Description
Range Technology AFM/DFM Disabler
Keep all cylinders active — no tune required. This plug-and-play device disables AFM or DFM on your GM V6 or V8 engine, letting you drive in full-power mode all the time. No reprogramming, no permanent changes, and no warranty issues. Just clean power, every mile.
How It Works
Simply plug it into your OBD-II port. That’s it. The module instantly disables AFM/DFM and keeps your engine running on all cylinders — exactly how it should. Unplug it anytime to go back to stock.
Important:
- This device requires a functioning AFM or DFM system.
- If the solenoids are missing or deleted, the engine may default to 4-cylinder mode.
- If you’ve already removed AFM/DFM hardware, you’ll need a custom ECU tune instead — we can help with that too.
Why People Use It
- Eliminates cylinder drop and annoying shudder
- Helps with towing, throttle response, and general drivability
- Fully reversible and doesn’t touch your factory programming

- Works on most 2005–2020 GM V6 & V8 engines with AFM/DOD or DFM
- Compatible with cars, trucks, and SUVs from Chevrolet, GMC, Cadillac, Buick, and more
- Multiple color options available
