Installation takes seconds — no tools, no tuning, and no permanent changes — and the unit is backed by a patented design with international registration.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this disabler work with my vehicle’s OBD-II port?\u003c\/h3\u003e\n\n\u003cp\u003eThe Pooperws unit intercepts the AFM\/DFM signal through the OBD-II connector and alters the communication so the vehicle maintains full-cylinder operation. It does not reflash or modify the ECU, meaning factory settings remain intact if you unplug the device.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003ePlug into the OBD-II port — instant effect\u003c\/li\u003e\n  \u003cli\u003eNo ECU reflashing or permanent tuning required\u003c\/li\u003e\n  \u003cli\u003eRemovable at any time to restore original behavior\u003c\/li\u003e\n  \u003cli\u003eWorks while engine is running; no startup sequence needed\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill installing this unit harm my engine or void my warranty?\u003c\/h3\u003e\n\n\u003cp\u003eThe Pooperws disabler is engineered as a safe, reversible add-on that does not alter factory hardware or software. Because it does not write to the ECU or change factory calibrations, it minimizes the risk of permanent modification often associated with tuners.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eNon-invasive plug-and-play design\u003c\/li\u003e\n  \u003cli\u003eNo ECU coding or permanent changes performed\u003c\/li\u003e\n  \u003cli\u003eUnplug to return to factory operation quickly\u003c\/li\u003e\n  \u003cli\u003eCustomer support available for installation questions\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat performance and drivability differences should I expect?\u003c\/h3\u003e\n\n\u003cp\u003eBy preventing cylinder deactivation, the module helps maintain consistent power delivery and smoother throttle response during acceleration and towing.

The Pooperws AFM DFM DOD Disabler is aimed at GM owners who want a quick, reversible way to prevent cylinder deactivation without modifying the ECU — especially those who tow, haul, or who experience throttle hesitation and engine vibration tied to AFM\/DFM events. It’s also suited to drivers seeking a simple, low-risk device to maintain full engine operation while preserving the ability to revert to factory settings. If you value plug-and-play convenience, a patented European-registered design, and responsive customer support, this module offers a practical solution for many GM V6\/V8 owners.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: How quickly does the disabler activate after plugging in?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Activation is immediate; once plugged into OBD-II the vehicle maintains full-cylinder operation right away.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I remove the device and return to factory settings?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes — unplugging the module returns the vehicle to its original AFM\/DFM behavior with no permanent changes.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Pooperws","offers":[{"title":"Default Title","offer_id":55171590422871,"sku":"B0GJP29C8D","price":86.43,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1050\/1524\/7191\/files\/pooperws-front-view-device.jpg?v=1790448471","url":"https:\/\/britishgarage.co.uk\/products\/pooperws-afm-dfm-dod-disabler-obd-ii-for-gm-4-3l-5-3l-v6-v8-plug-and-play-cylinder-deactivation-stopper","provider":"British Garage","version":"1.0","type":"link"}
