Jailbreak ever?

[Teslawho]

So i know some teslas can be jailbroken (Ghost Tune) for more power and torque. Any ide if this will happen for the GTP? Im getting tired of just having ful power for 5 seconds at a time. Feel almost false advertised by ford when they gave hp/tq numbers when they should have added "power reduced after 5 seconds" I hope one day some can jailbreak these things to give full power at all times.

That would be nice. I would also like to know if there are ways to mod /edit things like the dashboard display like you can on a Lexus (can create you own gauge cluster look and layout/ graphics just like custom watch faces for smart watches).

If Ford went as far as limiting power output after 5 seconds of full throttle, knowing everyone would be pissed, it's probably for good reason - from a reliability perspective. I have zero interest in trying to jailbreak my GT for more power or longer sustained output. Sounds like a good way to cook your batteries, motors, or wiring.

Perhaps after drivetrain warranty has expired - I am confident the electronics would log any mods

One of my conspiracy theories is that Ford knew about the HVJB issue during pre production so they created the restriction. Imagine how many would have failed without the restriction. I think with the with upgraded boxes they should lift or extend the limits, so I would love to jailbreak. Coming from a GTI where you could go nuts, I miss it.

I can very confidently say that's not true. They had no idea how widespread the HVBJB issues would be ahead of time. The 5 sec power limit came early in development out of concern of overheating parts of the battery pack during very hot weather, not because of the HVBJB problems. They didn't have time to do all the precise thermal modeling before the release of the GT, so they put a very conservative thermal limit on it for the first couple model years. They underestimated how deeply unpopular it would be to GT customers, in retrospect the accurate thermal modeling should have been given higher priority earlier in the development process and should have been completed before launch. Hopefully they don't make that mistake again on future EV models.

Thanks, now I need a new conspiracy theory, back to the earth is flat meetings.
Yes bummer about the poor engineering in that regard, it means we are stuck like this.

Just curious, is there a thermal limit on the F150 lightning as well?

Logging mods? Have you seen how bad Ford software is? It took I don’t know how many OTAs just to stop OTAs from resetting saved radio stations (just to name one ridiculous flaw).

I’m willing to take that chance, as I have in every other car I’ve owned and modified.

It’s been almost a year and a half since the VP said “we will change that limit.” And whenever Ford is asked directly, they still hint that it’s in development.

Since no one has cooked their batteries, motors or wiring with the current limits. We can confidently say that there is plenty of margin for improvement.

Especially since the 2024 has a much less restrictive limit and has the same battery, same rear motor and a lot of the same wiring.

I mean I chose this over the model Y Performance thinking it be a better buy costing about the same n all. I don't think Tesla has these restrictions and if Ford is scared to give us full potential of car due to possible damage then I'm not sure Ford is ready for EV's and I bleed Ford. Have always owned Ford. 10 Fox Bodies and my current Cobra for reference. Hope Ford can help us out in this.

Does seem Ford has tossed 23’ & older to the side. Mr.Palmer doesn’t appear to be wanting to loosen up the power limits.

Palmer is about the only person who addressed it directly. He does want to loosen the limits.

Seems like the issue is elsewhere with Ford.

Pretty easy to lump this into a general “software issue” with Ford.

Look how long they are taking to roll out BC 1.3 OTA. And they started on that a YEAR ago……

Oh come on now - it’s not like anyone’s going to care about the performance of the battery powered Fiesta they’re developing in California or whatever ???

The 2024 GT does have the same battery as earlier models, but it has a different rear motor, slightly more robust wiring and cooling, but most importantly it has sensors throughout the entire electrical system to monitor heat. The new rear motor is the in-house developed motor used in the F 150 that is more powerful and more efficient than the earlier motor. These upgrades yield a longer range (280 compared to 260 miles), a 20% quicker fast charge from 10% to 80% and remove the 5 second limit.
For racing enthusiasts, the 2024 GTPE performs significantly better than the 2023 as demonstrated in this post:

P.S. The reason I looked into the differences is because my old 2022 Mach-E GTPE was totaled about 5 weeks ago and last week I got a 2024 GTPE to replace it. We were not injured in the crash because the car absorbed the energy of the collision. For day-to-day driving I don't notice a difference, but on a freeway entrance ramp near my house, I could get up to 80 mph if I floored the old car, while the new car can get up to 90.
