Now this info answers a lot of questions about gen 4 and 5 reliability and AFM DOD. I have the RANGE Dis-abler on my 2015 5.3 Silverado. I leave it plugged all the time. I'll take the hit on MPG, I didn't like the shudder I got when cruising at 30-45 mpg, converter locked up, in over drive, on 4cyl mode. The switching in and out of these systems, made me say, Oh Hell No. Disabled in v8 mode is smooth as expected. This system shifts thru all six speeds pretty quickly even in steady cruise, and the shutter wasn't going to cut it. Pulling a trailer with car, at 60 mph+ with AFM ENABLED, is no problem, and I get 20 mpg+. But I just leave it disabled.

With regard to the high pressure oil pump spraying too much oil on cylinder walls, is the plug fix for this issue advised when just going the deactivation route?

Awesome job explaining this!!! You should be in charge at GM because they don’t seem to know how this works themselves. ( failure of lifters on my 2021 Sierra with only 8.800 miles and they replace with same parts so just a matter of time I guess). Anyways thanks again for the great explanation.

Nice simple explanation and tempered to "soften" just how much trouble the system can create - simply put, several issues can trash an engine. Unfortunately the system and its unique parts are more complicated than needed to be explained and require diligent attention to maintenance to reduce the possibility of a failure. Anyone researching just exactly how the entire system functions will find out just how mechanically "busy" the extra functions required are, and see all the areas for potential failure. So far, mine ('07 5.3 Silverado) has functioned well, but is annoying. On flat level roads there's no sign when it is engaged except that because I have modified exhaust - the truck Sounds like it's missing. The annoying part is when the road is at all hilly and it's below expressway speeds. The system "hunts" turning on and off frequently, and the truck feels lazy going up a longer hill until the system Stays off. Best to disable it and avoid possibly destroying an engine.

This video is extremely long winded though for such a simple answer, if you don’t want to do major engine work, just buy an HPtuners mpvi2, you can even download the VCM suite for free and it comes with a few sample tunes to look through the program. Disabling the DOD on most Silverado’s is literally just a drop down option that says enable or disable, once the vehicle is flashed you can remove the mpvi2 and it will NEVER run in v4 until you flash it back. You can even keep the warranty on the vehicle if you just change it back before you get to the shop lol pretty much impossible to tell if it has been flashed or not.

I'm one of many who had the expensive experience of an AFM lifter failure on a low mileage engine. ( just out of warranty) The internal damage was extensive, and expensive. I didn't know about the delete kit until the rebuild was nearly complete……however I did buy an AFM disabler for my 6.2. My fuel mileage is exactly the same as before in mixed, city, and highway driving!

If I delete and keep the original valley cover (for check engine light), does anything need covered or plugged up so oil doesn’t flow through the afm system downstream from the solenoid?

As soon as I started getting lifter "tic" I installed a disabler. Within a few months the lifter noise became quieter and intermittent until it totally disappeared and has never came back after over 65k miles. I got lucky lol. But oddly I gained .6 mpg instead of losing mileage lol. Hardly noticable. But downshifts were definitely improved. But the 6L80E is still probably my least favorite transmission ever lol

Will this method apply to the GM 2.7 L 4 cylinder engine in the Sivlerrado's I wonder?

Found a gently used and well maintained '13 silverado with AFM. Taking a chance on it in this market. That Range disabler seems to be the way to go for now at only 60k miles. Do y'all think I need to put a different oil pump in and block the PRV?

Great video and very informative. This explains why some people still have lifter failure even after they've installed a disabler because it seems that the lifter or other components pertinent to the AFM/DFM system were already failing at that point. So in short, it might seem that the best solution is to purchase the disabler and install it almost immediately after you purchase the vehicle. This way, you are actually taking preventative action and not just putting a band-aid on an already bad part.

Or I could spend $200+ for a Range AFM Disabler. If I follow the owners manual instructions for manually setting the transmission to "5" will it have any negative effect on my transmission if I drive at highway speeds of 70 mph or more? Or is the Range Disabler the better option?

