If you’re considering deleting the Active Fuel Management (AFM) system from your General Motors vehicle, you’re not alone. Many GM owners want to optimize their engine performance and prevent issues tied to AFM operation. In this tutorial, we’ll walk through the process of selecting and using a gm afm delete kit to help you achieve a better driving experience.
Why Delete AFM?
The Active Fuel Management system is designed to improve fuel efficiency by shutting down half of the engine’s cylinders under light load conditions. While this can enhance fuel economy, it can also lead to several issues such as:
Engine performance fluctuations
Increased engine wear
Potential for lifter failure
By deleting AFM, you’re likely to see improved performance and more consistent power delivery.
What You’ll Need
AFM Delete Kit: Choose a reliable AFM delete kit designed specifically for your GM model. Most kits come with necessary components like new lifters, gaskets, and a tune.
Tools: Basic hand tools such as wrenches, sockets, and screwdrivers. You may also need a torque wrench for proper installation.
Tuning Software: AFM removal typically requires engine tuning to prevent check engine lights and optimize performance. Consider options like HP Tuners or EFI Live.
Step-by-Step Guide
Preparation: Park your vehicle on a flat surface and disconnect the battery to ensure safety.
Remove Engine Covers: Take off any engine covers to access the intake manifold and cylinder heads.
Disassemble: Depending on your kit, you might need to remove the intake manifold, valve covers, and associated components. Keep track of bolts and parts for reassembly.
Install AFM Delete Components: Follow the instructions provided with your kit. Typically, this involves replacing AFM lifters with standard lifters and resealing with new gaskets.
Tune the ECU: Using your chosen tuning software, upload the recommended tune to your ECU. This will disable the AFM and ensure your engine runs smoothly.
Reassemble and Test: Reinstall all components, reconnect the battery, and start your engine. Monitor for any warning lights and listen for unusual sounds during the test drive.
Final Thoughts
Removing AFM can significantly enhance your engine’s performance and reliability. Be sure to do your research on the kits available for your specific GM model, and don’t hesitate to seek help from fellow forum members if you’re unsure about the installation process. Happy wrenching!
Feel free to ask any questions or share your own experiences with deleting AFM below!
The GM Active Fuel Management (AFM) is designed to optimize fuel efficiency by shutting down half the engine’s cylinders during light-load driving. It’s great for saving gas, but many face issues with it over time.
AFM issues usually arise from the lifters malfunctioning, which can lead to noisy operation or a rough idle. Removing the AFM can be a game-changer for performance enthusiasts who prefer a smooth ride.
Great question! While AFM aids in fuel efficiency, many users report an overall better driving experience after removal, particularly in performance applications. Plus, the potential maintenance issues it causes can negate those savings.
Honestly, the AFM system has its place, but I think it’s overhyped. It might optimize fuel some, but the trade-off in reliability is not worth it for most of us. Just my two cents!
I support removing AFM, especially if you’re someone who drives their vehicle hard. I’ve had my share of problems with it from weird idle issues to loss of power. Not fun!
Yes! There are several guides online, including videos that walk you through the whole AFM delete kit installation. It’s easier than it sounds, just take your time.
Can you believe people still stick with AFM despite the issues? I’ve seen two friends get stranded because of it. Some just love it, I guess. But I can’t imagine the headache!
I think it’s crucial to reflect on why we keep certain systems. Do they really benefit us, or are they just there to meet regulatory standards? In this case, removing AFM seems to lean toward the latter.
