DIY - How to Disable or Delete AFM/DFM! (Chevy or GM Vehicles)

[@TDub_ADV]

Just an FYI, software deleting the AFM/DFM does NOT solve the lifter issues. They still can and do fail with AFM/DFM disabled by software. I am one of many people that have experienced lifter failure with it software disabled. The ONLY way to get rid of it is a full delete kit with a new cam, lifters, and a vlom block off plate in addition to software. ,

[@8020Media]

They still can fail because you of course still have all of the AFM-equipped hardware in the car, like the special AFM lifters that are inherently problematic. But disabling it via software does still significantly reduce the likelihood of it happening, just doesn't completely prevent problems. But yes, only way to get complete protection is to do a full delete but I would recommend doing that only if you actually have a failed lifter first, otherwise the cost is tougher to justify.

So I have been curious about these. I just got my 2022.5 Silverado 1500 with a 2.7 back from the dealer this past week after having it being gone for 2 weeks. I had a camshaft and lifter failure at 50,000 miles. My question, and concern, is if you are not having the active fuel management cycling while it's disabled, does that lead to other problems with the system down the road because it's not being activated or lubricated... specifically meaning the camshaft and the mechanism that causes it to cycle back and forth when activating and deactivating cylinders

@@8020Media Don't buy a Silverado. Shouldn't have to tear the engine apart at 26K. BTW I did "take great care of it" and it still imploded. Dealership fixed it but they put the same garbage parts back in it so now 5000 miles later guess what, making noise again. I understand you are trying to sell a product but these engines are garbage until you delete the system all together

If there's any lawyers out there watching videos relating to the poor design of the GMC engines and transmission there needs to be a class action law suit against GMC for knowingly setting up consumers to fail. I had to replace both my engine and transmission after 112,000 miles which is just over the warranty mileage and a few months after my extended warranty expired. The DOD/DFM/AFM and the transmission temperature sensor have been known failure issues since their inception. I've been a loyal American made car owner for over 47 years and will never own another one. Toyota Tundra here I come. All these ridiculous environmental constraints and regulations are just added costs to the consumer with no documented benefit to the environment. Total crap!

I am currently in the midst of this exact thing. My mechanic (Chevy will not work on my 2010 Silverado 1500) has torn my engine apart and cannot find the problem. This costs me tons of money without fixing my problem. How can I join the class action suit to recover the $4,500 I’m out so far. I’ll add another $2,000 to cover labor for reassembly of the engine and tuning the vehicle.

Best way to avoid problems is dont use the engine oil life indicator go by miles be mindful of super long idle times daily that breaks down oil just like miles 0-15w oil is really thin and any sludge buildup from poor maintenance will cause problems with DFM
