Chevy 2026 Trucks still have Dynamic Fuel Management ( DFM)

[Snagglefoot]

So how about it Bitogers. GM is still using DFM in spite of all the hand wringing at BITOG. Has something changed with the system?

Mods, I did screen shots from GM to show they are still using the system.

They're a very good looking truck. Too bad the engine is so unnecessarily complex.

Until the gas guzzler tax is killed it won't go away. Corvettes without afm have the tax and it's about 2k while ones with afm don't.

So how about it Bittogers. GM is still using DFM in spite of all the hand wringing at Bittog. Has something changed with the system?

New 5.7L debut in 2027 ?

Dynamic Fuel Management. Sounds harmless. A lot better than Multi-Cylinder Deactivation.

If it's the 6.2 it should be labeled as DISASTER Fuel Management! Gets infinity MPG on the back of a rollback with a blown motor!

The third rebranding of a garbage system.
Displacement on Demand became Active Fuel Management then finally Dynamic Fuel Management.

It’s interesting that GM refuses to let go. They should have enough market research by now. If the 2027 version of the new engines still have it, it will be very telling.

Delete it or buy a 3/4 ton with the L8T, the L8T has no AFM/DOD.

The Government wont allow it. Theres rumors of a different system going forward, one that uses the rocker arm shaft as the means to disable the cylinder. I have seen similar on teardowns done on Ido car YT page but I dont recall what brand. Its likely we will see that sometime in the 2027's

I didn't realize the 3.0L Duramax has start/stop. That's nuts!

What site are you looking at?

I just pulled up the same truck. No mention of DOD/AFM. Since you’re in Canada - I suspect that you’re seeing trucks for the Canadian market, and not those being sold in the US.

The U.S. Chevrolet site shows AFM or DFM and Stop/Start on all gas engines for 2026 Silverado trucks as shown below.

Huh? GM 5.3L, 6.2L and 2.7L have DFM cylinder deactivation. Everything built 2020 thru now

Interesting. So, when you’re on that page, all the gas engines have it.

But when you look at a particular engine, it is not mentioned. So, which is correct? They all have it?

I captured this table from the Haley Chevrolet website, so it appears that all gassers have some form of cylinder deactivation (AFM or DFM).

I heard that diesels prefer to be kept running.
