EV throttle response

[JackSparrow]

I would think that PRJ could provide you with a linear torque mapping for the accelerator.
I agree about the non-linearity, my other EV, a 2021 Volvo XC40, has way more aggressive and progressive torque delivery. Since it has no launch control, it gives full access to all available power all the time, which is why I’d probably like the Mapev tune.
I’ve had other ICE cars that had a linear aggressive torque response, in my case V8/manual, and they are not jerky or hard to control, and they don’t just give you all of the available power at tip in. It’s easier to experience it than to explain it.

OUR other EV is a Genesis GV60 Performance. Instead of Launch Control, it has a “Boost” button on the steering wheel that gives a 10-second 64HP boost. Interestingly, the button be pressed again as soon as the 10-second timer expires. This “feature” drives (ha!) me crazy - just give me all of the available power all the time and let me control it via the accelerator pedal - don’t hide the performance behind launch control or a special button that I have to remember to press!

Has anyone tried this:

or one of the other pedal response controllers?

There’s another thread where someone is selling one, you could probably DM them.

Is it more linear or is it still very muted for the first half of the pedal movement?

Try this experiment- from a stop in 1st gear, ease into the throttle and keep increasing pressure until you’re floored.

In my 4S if you do this for the first half of pedal movement the car isn’t that quick then you hit some threshold around 50% throttle and it all of a sudden takes off. The difference above that point and totally floored isn’t that much.

I’m actually half tempted to buy one of those cheap “tuners” that just adjust throttle input settings.

Something like this:

"Try this experiment- from a stop in 1st gear, ease into the throttle and keep increasing pressure until you’re floored."

This quote made me laugh out loud, I tried all the ways but the moment I get deeper in the pedal the car just takes off, progressively and without pause.
Second gear kicks in seamlessly and it just keeps on going.
Maybe it's me but If I do as you suggest the numbers are (allegedly) in the three digits before I can even take a breath.
I've never done a launch control.
I do like the progressive pedal, so it's slowly slowly nice and relaxed in traffic and car parks, but if I get some open road and push harder the blood is going out of my head.
It could be a 4S thing, as suggested you may wish to try a turbo (S)........

That’s exactly the point, about halfway through the pedal movement it just explodes with acceleration.

There is no “middle ground.”

It’s sluggish for the first part of pedal travel and explosive past that.

Not easy to control the middle ground of brisk, but not floored acceleration.

Personal preference, but I think it’s too slow at first and too fast in the middle. Would prefer linear throttle response.

In a gas car it’s extremely easy to get cars to respond how you want. Want to shift at 2k, 3k, 4k etc? No problem. Only exception is when they program a transmission to be fuel efficient, then downshift the right amount can be difficult….. ie crusing in 7th gear and wanting to shift to 3rd, it won’t always end up in the gear you want except when floored.

Better yet is to hide 20% of the power behind a "push to pass" button that can only be added after buying a stupid $1200 clock that sits atop the dash that is always staring at you!

I drive the humble base RWD and I'm happy with it - if I want a quicker response, I have the optional Sport Chrono package, and dial in Sports or Sports Plus. But as this is my daily driver, I'm happy with Normal 90% of the time.

Just a thought, are you driving in high heels ?

I fully agree with this description—I'm fine with a somewhat "sluggish" response at the lower end of gas pedal pressure, and then instantaneous response at the higher end of gas pedal pressure, but there is no middle ground where it is responsive around the middle; it just goes from low-end sluggish to high-end instantaneous like flipping a switch. I too would like more immediate (but not instantaneous) response around the middle section of gas pedal pressure (i.e. more like the behaviour in my current RS6 and most other ICE sports cars I've had).

1. Drive it in Sport. Half of what you guys are describing is probably the gearbox shifting 2->1. Drive it at least in sport to avoid that.
2. I did change the throttle curve on my FL Taycan 4 to match the Turbo S, because it felt sluggish otherwise at the lower end. By default none of our tunes do that, we just extrapolate it up, as changing the default feel of the car is not the best thing to do.
3. The throttle maps are not linear by any stretch of the imagination. They all have the low speed boost that any car has. This is the J1.1 4S:

And this is the J1.1 Turbo S in comparison:

The notch is very similar, but on the Turbo S you just have more request, because the range the pedal has to cover is bigger. There is a slight "lull" in torque request increase around the 50% mark at lower speeds after the initial "boost" ramp.

Note that on the 4S it makes no sense to request as much torque at low speed, as the rear motor is physically incapable of producing it anyway.

Switching between modes does not change the throttle mapping, it only changes the amount of filtering applied.

Does this mean people with your tune can get an even more aggressive lower end?
