DFM delete

[giveymore]

Hey, I have a 2022 ZR2 and hate the DFM system. I bought the 6.2 to have the power of 8 cylinders running all the time. I didn’t get the 6.2 to save on gas. I checked in on the Pulsar LT system but they responded that they did to have a solution for the refreshed 2022 and up with the 10 speed transmission. I am currently running in L9 all the time. Anyone have a solution?

Or leave it in trailer mode. I also checked on the Pulsar.

Honestly, I doubt that Edge products is going to put the effort needed into cracking this Global 2 code. It's been a long time now and I see a trend toward selling more turbo 4 cylinder & diesel models. Add to the fact that the truck still has those weird lifters in the engine. With all the diesel technology they are working on, I think the 6.2 liter is small beans. I hope that I am wrong.

Same conclusions here was looking into the pulsar but being that 5 or higher (refreshed), means I’d be throwing money away. What are they referring to as “refreshed” out of curiosity

L9 and tow/haul ON. Shifts/sounds/better driving experience. Forget the add on crap.

All the electronics and tech were changed, but the bodies and chassis were largely the same.

Sounds much better just in tow mode!

Is that any different than just turning it off every time you start the truck?

You may be thinking of the auto start stop. That can easily be done away with by installing a module. There 's several threads on here about it. The L9 / tow haul mode is to keep the cylinder de - activation from kicking in. Two different systems.

Check out "DONSLIFE" YouTube channel and search for videos on the DFM system. He goes over it in detail. He has an AT4x with the 6.2. ( same engine.) He did a bit of research to put together the videos and has some good information. It seems the DFM randomly alternates the cylinders and the computer does a good job at it. He also points out that The DFM is not the big issue, but the lifters and if you have bad lifters... you have bad lifters... From what I understand they are phasing out the DFM on 23 models and up

I hope they do! I think they are also trying to sell more small diesels and turb four cylinders, to improve their CAFE points numbers.

Cause they ran out of 6.2Ls and parts to fix them.......LOL

At least we got a real engine! Soon they are forcing electric on everyone.
Did you hear about the por sap that bought a Ford lightning and and started out on a cross-country trip and ended up getting a rental to finish his family vacation. I kind of feel bad for him but he's the knucklehead that bought the electric truck to start with.

Hey guys,
remember the Corvette and Camaro have this same 6.2 engine and DFM, so Edge might not be out. The micro-chip shortage has the 5.3 engine with all the components but no DFM modulation/ activation since the 2022 refresh. The 6.2 has not had that shortfall from what I was told and they all still have it.

Wouldn't that change the transmissions shifting which wouldn't be good either?

Why would that create an issue? Not sure where your concerns coming from?

If you run L9, the transmission will also cycle through the gears according to speed. So if you come to a stop, it's not gonna start in L9. It'll start in L1 and work it's way up as though you were in auto. It shifts fine like that.

100% no. L9 and trailer mode create more spry shift points which have zero negative effect.

100% correct my friend! And I love the TOW mode shift points far better than normal drive mode. All I ever use is TOW mode
