Don't know who invented this piece of chit, but it's the most annoying thing on a new vehicle.
I'm sure it was meant for mileage ratings.
I have the option of turning it off but need to do it every time I drive, wish there was a way to permanently disengage it.
Just an old mans rant.
I agree 100%. I bought a Pulsar engine tuner for my 2020 GMC and permanently disabled it. The only reason I ever want my engine to shut off is because I turn it off.
I bought the Pulsar LT for my 2021 GMC. I bought it to turn off the DFM. By doing that, the auto stop start is also disabled. It's not really a program change as much as it is a signal bypass. My truck now runs on all 8 cylinders all of the time. Throttle response was also adjusted. Runs like a different truck. Also, by running on all 8 all of the time, there is no lag when trying to pass on the interstate. If truck was running at reduced cylinders, there was a delay in pulling out of that mode, and then finding the right gears. One of the better investments I've made.