You pay someone alot of money to drill all the old bolts out and hope they don't screw up you have to buy a new cylinder head or dorma. Makes a bracket you can scre to the back of the head and uses a bolt to push the manifold back in place for like 10 or 15 bucks. I used it 3 years ago and I've have zero problems with it and no More tick tick tick at cold start. Again super super common problem, always assume the easy stuff 1st don't always assume the worst.

I got 160k hard miles on my 08 without issue. Make sure you run the proper oil in the engine or they will burn oil like crazy. Ask me how I know. That being said, when the engine inevitably takes a dump, I’ll yank it out and do a cheap rebuild and kill all the AFM components. This pickup is always towing or pushing a plow, that 4 cylinder nonsense isn’t saving me any fuel. They’re good engines though. We have several in the family. Intake gaskets and oil pressure sensors are the main repairs on them. No big deal. Do them both at the same time and don’t worry about it for years to come. Always used FelPro gaskets with great luck.

Is it possible to reflash to ecm to permanently disable AFM? It would be nice to not have the module plugged into the OBD port at all times and have to depend on it.

What would happen if you just unplugged the electrical connector to the solenoids on the valley cover? I'm guessing it would throw a code, but it wouldn't allow the motor go into AMF or DFM either.

actually i did the delete and my previous valley cover and solenoids are sitting on top plugged in. If i unplug it, it runs in V4 full time. trying to decide if I just want to buy the chip or pay the same price for someone to program, or just buy a programmer..charge $150 lol

If no air can get in or out with afm engaged, but the piston is still moving up and down, how does the cylinder fill with air and expel air everytime the piston goes up and down?

The system has the ability to precisely time the valves to close at given points in crank rotation. It times the valves to close on squeeze (compression) for 2 cylinders, and suck (intake) on 2 cylinders that are directly opposite in the firing order. And the 4 that are squeezing and sucking against each other have their fuel injectors turned off. With 2 on squeeze and 2 on suck, they act like springs against each other. They are not pumping any air, that would defeat any advantage by causing the deactivated cylinders to do work.

With AFM engaged, the air doesn't go in or out. The cylinder acts as an air spring.

Why is cylinder deactivation bad for the oil?

@MonzaRacer

2 жыл бұрын

It's not bad for the oil it's the fact that on certain models they don't have the oil deflector for the bypass valve and it splashes oil up on the cylinders or early models that actually squirt extra oil up on the cylinders which creates excessive oil consumption.

Using the AFM disable device will only work if lifter damage has not yet begun. The other, and most important part is changing oil every 4000-4500 miles. These engines do not tolerate wear well if going to a longer oil change interval. Having done these two things will lessen the chances of lifter failure considerably.

SERVICE 1956: I'm not a mechanic and, so, my question. Does your suggestion to change the oil every 4000-4500 miles still apply if I'm using Mobil 1 synthetic oil? As a note also, I have no engine oil loss after 6,000 miles (so far).

@service1956

2 жыл бұрын

@@lazurm There are 2 problems that these engines have. First is that they do not tolerate dirty oil for an extended period of time. The oil itself will not break down a whole lot in 5000 miles but, the problem remains when hydrocarbons form inside the crankcase contaminating the oil. Also, short trips during cold weather will result in moisture to form inside the crankcase. This is bad, especially for these engines. Tuning out the AFM will keep it in full time 8 cyl mode. Therefore the VLOM solenoids will not activate, and the lifters will not activate. Doing these 2 things will greatly lessen the chance of having AFM related problems. Another problem I just thought about is that there is a filter screen under the oil pressure sending unit that gets clogged and can cause a problem. This is also brought on by going too long between oil changes.

You can if you change the camshaft. The AFM camshaft is different in order to have room for the AFM lifter springs on the cylinders it deactivates.

Read your owners manual. There is no reason to install AFM delete. As instructed in the Owners Manual shift into M. Whatever gear you are in it will be displayed. Then tap up to the gear you want I usually go to 5 or 4. The xmsn is not strained because it is electronically controlled. Now as stated in the Owners Manual when 5 or lower is selected your engine CANNOT go into V4 mode i.e. the AFM is not available! Another plus is when going 70 on flat highway still have AFM available for 20 mpg. No need for AFM delete bandaids.
