Shopping Guide On Best Active Fuel Management(AFM)

AFM disables activating every of your engine’s cylinders, removing drones, and providing your car with more power.
The effects of this? Your engine consumes less fuel and oil. Before you buy one, here is what you must consider:
Performance
The AFM disabler you choose must be able to meet up with the features it advertises or boasts about.
Unconventionally, many manufacturers include features their products don’t have, luring you into buying a substandard disabler.
A good piece of advice is to stick with a known and reliable brand. Refer back to our top 10 best AFM disablers, and pick a product that resonates with your engine’s needs.
Price
A very important factor to consider before buying an AFM disabler is price. They often feature various design materials, hence, varying prices.
Some AFM disablers are quite pricey, yet with excellent solutions, why some are affordable with mid-performance.
Others are complete rip-offs, which is one end you should be wary of.
You also need to be aware that while some offer amazingly reasonable prices, they are not great products and may not offer what you’re looking for.

Read More Questions About AFM Device
01. What is an AFM disabler?
AFM disablers are small gadgets that plug into the diagnostic port of your vehicle.
They often have software that reprograms a user’s engine, allowing them to utilize the full cylinders at all times.
A good way to think of AFM is as a bypasser rather than as a disabler, as it, in operation, bypasses the active fuel management system.
The effect is that your engine wouldn’t drop cylinders abruptly and occasionally too. These are the benefits of not just using an AFM disabler but the best chevy afm disabler.
Your engine gets back its full power.
The major thing a disabler tries to do is to get a user’s engine back to optimal performance. How would it do this?
It simply will improve the power gains of the engine. Hence, the dripping of cylinders is taken care of.
Having more power means the pressure on a user’s car wheels is now lowered. More power also means more control. The risk of losing balance is hence minimized.
Reprogramming can be reversed.
A good AFM disabler does not necessarily impact the powertrain or system of a user’s vehicle. If you want your vehicle back to the factory function, all you have to do is take out the disabler.
The great thing about this is that it leaves no trace of being there before, as your engine returns to an unnoticeable default mode once again.
Assist vehicle engine
Once installed, the pressure put on your car to limit cylinder use is ousted. The implication of this is that your car can now run smoothly without having to work extra hard.
This disabler, in the long run, is cost-efficient, as you wouldn’t have to keep spending on maintaining the engine.
02. How do AFM disablers differ from AFM delete kits?
AFM disablers are necessary when an AFM lifter isn’t failing yet. Disablers often serve as preventive maintenance tools.
In cases where the AFM disabler is failing, an AFM delete kit is your best shot.
You should be aware, however, that in a case where a delete kit is installed already, but you don’t have access to a Programmer, a disabler is still a great choice.
To do this, the AFM solenoid pack needs to be left connected. This is to make sure that codes are thrown.
How AFM works
When the vehicle engine is low, it does the following:
- Computer sends a signal of the situation to the LOMA
- This opens the LOMA solenoid
- Oil via the OFM towers then flows to the special lifters
- The oil then collapses the plunger
- The collapsed filters do not impact the pushrods, hence leaving the valves closed. Since air is trapped, the four cylinders do not provide power.
03. How does AFM affect performance?
Excessive oil consumption
If your engine is running on AFM mode, you’re bound to witness your engine always needing more oil. This may be the most serious way an AFM affects an engine’s performance.
This is because the setup uses an oil pressure relief valve. This relief valve sprays oil directly on the piston skirts.
This oil spray, in most cases, seems to overwhelm the piston rings, hence gathering at the combustion chamber’s surface. This causes carbon build-up.
Transmission shudder
AFM causes engine transmission to shudder to a vehicle it’s installed on. This means your vehicle’s transmission begins to shake, or there’s a noticeable tremble.
This is majorly caused by AFM initiating contamination of transmission fluid.
Unresponsiveness of engine
There’s a considerable difference between the sensitivity and responsiveness of an engine that has an AFM mode activated on it and one without.
There’s always a delay in the acceleration of the engine, and this could be really frustrating when you need to speed a little bit higher.
04. Will disabling AFM save lifters?
Disabling AFM, even with the best AFM tuner, does not help filters in any way. Adding AFM delete kits does not save as much money as compared to changing the AFM valve filters altogether with new ones.
Your AFM lifters failed due to oil pressure or control.
AFMs activation or deactivation is determined by the extended valve lifter oil manifold.
Its function is to exert control on how the engine oil flows into the intake of the active fuel management system, as well as the exhaust valve lifters. AFM failure occurs first for the following reasons:
Low oil
When there’s only little oil available in the engine, the lifters are bound to get damaged.
In worse scenarios, they fail completely. The sliding surfaces of the lifters require enough oil to perform.
Poor quality oil
To function smoothly, AFM lifters need a good quality oil. A poor quality one only results in its underperformance or failure altogether.
This ultimately costs you a replacement of the lifters.
Wear and tear
In some cases, there aren’t any noticeable problems with your lifters, yet they fail. Constant use results in degradation of performance.
It is advisable to have your engine lifters replaced once you notice they’re beginning to get old and malfunctioning.
05. How do I disable AFM?
If you have looked into your engine’s performance and feel there is a need to turn off active fuel management, there are two ways to do that.
One of them is to install an AFM delete kit; the other is to install an AFM disabler.
Install an AFM delete kit
This is only recommended when the lifter fails or when you’re performing upgrades.
The AFM components are replaced with standard parts from the AFM delete kit. Here is what you should know:
- First, upgrade to a non-AFM camshaft. The reason is that the cam lobes located in the four cylinders are different.
- Shut down the AFM system using a computer programmer
- It is recommended to plug the pressure relief valve into the oil pan
Conclusion
In the end, having an AFM disabler installed on your car’s engine is a necessity if you want to drive your vehicle in full-cylinder mode.
