Anybody have a solution to get rid of the max 5sec power cut off

I would guess that Ford is busy trying to fix the HVBJB issue first, and make sure that the new contactors can handle 'normal' use including DCFC charging with 'repeated full throttle events' following.

Maybe after NORMAL use stops killing the cars, we will have some luck removing software caps on performance.

anyone have good numbers for 70-100 runs? That's where I find the Mache Most limited.

Doesn’t seem so. The GT has been out for 9 months and we still don’t have:

70-100 numbers
A roll race vs a 4X or ICE Mustang GT
A Dyno
A top speed run video in warm conditions (except a short clip on a private member’s Facebook page)
0-60 in 3.5 video
GT vs GTPE side by side race

Not sure if the novelty wore off or what. But it’s the first performance car I’ve owned where we have such a lack of data. My last car (Chevy SS sedan) had waaaaaay less on the road (2500 sold per yr) but tons of data available.

Edit: haven’t searched in a bit and found ONE of the above videos.

Side by side with ICE GT:

My solution to the 5 second limit:

Count your seconds slightly faster and it becomes a 6 second limit

3 second limit may be here soon the more GTs get bricked

Unlikely, unsubstantiated, and a little silly.

The 5 second limit will go away when Ford has enough real world data on the new contactors to remove it. Then everyone will be grumpy that the car doesn't go any faster at the end of 5 seconds than it did before.

Huh? ?

That’s just not how it works. No 5 second limit (gray bars) and it would be significantly faster after 5 seconds. The car is losing around 150 hp when the limit kicks in.

Hyperbole, a joke, a snarky comment. At the end of 5 seconds of full power, the car will be going the same speed whether there is a limit or not. At 5.1 seconds the difference appears. Some folks will complain that the car isn't faster at 4.9 seconds.

Ah… I see what you did there. ?

Maybe should have said “by the end” instead of “at the end,” but either way I get it now. English is a complicated language when the same sentence or even word can mean the opposite depending on how you read it.

I wonder if the GTs they sold to the NYC police department are limited as well? Might be a good idea to compare asbuilts to see what differences there may be in the settings.

Anybody know the C rating of the MME battery pack? I've loosely heard 1C for Bolt, 2C for ID.4, and 3C for Model 3. No idea about the Mach-E's max C rating.

The C rating is correlated with the IR number which I've seen posted here as 33 miliOhms.

This guy proposes mixing battery chemistries.



Like 1 kWh extra pack rated at 10C so that provides a 10 kW boost when necessary. Seems complicated... but it could work.

i.e 5 kWh 10C pack that provides a short 50 kW (which quite a bit of power) boost to the motors. Mixing and matching batteries with slightly different voltages + amps isn't simply though.

Maybe after NORMAL use stops killing the cars, we will have some luck removing software caps on performance.

"NORMAL" use is not back-to-back 5 second full-current pulls. I want to see Ford address this and get it up to at least 10-15 seconds of full power, but lets not kid ourselves - this is for fun - not any kind of real-world daily driving usage scenario.

Not a good idea. If you make a mistake at these voltages it can result in an explosion.
