Considering selling my special order GT

Danke.

Oh, wait, you live in New Zealand. Sorry.

It’s simply analytical.

Breaking the car is a reference to the core computer issue, which was more thoroughly detailed in a previous thread. Sometimes with the non-responsive throttle, the a10 trans will then have a violent clutch engagement and the rpms will either rev half way through the tach or rebound and nearly stall the car.

Almost sounds to me like your misinterpreting throttle lag for a transmission issue. I agree with Lou above. Get it checked. Nothing you are describing sounds normal.

I’m more looking to see if anyone else has experienced these issues or other issues that have driven them to the same feeling with their mustang. I know selling it wouldn’t be a smart financial move and skews the likelihood that I do end up selling in the near future to low

I have notice the throttle delay and it really pisses me off too. Just when you are trying to make a proper exit on a tight corner and you transition from brake to throttle ,the son-of-a-bitch falls on its damn face for about a half second. it sucks the joy right out of chasing that perfect corner. I have noticed it is less pronounced on sport mode. I have not had a chance to try it on a road course.

I would drive mine in sport mode more often but it refuses to upshift after I accelerate and just want to maintain the speed limit. It will hang at 3K rpm at 35mph and then refuse to upshift with the paddles for a good 1/4mile . The gear indictor just flashes like a middle finger to me while it refuses my commands.

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.

are you willing to take the 15-20k hit your used car with 20k+ miles will take? sounds like this is not the car for you. Nobody else seems to be having these problems.

 

[Awt2858]

He has 22k on the car. I think he should be used to it by now. Which begs the question...was this always an issue? Why wait this long to go to the dealer?

I’ve brought this up to the dealer in the past when they’ve had it for other things, such as corrosion replacement of the hood, complimentary oil change, tire replacement, and dealer keeps telling me there isn’t anything showing up in the computer. To look into it further they want the car for a week or more with no loaner given. Life hasn’t really given me a chance to be without four wheels long enough for the dealer to look further into it.
I’m going back to the dealership next week and will see if I can drive someone around and reproduce it.

Throttle response lag/delay is real, (throttle by wire) Some people notice it more than others and it is more pronounced with A10.

I have been awaiting the news today, FINALLY, a tune!!

Before you go losing $15K or more, I would spend the 1K and try the ProCal tune when it hits the market. It will address the throttle response and get more responsive in the 2K - 4K RPM range as well as wake the A10 up a bit.... If that does not do it for you, sell I guess.

It does seem to be beyond you.

I am OK with the nanny-like normal mode for my wife but I am not OK with the car not shifting when I command it to in any mode. The whole reason I avoid sport mode is because I am not able to make it shift when I want it to. It hangs out at high rpm like a dumbass while I am trying to get it to upshift under closed throttle. I don't want to drive around with the engine screaming in a 35mph zone. Track mode is overkill for spirited street driving.

Track mode is overkill for spirited street driving.

Track mode is more measured and less erratic than sport mode. The trottle mapping is designed for smooth and predictable trottle response coming in and out of corners. Sport mode just makes the car feel faster by front loading the throttle and holding the shifts longer. You should do some research on these drive modes.

Why do you feel like track mode is overkill?

I’m in the tune in camp … also I added HRE wheels and suspension mods to my S550 PP1… the lighter wheels made a nice difference in feedback

I wish I could have “liked” this post more than once.

I’ve had 8 or 9 new V-8 Mustangs since 2020, including GTs, Mach 1s and now Dark Horses. Never once, literally, have I ever not been in track mode in a single one of them except for a couple times when my wife wanted to drive a little. And I never will either. I’m pretty sure mine have all had some kind of high-zoot stereo system but I’ve never bothered to turn one on. I just want to hear that exhaust.

Hyper analytical tentative drivers should probably consider a more sedate car more suited to their personality types. Alternatively I’d suggest y’all put it in track mode and give it the beans. The term “throttle lag” will forever disappear from your vocabulary. I really just don’t understand why this is a 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 haven’t used track mode for any substantial period of time yet, at least not on the street. Even when I turn TC back on, the dash continues to display ESC, TC OFF icons and I don’t know which is true. It removes the predictability

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.
