Buying Guide About AFM Disabler
From your above reading, you have the insights that the AFM disabler can let you have full-time control of your vehicle. So, you need to be very careful while you are committed to purchasing one to demobilize the AFM feature.
In our article on the best AFM disabler, we try to enlist certain points that you must consider before going to get one for your vehicle. Overlooking these points may bring devastation down on your engine.
One of the distinguishing features of a top-notch AFM disabler is the response time. The AFM disabler from a tip-top company like Range Technology ensures to disable the AFM system in a matter of seconds. So, if your purchased AFM disabler starts working immediately when plugged in, you can be sure of its functionality.
On the contrary, if the disabler fails to be in effect quickly, something is wrong. In that case, your car hesitates to decide whether to stick to the full-engine mode or turn off half of the engine’s valves. As a result, you may end up having a depleted engine. So, be careful while choosing the right one.
Whether the device is compatible with your vehicle or not, you cannot bypass it. You must check on your vehicle’s suitability with the disabler before heading to get one.
As the AFM technology is GM’s invention, most of the vehicles from General Motors come with the AFM-enabled program. If your car is not on the GM’s compatibility list, then you must take the pain to inspect whether the device fits in or not. The best way to check the compatibility is to use your vehicle’s year and model.
Compatibility with Tuners
Checking the disabler’s compatibility with the tuners is another crucial thing you need to look for. The reason is that a number of disablers don’t work with a tuner plugged into your vehicle. So, go for the tool that can be connected to the OBD-2 port alongside the tuners.
The car you purchase comes with a factory warranty card. If you make any changes yourself, then the warranty gets null and void. Some disablers reprogram or modify the factory ECU system. As a result, your warranty gets invalid.
So, try to choose a disabler that reprograms or makes any modifications to the stock ECU. By doing so, the disabler doesn’t leave any traces, and you can get back to the AFM program again when needed without affecting the warranty.
It is wise to purchase the AFM disabler having a light on its body. The light will give you the signal if the disabler works properly. If your vehicle doesn’t match the disabler you’ve plugged in, then you will not get any signal.
