Considering selling my special order GT

[Awt2858]

Its highly possible its a condition that exists outside of your driving habits.

ICE is notoriously inefficient at lower rpm and colder temperatures. Its likely that under certain specific criteria the ecu alters the throttle in a way that creates this lag, so as to keep the engine running 'clean', if that makes sense.

Not saying this specific example is happening, but imagine stabbing the throttle from a dig. If your pedal was directly wired to the throttle, there would be a very split second where the car burns a sub-prime or unevenly mixed fuel mixture. Instead, the ecu could more slowly reel that throttle open, it would allow a more smooth flow and mix. This is probably why there's rev-hang in modern manuals as well.

my 2 cents

I’m thinking it is something right along the lines of what you’re describing that is causing the delay problem

If you have your drive mode set to Sport, move your shift lever into M if you are okay with paddling all the gear changes and it will then allow you to upshift at will. Not the case if in Sport and D

I would use M more often if it did not have paddle shifters. Trying to shift while also turning the steering wheel is annoying. It is difficult to hit the paddles because they spin with the wheel. It would be far better if the shifter were on the stick where you hit it side to side to up and down shift. Even when using the manual mode the shifts are not as precise and predictable as they should be. they should be nearly instant and always the same time delay, not sometimes instant and sometimes .5 - 1.0 second delay.

With all due respect, the car comes with different drive modes for a reason, and you aren't using them appropriately. Why you would drive like that in normal mode and expect a different outcome is beyond me. If you want linear throttle response coming out of corners and transitioning from brake to throttle, you need to be in track mode. Don't blame the car for user error.

Just be aware that "track mode" switches off all the nannies like electronic stability control.

I tend to use sport mode for that reason. It loosens up the nannies, gives higher rpm and instant throttle response, but electronic stability control is still there to help out if you get over your head.

I would pay for tunning to fix these "flaws" in control and precision if they could. The car has plenty of power and capability to please just about anyone. What it lacks is precise control of the throttle and transmission. It may come down to emissions in some cases. Maybe track mode works better because they are allowed to produce more emissions than when on EPA controlled public roads.

On public roads, esc is a good safety net to have. Unlike track driving, public driving has many more variables

It also appears that in Track Mode, the throttle response is not as sharp as it is in Sport. Although I like the downshifts and rev matching in track mode. My custom setup is always in Sport.

My first day on the track, I ran Sport Mode. I was surprised at how well it performed left in D.

My first day tracking this car I also ran mostly Sport and was happy with the powertrain response. I did prefer leaving it in M instead of D. The customizable gauge set on the infotainment screen was very handy, and thankfully kept my selected gauges in the same spots between sessions.

In my case I’d accept the term “analytical,” but I think “tentative” is inaccurate.
I’m still not sure “throttle lag” is the most accurate term for this but that’s the most symptomatically matching term, the easiest to convey. Maybe more accurately a computer processing delay; something like ECU - TCM taking data input from driver action, following the almighty algorithm of prediction of next action and following system procedures to execute predicted next action, then unable to take action on a driver input different than predicted by the ECU-tcm. That could result in more time taken to re-evaluate the input vs expected action, change each system to accommodate actual input and execute the drivers input, sometimes with violent result.
Again, this is majorly problematic not just because it’s something Ford has the ability to fix through OTA update but also because if this happens at an inopportune time, someone will get hurt.

Maybe. As I mentioned I’m old, perhaps with the attendant reflex diminution age supposedly brings. And I enjoy rolling pretty hard. Yet amazingly I’ve escaped serious bodily harm thus far.

There have certainly been a few important safety developments over the years that have saved many lives. Airbags and ABS spring immediately to mind. But I’m left speechless when folks praise and worse yet rely on involuntary nannies and other mitigation strategies. Perhaps I like to actually drive the car too much and am willing to be responsible for my own actions. Come to think of it this might be more of a discussion about social and governance evolution than automotive design.

It does not switch off "ALL" the nanies.

I think I have had a similar issue in a different car (not my Mustang)... if I came to a stop, and then immediately tried to give it gas, it would have a short hesitation. Perhaps the trans not shifting to 1st quick enough... not sure what it was exactly, though a tune (with transmission tune) seemed to nearly eliminate the issue.

Traded it in for manual you’ll be fully engaged with the car and the only lag will come from your left foot, i’ve had my GT for six months, so much fun to drive.

Sorry - I did not know. What does it leave on?


EDIT: Owner's manual says they are still on but much less likely to intervene.

See especially ZXMustang's graph of the four various pedal inputs in the 2024 file depending upon mode selected. Interesting stuff.

My hesitation with any tuning is that I’ve got a lifetime powertrain warranty and I do plan on using that warranty in the future. I’m afraid any sign of a tune in the computer’s log or history would invalidate that warranty
