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.

Best $200 I have spent

This does exactly what it says and I want to thank everyone who took the time to write a review. My truck drives so much better, no hesitation with the valves or the transmission and as for the gas mileage I don't see a difference. My truck runs and drive so much better

Solved my shutter problem

I was experiencing a shutter on braking to a stop as the AFI switched back to V8 mode. After the simple plug and play tool was installed the vvehicle is smooth as silk. The difference on fuel economy us hardly worth mentioning. Fast shipping and great results. Thank you.

Great investment

I have a 2018 Chevy Colorado and a friend of mine who ended up spending a lot of money due to his lifters went out and had to be replaced it was recommended to him. I want to keep my truck at its upmost performance and after reading and research I am glad I opted to purchase this product. It has only been in my truck for less than a month and I have noticed a different in the way it runs by remaining in 6 cylinders.

Range Tech, Easy and Fast Fix

Literally, just plug this in and your constantly in 8 cylinder mode all the time. No worries about lifters gettting stuck and creating problems in the future. Yes you loose about 1 mpg. Excellent product

works great

Does exactly what its supposed to do on my '18 Silverado, keeps it running on all 8 cylindersat all times. To be honest, with this lockdown going on I've only driven around town so I don't know if it will effect my mileage and even if it does I don't care. I also recently put a pedal commander in and everythings humming along pretty good so far.
