  • Locks your ride in V-8 (or V-6) mode for immediate power!
  • Reduces throttle lag and provides more consistent power delivery across the entire power band
  • Disables Active Fuel Management to unleash the true power of your engine
  • Eliminates annoying cabin drone when used with aftermarket exhaust systems
  • The Range AFM Disable Device has been shown to reduce oil consumption many vehicles with Active Fuel Management exhibit from switching between 4/8 cylinder modes
  • Installs in seconds with no tools, simply plug it into your OBD-II port
  • Does not reprogram the ECU, so no watermarks are left for the dealer to detect
  • Made in the USA
  • Your Range Active Fuel Management Disable Device boasts a 1-Year Warranty
Description:

When it comes to horsepower, dropping cylinders is a recipe for flat-lined performance. This especially holds true with Active Fuel Management (AFM) systems installed on V8-powered rides and rigs. While they're great for saving you at the pump, turning a V8 monster into a wheezing 4-banger understandably kills performance. Wake up all 8 of those potent pistons for full-time power with the Range Technologies Active Fuel Management Disable Device.

If Active Fuel Management has a stranglehold on your ride, the Range Technologies Active Fuel Management Disable Device is the answer. This powerful module completely disables AFM, allowing your ride to run on 8 cylinders constantly. All it takes is a few seconds to locate the diagnostic port in your ride and plug in the Range Technologies Active Fuel Management Disable Device. This results in a more responsive ride with all 8-cylinders available full-time and ready for action.

No adjustments are needed to enjoy the full performance of the Range Technologies Active Fuel Management Disable Device. And all changes are fully reversible, so if you need to restore the stock Active Fuel Management program, simply turn off the engine and unplug the device. Say goodbye to unpredictable power and snail-like acceleration with a Range Technologies Active Fuel Management Disable Device. Best of all, Range backs their Disable Device with a 1-year warranty.

Notes:
  • The Range Active Fuel Management Disable Device cannot be used in conjunction with aftermarket tuners that need to remain attached to the diagnostic port.
  • The Range AFM Disable Device is NOT a programmer and does NOT change the ECU's mapping or memory locations. It is a dynamic interactive device that actually participates on the vehicle's communication line (bus) and revises the way the ECU uses its STOCK calibration to lock it in V8 mode. Since the Range AFM Disable Device does not change the factory programming in any way, your vehicle will still comply with the factory certified emissions profile.

2014 GMC Sierra 1500 Crew Cab 4X4 5.3L Range RA003G

This device is great. Used it for one week now and it appears I have better accelerator response and according to my driver display I'm getting better gas mileage but time will tell. My on opinion it's a bit pricey.

Get the monkey off your back

No more manual shift required to get power from the hamstrung manufacturer design. If GM were smart I'd have a simple button determining if/when I wanted their stupid chaotic cylinder control.

The little thing works GREAT!

I had read the reviews before I purchased the Active Fuel Management Disable Device and decided to go ahead and get it for our 2007 Chevy Tahoe. It could not have been easier to install... literally just plugs right into the OBD II port. That's it! And it instantly started working. The Tahoe did not go into 4-cylinder mode anymore. I was worried that at night it would drain the battery, but it didn't. Even after the Tahoe sat for 5 days, it started right up. Excellent product!

So far so good!

I had read a lot articles and reviews on this product. I was just looking for something to stop the switching back and forth. I have noticed that the delay when pushing the gas is pretty much gone, the power is always there, and the mpg didn't really get affected. I think the firmware may have been bad it a lot of the other peoples that said they were having issues. The only thing I have noticed is my remote start has a temper now.

range

I have had problems with idle and also engine going from 8 to 4 cylinders on the highway. After installing the range on my 2011 silverado, i have to say idle has smoothed out and no more studdering on the highway. I highly recommend this device.

Beats a programmer

I was going to buy a programmer and CAI but instead I bought the range. It unlocked all them 4 horses only getting used here and there and put all 8 horses in full stride at all times. It's compact, sleek and does what it's supposed to. I'm very pleased

Popped in and works great!

I installed it two weeks ago and haven't had a minutes trouble. It works great and haven't noticed a change in fuel mileage. My acceleration is way more responsive and I think it improved the way it runs overall. I wouldn't drive without it ever again.
