Part 3: The Quest for the Perfect Tune

[prj]

My car concerns a TS CT. Does it mean I always need to drive with stiff dampers?

No, absolutely not, this happens only momentarily when the throttle is >99%.

or can I still drive in a "comfort" modus while having max torque and power?

See above. If your throttle is not completely to the floor then nothing is affected.

Got it, clear thanks.
When its floored, that's fine as there is simply more "normal" driving than flooring it.

And when flooring it, power delivery for the TS is continously no? (Not only for 2.5s like during launch mode without the tune).

Soon of to the dealers for 60k service...thereafter, if I keep this car, to consider this tune seriously). Just a pity personally that 100-200 is limited (due to hardware limitations, not your tune)

You get the power all the time, but the inverter extra torque is limited to a timed burst. However in a Turbo S by the time the burst runs out you're already below the torque on the inverters anyway. Basically for all practical intents and purposes it's permanent.

Quick question, will this screen reflect the new higher power levels once the controller is installed? Also something else I’ve noticed, if the push to pass is activated at low speeds (probably the same at all speeds) the suspension becomes rock solid, like much harder than even sports plus. No idea why Porsche did this, i pulled the push to pass lever on the steering wheel by mistake earlier at like 10mph on a bumpy road and the car became nearly undrivable.

Update about this - it actually doesn't change the power.
The power does not come from the ASG, it's coded in the PCM. I think you might need PIWIS Engineering to code that to a different value though.
This is how it works on other Porsches.

So this is not something we can change with our modified controller.

I got the MapEV tune for my 2025 Turbo GT Weissach and couldn’t be happier. 0-60 MPH is coming in at 1.96 seconds (1.80 with 1’ rollout), 1/4 mile in 9.05s @ 152+ MPH! Car is also a rocket from a roll now. Previously it was doing 5.1s 60-130 MPH, it’s now 4.5!

Amazing results, need to get myself a Turbo GT asap! Fitted this to a 2025 J1.2 GTS a couple of days ago. Took me about 20 mins to fit as I was very careful not to damage any clips etc.

Car feels awesome and Dmitri has been very accommodating with a few over the air tweaks (extra regen etc). Been having issues with my Draggy as I have the acoustic glass, will probably end up gaffer taping it to the roof unless anyone has any other suggestions?

Took a quick run using the performance app in Car Scanner. No idea how accurate this is but the figure it gave me feels believable. Will post again when I get Draggy working.

Awesome results for the GTS!

I also had issues with Dragy not being able to acquire satellite signals. The trick was to mount it on the rear wind screen. If you have the Draggy Pro, you can use the mount that comes with it. Works like a charm!

Huge 60-130 improvement on a roll. How does that compare to your Plaid?

Will give that a try, thanks for the tip!

Amazing!. Is that on the street?.

How much regen did you add, and how would you describe the difference? (Myself I initially wanted +40%, then went down to +20% to not make too much of a change, and then wound up making no changes to regen as per Dmitri’s recommendation.)

Been having issues with my Draggy as I have the acoustic glass, will probably end up gaffer taping it to the roof unless anyone has any other suggestions?

I also have the insulation glass, and my solution has been to roll down the window and hold the unit through the window while accelerating – not ideal, but at least I got the original Porsche figure (0-100 km/h at 3.69 sec; before the tune, that is, as I haven't installed it yet).

Took a quick run using the performance app in Car Scanner. No idea how accurate this is but the figure it gave me feels believable. Will post again when I get Draggy working.

0-60 at 2.5 sec sounds terrific, if correct; if so I'm guessing 0-100 km/h would be at around 2.7 sec, which also sounds great (myself I’m happy if I can go below 3.0 sec, as I have the J1.1 GTS with lots of factory options, weighing in at around 2.500 kg).

Went with 30% extra regen as per Dmitri’s recommendation as a max due to brake blending issues if set higher. It’s noticeable but not night and day.

If you change your mind we can always flash the controller remote and add it. No worries.

Thank you!
Time to also post the Taycan GT curves on the website.

btw another interesting tidbit about the Taycan GT- the gear ratios are different from all the other cars.
That's also why it's so much faster.

Doesn't it the Turbo GT shift at 72mph?

Shift start is around there yeah, but shift end is higher.

That's already a huge clue because for the Turbo S J1.1 with all the extra torque the optimal shift is around 50 mph.

I was bummed as to what was going on until I saw the gear ratios being shorter in the software. So it means the rear assembly is unique.
