholesale and private label?
Samples and small trial orders are welcome for neutral packaging. Custom logo, color and packaging start from 1,000 pcs. Contact us with your quantity for tiered pricing.
Is it legal to use?
Rules on modifying emission-related systems differ by country and state. The disabler does not alter ECU software, but resellers and end users are responsible for checking compliance with local regulations in their market.
Can I order samples before a bulk order?
Yes. Neutral-packaged samples of the AFM/DFM Disabler and every OBD2 model are available so you can test fitment, apps and quality. Sample cost and shipping are quoted based on your destination.
Which OBD2 adapters work with iPhone?
Choose a WiFi model (KS-8804, KS-8805, KS-8806), the DC24K WiFi 6 + Bluetooth adapter (KS-8810) or a DC24K Bluetooth 5.x model. Older classic-Bluetooth-only adapters are recommended for Android and Windows users.
What certificates do your products have?
The OBD2 range carries CE, RoHS, UKCA and FCC documentation with test reports, and several housings are protected by utility-model and design patents. Certificates are available on request for marketplace and customs compliance.
Can you put my logo on the product and packaging?
Yes. Housing color (from the factory color card), retail box, stickers and manuals can all carry your logo and brand information. Custom-branded orders start from 1,000 pcs per model.
How are orders packed and shipped?
Each unit comes in a retail color box. Dongles are packed 250 pcs per export carton and handheld scanners 50 pcs per carton (50 × 31 × 35 cm). We ship by express, air or sea depending on order size and your timeline.
