상품 특징

• 🚗 Does Your V8 Feel Different Than It Should? Feel shudder, hesitation, lag, or constant switching while cruising? This AFM/DFM Disabler helps reduce cylinder transitions and keeps engine response smoother and more predictable during daily driving.
• 🛠️ Why Try This Before Major Repairs? Many drivers choose this Active Fuel Management Disabler before considering expensive AFM delete kits or repairs. Frequent cylinder switching is commonly discussed alongside L87 concerns, lifter wear, oil consumption, and carbon buildup.
• 🧠 What Do I Actually Change? Nothing permanent. Unlike mechanical AFM delete solutions, this GM AFM disabler works externally through OBD2 communication to help prevent AFM/DFM activation without rewriting ECU software.
• 🔋 Will I Drain Your Battery? Built for long-term connection with standby current below 20mA and operating temperatures from −40°C to 80°C. Designed for everyday driving without unnecessary battery consumption.
• 🎛️ Can You Decide When I Work? Yes. Plug into OBD2, press and hold the rear button until LED lights up, then use the built-in switch to control operation. Available in lightweight ABS or premium aluminum housing.
• 🧩 Driving a Silverado 5.3? Compatible with select V6/V8 applications including popular AFM-equipped models such as Silverado 1500 5.3L and expanded model-year coverage. Please verify fitment before ordering.
