How To Disable Active Fuel Management AFM or DOD Easy and Free

How Do I Bypass Active Fuel Management?

Active Fuel Management (AFM) is a system used by General Motors to improve fuel economy. The system allows the engine to run on four cylinders when less power is needed, such as during highway cruising. This reduces fuel consumption and emissions.

Unfortunately, there is no way to bypass AFM. The only way to disable it is to install a special tune that disables the feature. However, this will likely void your warranty and may cause other issues.

We do not recommend doing this unless you are an experienced mechanic or tuner.

Can Gm Afm Be Turned Off?

The General Motors Active Fuel Management (AFM) system conserves fuel by temporarily shutting down half of the engine’s cylinders when they’re not needed. The benefit is a fuel economy improvement of up to 8 percent, which means you’ll save money at the pump. But what if you don’t want AFM?

Maybe you don’t care about saving fuel, or perhaps you’ve read that AFM can cause engine damage. Is it possible to turn off GM’s Active Fuel Management system? Yes, it is possible to disable GM’s Active Fuel Management system.

However, we do not recommend doing so unless you have a specific reason for wanting to do so. There are a few potential downsides to disabling AFM: 1) You’ll lose the fuel economy benefits: Obviously, if you disable AFM, you won’t be able to take advantage of the fuel savings it provides.

2) It could shorten engine life: Some experts believe that running an engine with fewer cylinders puts additional stress on certain engine components, which could lead to premature wear and tear. This is especially true if you frequently tow heavy loads or drive in hilly terrain, both of which put extra strain on an engine. 3) Your vehicle may not pass emissions tests: In some states, vehicles must undergo emissions testing before they can be registered.

If your vehicle doesn’t have AFM enabled, it may fail the test and require expensive repairs in order to pass. 4) You may void your warranty: Many automakers void the powertrain warranty if AFM is disabled on a vehicle covered by the warranty. So if something goes wrong with your engine after disabling AFM, don’t expect your automaker to foot the bill for repairs.

As you can see, there are several potential downsides to disabling GM’s Active Fuel Management system. Weigh these factors carefully before making a decision – in most cases, it’s best to leave AFM turned on.

Will Disabling Afm Save Lifters?

If you are in the process of shopping for a new car, you may have come across the term “AFM.” AFM stands for Active Fuel Management, and it is a fuel-saving technology found in many GM vehicles. When AFM is enabled, the engine will run on four cylinders when less power is needed, such as when cruising on the highway.

This saves fuel and reduces emissions. However, some car enthusiasts believe that disabling AFM will improve performance and help extend the life of the engine’s lifters. So, will disabling AFM save lifters?

The answer is maybe. Some people report that they have had success with this mod, while others have not. It really depends on your individual vehicle and how it responds to the change.

If you decide to disable AFM, be sure to keep an eye on your engine’s oil pressure and watch for any unusual noises or vibrations. As always, consult with a qualified mechanic before making any changes to your car.

What Cylinders Shut down on Afm?

Active Fuel Management (AFM) is a trademarked technology used by General Motors to improve fuel economy on their gasoline engines. The system can shut down half of the engine’s cylinders when full power is not needed, such as during highway cruising. The benefit of AFM is an improvement in fuel economy of up to 5% for V8 engines and up to 12% for V6 engines.

GM began using AFM in light-duty trucks and SUVs in the 2007 model year, and expanded its use to passenger cars in 2008. As of 2016, most GM vehicles with gasoline engines are available with AFM. Critics have argued that AFM can cause engine wear and decreased performance, but GM has defended the technology as being reliable and backed by extensive testing.

Problems After Afm Delete

If you have an AFM delete on your vehicle, you may experience some problems. The most common problem is that the check engine light will come on. This is because the computer is not receiving the proper signal from the AFM delete and thinks there is a problem.

Other problems can include poor fuel economy and decreased power. If you are experiencing these problems, it is best to take your vehicle to a mechanic or tuner who can help you adjust the settings on your computer.

Can You Disable Afm With a Scan Tool

If your vehicle is equipped with Active Fuel Management (AFM), you may be wondering if there’s a way to disable it. Unfortunately, there is no way to disable AFM with a scan tool. However, there are ways to work around this system to improve your fuel economy.

One way to do this is by disconnecting the negative battery terminal for 30 seconds. This will reset the ECU and disable AFM temporarily. However, once you reconnect the battery, AFM will be re-enabled.

Another way to get around AFM is by installing a performance tuner or programmer. These devices can often times allow you to disable AFM through their menus. However, not all tuners/programmers have this capability so make sure to check before purchasing one.

Lastly, some people have had success disabling AFM by disconnecting certain sensors related to the system. However, we do not recommend doing this as it can lead to other issues down the road and void your warranty. So there you have it, three ways to potentially disable AFM on your vehicle; however, none of them are guaranteed to work 100%.

If you’re looking for better fuel economy without having to worry about Afm restrictions then consider trading in your vehicle for one that doesn’t have this system equipped.

How to Disable Afm With a Tune

If you’re looking to disable your vehicle’s Active Fuel Management (AFM) system, there are a few different ways to go about it. One option is to use a special tune or programming device that will disable the AFM function without affecting any other systems in your vehicle. There are a few different companies that offer this type of service, and the prices can vary depending on the make and model of your vehicle.

