Part 3: The Quest for the Perfect Tune

[taycan_bud]

And do you feel a difference in normal driving, when you want to take over a car at a speed from 50-100?

Purely anecdotal but yes, the acceleration now feels very linear at speeds past 50 mph.

I also meant to add that the motors make a very nice growl when I mat the throttle. Maybe that was present before but don't think so

I believe someone put it best a couple posts up, but it feels a bit unreal how much more powerful it is while moving. It feels like an entirely different car when you step on it while moving. Up until about 70%+ throttle, it feels OEM, with much better throttle response. But once you get the pedal close to the floor, its literally like Clark Kent ripping his shirt open to reveal the S. It pulls so much harder in such a visceral manner that its scary.

So visceral. I find myself needing to really mentally prepare before I push the whoosh pedal, things happen at a pace that my brain has not experienced previously.

Another happy Mapev customer here. 2025 S e-tron GT without tune 10.87 at 128.40 mph quarter mile.

With tune, [email protected] mph. These times were on an asphalt stretch of road.

At the drag strip, [email protected] mph. Car is stock other than the tune.

Would like to try bracket racing, could you setup the tune so I could dial in the level of power I want to run. Something like 90% of max power, but i would like to be able to input that value myself depending on desired time and track conditions.

Input it where though?

Man that is an awesome time and massive improvement. Any tire spin or is it hooking strong on launch ?

 

[stmang]

Good point, didn't think about how to enter the parameter.

It hooks perfect. Foot on the brake, then accelerator to the floor. I'm amazed how well launch control works. Stock 20 inch wheels and tires at 42 psi. I don't think drag radials would hook any better. You can't do a proper burnout to get any heat into the tires.

Anyway, I got exactly what I wanted with the tune which is a sub 10 second quarter mile.

That's the highest form of flattery

What level of regen are you running on your Turbo S Dmitri?

I always used Auto. I don't have my Turbo S anymore though, waiting for the J1.2 to arrive.

 

[gregeast]

Congrats on the J1.2! What trim?

So stock level of regen? I know you experimented with higher levels, was just curious what you settled on.

This is the spec:

I never used the regen, only the "Auto" one, which has quite high level of regen when there is something in front of you. Otherwise I prefer to use the brakes to slow the car.

My preference is irrelevant though, I do whatever people ask for, it's just the Taycan was built to be used with the brakes first and foremost, and the accelerator is quite stiff. I think with a softer spring in the accelerator a more OPD style experience could be viable as well.

Well after taking longer to power up the laptop and clear faults than to change the module, my MapEV box is fitted. Was so easy.
And then took it to work today......So pulled out and thought i'd give it a quick boot away from the house, and was initially a bit disappointed with the increase and then realised that the front wheels were spinning and pulling the power back.
a few miles down the road, opened it up from 40mph, and OMG, then doing 3 figures!
I would say it doesnt "seem" to hit much harder than before, probably because its smoother than before, it changes gear later and smoother, but the speedo is a massive indicator of how much faster it is. I've not had change to time it or anything yet, but i can say accelerating from following a HGV at 56mph and doing well in excess of 3 figures by the time i've overtook it, was quite mindblowing.

Does anyone with a Taycan GTS (2021–2024) running the MapEV tune have real measured 0-100 km/h and 0-200 km/h times?

I’ve seen MapEV mention ~2.8 s 0-100, but haven’t found confirmed user data.
Thanks in advance for any numbers you can share!
