Customer Questions & Answers
-
Question:
What is the purpose of the AFM-DFM Disabler?
Answer: The AFM-DFM Disabler is designed to disable the Active Fuel Management (AFM) system in GM motors, enhancing engine performance by preventing the engine from switching to a fuel-saving mode. This device helps maintain the full V8 operation consistently, offering improved throttle response, better power delivery, and a more engaging driving experience. Users often find that it eliminates the common complaints associated with the AFM system, such as hesitation or rough idling. -
Question:
Is the AFM-DFM Disabler compatible with all GM vehicles?
Answer: While the AFM-DFM Disabler is specifically designed for V6 and V8 engines compatible with GM motors, it's essential to verify compatibility with your particular vehicle model. It can effectively eliminate AFM operation in many popular GM vehicles, including Chevy Silverado, GMC Sierra, and others equipped with GM's AFM technology. Consult your vehicle's specifications or user manual to confirm that the disabler will work seamlessly with your engine. -
Question:
Will using the AFM-DFM Disabler affect fuel economy?
Answer: Using the AFM-DFM Disabler will likely reduce the fuel economy benefits associated with the AFM system, as it keeps the engine running at full capacity without switching to a lower fuel mode. However, many users prioritize performance and power over slight increases in fuel efficiency. It's common for drivers using this disabler to enjoy a more responsive engine, and in some cases, they find their driving experience more enjoyable despite marginal increases in fuel consumption. -
Question:
How do I install the AFM-DFM Disabler?
Answer: Installing the AFM-DFM Disabler is relatively straightforward and can typically be done in a garage or home without professional assistance. The device plugs into your vehicle's diagnostic port, requiring no specialized tools or modifications to the engine. Clear instructions are provided in the packaging, guiding you through the process. Many users report successful installations in under 30 minutes, allowing them to quickly enhance their vehicle's performance. -
Question:
Can the AFM-DFM Disabler be removed easily?
Answer: Yes, the AFM-DFM Disabler can be removed easily if necessary. Since it connects directly to the vehicle's diagnostic port, you can simply unplug it without causing any permanent alterations to your vehicle's engine system. This feature is particularly useful for those who may want to revert to the original settings or sell their vehicle later. Keep the disabler in a safe location so that you can reinstall it whenever needed. -
Question:
What improvements can I expect after installing the disabler?
Answer: After installing the AFM-DFM Disabler, users can expect noticeable improvements in throttle response, overall power, and smoother engine performance. The device keeps the engine running in full power mode, eliminating the potential for rough transitions between V4 and V8 modes. Many users report improved acceleration and a more consistent driving experience, especially during towing or carrying heavy loads, where power is critical. -
Question:
Is the AFM-DFM Disabler safe to use?
Answer: Absolutely, the AFM-DFM Disabler is designed with safety in mind and does not harm your vehicle's engine or affect its reliability. The device simply overrides the AFM functionality, allowing the engine to avoid unnecessary fuel-saving modes that can cause performance issues. Users appreciate that it enhances driving comfort and power without compromising engine safety, with many reporting no adverse effects on engine health. -
Question:
Who would benefit most from using an AFM-DFM Disabler?
Answer: Drivers who frequently tow, haul, or engage in performance driving are the most likely to benefit from using the AFM-DFM Disabler. Those who own GM trucks or SUVs that experience performance hiccups due to the AFM system will find significant advantages. Additionally, performance enthusiasts seeking to enhance their vehicle's responsiveness and drivability will appreciate the consistent power delivery that the disabler provides. -
Question:
Does the AFM-DFM Disabler void my vehicle's warranty?
Answer: Using the AFM-DFM Disabler can potentially impact your warranty due to modifying how the vehicle operates. However, it does not change the hardware or permanently modify the engine, keeping the integrity of the vehicle intact. In most cases, dealership policies vary, so it's advisable to check with your dealership before installation. Users have found it beneficial to keep the original factory settings to revert back if needed. -

OBDCAR Code Readers & Scan Tools OBDCAR-L-O Editorial Review
**** The OBD2 plug module has garnered positive feedback from customers who have installed the device in their vehicles, particularly in older GMC models such as the 2008 pickup and 2017 Tahoe. Users praise its ease of installation and simplicity, highlighting that it requires no complicated operations after plugging it into the OBD2 port. A key benefit noted by customers is the immediate performance improvement – many reported an increase in power and better fuel efficiency after the module disabled the Active Fuel Management (AFM) system, allowing their engines to run in V8 mode Consistently. Customers express relief that the module prevents the engine from entering V4 mode, which is a significant concern for those with high-mileage vehicles, as it helps avoid issues related to collapsed lifters and oil clogs. Several users emphasized the importance of regular oil changes alongside using the device, noting that extended oil change intervals could lead to further complications with AFM systems, such as damage to cams and lifters. Moreover, the module does not create persistent changes within the vehicle’s system, allowing users to simply unplug it when necessary, such as during a State Inspection. This feature enhances user control and adds to the overall positive reception of the product. A common sentiment across the reviews is strong satisfaction, with many customers recommending it as a worthwhile investment to prolong engine life and performance. **
