TOPDON AFMD AFM Disabler for GM Vehicles
Designed for GM vehicles equipped with AFM, the TOPDON AFM Disabler keeps your engine in full-cylinder mode. Eliminate shudder and restore smooth performance with a simple, plug-and-play solution. No ECU modifications, no battery drain-just reliable power you can set and forget on supported GM vehicles, including Chevy Silverado and Tahoe, GMC Sierra and Yukon, Cadillac Escalade, and more. See the compatibility list for supported model years.
Features:
-
Consistent Power. Smoother Driving
By preventing your engine from switching into cylinder-deactivation mode, the AFM Disabler helps reduce shudder, uneven response, and the disruptions that come with AFM operation. The result is a smoother, more consistent feel behind the wheel. -
Plug and Play, Ready in Seconds
No tools or configuration required. Plug the AFM Disabler into your vehicles OBD-II port and AFM is disabled automatically each time the engine starts, helping maintain consistent engine operation from the moment you begin driving. -
Help Reduce the Risk of Costly AFM Repairs
AFM systems repeatedly switch cylinders on and off during normal driving, which can cause engine issues in some GM vehicles. The AFM Disabler helps reduce the risk associated with AFM operation and supports more consistent long-term performance. -
Unlock Full V8/V6 Engine Performance
Designed for GM vehicles equipped with AFM, the AFM Disabler prevents cylinder deactivation across supported GM models. It delivers consistent engine operation without requiring tuning, configuration, or permanent modification. -
Automatic Sleep Mode, Minimal Battery Draw
With intelligent auto sleep and wake, the AFM Disabler is safe to leave plugged in. It powers down when your car is parked and instantly wakes when you drive, using almost no battery. Enjoy full engine performance without worrying about your battery. -
No Reprogramming, No Permanent Modifications
The AFM Disabler works without reflashing or altering your vehicles ECU. Simply unplug the device at any time to instantly return your engine to its original cylinder-deactivation setting. No AFM elimination, no impact on emission inspections.
