I had a local tuner shut it off. I also think the hypertech programmer does it

AFM Disabler, it plugs in to the OBD port. Or custom tune OR Use M5 every time, its deactivated in M5

Or M7 on the 8 speed

Man m7 you would think could drive around 65 without needing to go to 8th and enjoy a nice ride.

Welcome to this forum! You will find a lot of information and discussion regarding this topic on this site. I personally like this feature and it has never created a concern for me or changed the quality of my ride. The only way it is noticeable is the green indicator on the dash. If you are noticing a difference perhaps it needs servicing rather than removal.

Yeah i like mine too. It saves me some fuel and since i dont have the need to smash the gas pedal all the time, it works for me.

I have read that people disable the V4 mode, but why? What are the supposed advantages of doing this?

For me I just found it annoying and after disabling it my mileage didn't change. It was always going in/out of V4 mode and I never thought the transition was as smooth as GM advertises. I used a DiabloSport inTune i2 tuner which cost me $360.

The AFM has been seamless on this 2017, as was my 2013. I disabled the AFM on the 2013 via the Diablosport Intune I-1000 mainly due to the Vortecs having oil consumption issues later in life due to the cylinder deactivation. I have not heard of this on the Ecotec3 line of engines, but I am sure some have experienced it, probably due to poor oil change habits.

I think v4 mode is pointless. When u had it my truck qpuod constantly fluctuate between 25-30mpg. With it off. I can stay at a constant 26 27 mpg so it's all in how you look at at

Mostly to avoid the drone associated with V4 mode when running an aftermarket exhaust. I have a Borla muffler and the sound when it switches into v4 can be annoying at times, but the 6.2 sounds oh so sweet when all 8 pistons are pumping. I also despise the lag I feel when I hit the gas if the truck is in V4. Seems like it takes about a second to get full power all the way down the driveline once the other 4 cylinders kick in. I’d rather have all 8 cylinders poised and ready instead of napping. Just my preference.

Personally for me I like the V4 at speeds 60 and under. When you start doing 70+, it's annoying as hell constantly kicking in and out. You don't notice it so much in the way the engine runs, but the torque converter is constantly searching like it doesn't know where it should lock-up. By the time in locks-up, it's unlocking and moving again. That'd be about my only real complaint. I loved my Range AFM disabler, however I can't run it right now as I'm doing testing to see if it was the cause of my reduced power steering assist error messages.

      My brother has an Escalade. The warranty has expired so he told his wife to go to the Valvoline quick lube he uses some times. They told her if her car was a 2020 and newer 6.2 engine they wouldn’t touch it. Hers is a 2019, so they did the oil change.

      2026 6.6 L5P oil cooler leaking oil at 4,000 miles

      The oil filter has NOTHING To do with oil leak. GM sources parts from 1,000's of vendors and as with anything mass produced, flaws are unavoidable.    Putting a larger oil filter will do nothing but satisfy emotions. The OEM filter is designed for the engine and perfectly capable of handling the demands on the engine. Oversize oil filter could result in reduced flow and overall lower oil pressure.

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.