In most cases, you’ll need to send in your vehicle’s computer module so that the company can create a custom tune for you. Once they have your module, they can usually turn around the tune fairly quickly – often within 24 hours. Once you receive the tune back from the company, simply install it in your vehicle and enjoy an AFM-free ride!

Chevy 8 Cylinder to 4 Cylinder Problems

If you own a Chevy with an 8-cylinder engine, you may be experiencing some problems. Many Chevy owners have complained about their engines suddenly becoming 4-cylinders. This is a serious problem that can cause your car to lose power and performance.

The cause of this problem is still unknown, but there are some theories. One theory is that the cylinder deactivation system might be malfunctioning. This system allows the engine to run on only four cylinders when less power is needed, such as during highway driving.

If the system is malfunctioning, it could cause the engine to become a 4-cylinder instead of an 8-cylinder. Another theory is that there might be a problem with the spark plugs or ignition coils. If one of these components is not working properly, it could cause the engine to misfire and become a 4-cylinder.

If you are experiencing this problem, it is important to take your car to a qualified mechanic as soon as possible.

5.3 Afm Recall

Today, we’re going to be discussing the 5.3 AFM recall that has been affecting a number of GM vehicles over the past few years. This recall is important because it can potentially lead to engine failure, and that can be a very serious problem. We’ll go over what the recall entails, how you can tell if your vehicle is affected, and what you should do if it is.

The 5.3 AFM recall affects certain GM vehicles that are equipped with the 5.3L V8 engine. These engines have a defect in the valves that can cause them to stick in the open position. This can lead to a loss of power and eventually engine failure.

The affected vehicles include the Chevrolet Silverado, Tahoe, Suburban, Avalanche, GMC Sierra, Yukon, and Cadillac Escalade from model years 2007-2014. If you own one of these affected vehicles, there are a few things you should look out for. One symptom of this problem is decreased fuel economy.

If you notice that your vehicle isn’t getting as good gas mileage as it used to, it could be an indication that something is wrong with the valves. Another symptom to watch for is engine misfires or hesitations during acceleration. If your vehicle starts having these kinds of problems, it’s important to take it to a mechanic right away so they can check for the valve issue.

If your vehicle does have the defective valves, there are a few different options for fixing them. The most common solution is to have the affected valves replaced with new ones. In some cases though, GM has issued extended warranties for these vehicles which will cover repairs if necessary.

Range Technology Afm Disabler Problems

If you own a diesel truck, chances are you’re familiar with the dreaded DPF (diesel particulate filter). This emissions control device is required on all new diesel trucks in order to meet EPA standards, but it can cause some serious problems. One of the most common issues is called “regeneration.”

This is when the DPF traps soot and other particles from the exhaust and then burns them off at high temperatures. Unfortunately, this process can damage your engine and even cause your truck to catch fire! Range Technology’s AFM Disabler is a device that prevents regeneration from happening.

It does this by interrupting the signal that tells the truck to enter regeneration mode. This means that your DPF will never need to be cleaned or replaced, and you won’t have to worry about damaging your engine. The AFM Disabler has been proven to work on many different types of trucks, including those with manual and automatic transmissions.

It’s easy to install, and it comes with full instructions. Best of all, it’s backed by a money-back guarantee, so you have nothing to lose except yourDPF headache!

Range Afm Disabler

If you have an older model Macbook Pro, you may be familiar with the “Range” AFM Disabler. This was a tool that Apple released to help fix an issue with the early models of their laptop where the screen would flicker when certain combinations of keys were pressed. While this problem has since been resolved, the Range AFM Disabler can still be useful for those who are experiencing other issues with their Macbook Pro’s display.

The Range AFM Disabler is a simple utility that allows you to disable the Automatic Frequency Modulation (AFM) feature on your Macbook Pro. This can be helpful if you are having problems with your display, such as flickering or distorted colors. It is important to note that this utility should only be used if you are experiencing these kinds of problems; it is not meant to be a general-purpose display adjustment tool.

To use the Range AFM Disabler, simply download and install it on your Macbook Pro. Once it is installed, open the utility and follow the instructions to disable AFM. After doing so, restart your computer and see if the problem persists.

If it does, you may want to try another approach or consult with an Apple support specialist.

Afm Disabler Autozone

If your car is giving you trouble, you may be tempted to take it to an auto mechanic. However, before you do, you should check to see if your problem is something that can be easily fixed yourself. One such problem is a disabled AFM (Air Flow Meter).

The AFM measures the amount of air flow into the engine. It then uses this information to calculate the correct fuel mixture for the engine. If the AFM becomes disabled, it will no longer be able to accurately measure air flow.

This can cause the engine to run too lean or too rich. Fortunately, there is an easy fix for a disabled AFM. All you need is a simple device called an Afm Disabler.

This device plugs into theAFM and fools it into thinking that there is no airflow at all. This effectively disables theAFM and allows the engine to run without it. Installing an Afm Disabler is a relatively easy process that most people can do themselves in about 30 minutes.

Once installed, your car will run just like it did before the AFM became disabled. In fact, many people find that their cars actually run better with the Afm Disabler installed!


There are a few ways that you can disable AFM without a tune. One way is to disconnect the vacuum line that goes to the AFM solenoid. This will prevent the engine from going into AFM mode, but it will also cause your check engine light to come on.

Another way is to install an aftermarket air intake system. This will allow more air to enter the engine and prevent it from going into AFM mode. Finally, you can install a tuner that will disable AFM altogether.
