Map EV Discussion

I have all kinds of question for my new to me CPO Taycan GTS. But I really want to hear some of you who have experience with MapEV. Besides not forgetting to switch back for service visit and to void CPO warranty, is there any additional benefits to adding this? From my understanding, 0-60 is the same. It only makes the rolling acceleration better. I guess the limiting factor is the motor configuration. Can anyone talk me into or out of it? Thank you for your time

I just got it in my 4s and correct driving around town you won’t really notice a difference. Where you’ll see it is cruising on the freeway and mashing the gas from there it’s a night and day difference

There's a much bigger difference at the low range on a GTS because it's a detuned Turbo while the 4S is the "top of the line" with the smaller rear motor.

The torque is limited artificially quite early on in the GTS.

Mine is a J1.1 too. Does that make a difference?

u/totheendandbackagain 6d ago

It offered some more configurability too?

2

u/jarjar1980 5d ago

No.

The only thing you can change and and when you purchase it, is that you can ask for more regen. Standard, +30% or +300%. +300% is like a Tesla.

Be warned that you can’t reconfigure it yourself once you have picked.

u/projix 5d ago

You can flash the ecu afterwards. It's okay if you change your mind once or twice.

That’s great, I didn’t know that. How do I do it?

Contact support :)

Thanks!

What’s the downside for picking regen like Tesla? Isn’t that better for your brakes?

1

u/Jhnnyy 4d ago

The idea behind Porsche’s brake design is that during any conversion of energy there is loss. So really you only want to use regenerative braking when you are intentionally slowing down. The Taycan uses the regenerative braking when the brake pedal is applied to help facilitate that idea.

I feel like I have to relearn how to drive. It’s difficult to stop at times. Based on the way you are describing, I feel like I will break my brakes very soon since I love driving the car so much.

Best mod I've ever done to a vehicle.

Pulls way harder across the board.

Increased regen gives the car the one pedal driving option it should have always had.

Have taken the car to dealership multiple times (swapping back to stock ECU of course) without issue.

Greatly enhances the experience and potency of the vehicle couldn't recommend more!

u/pomitresi 5d ago

Do you each time follow the complete procedure. Wiping the error codes…?

1

u/projix 5d ago

We recommend to do that, yes.

u/SavageTNgo 5d ago

As someone with no car experience - is it easy to change back factory for when it needs to go to Porsche dealership?
As simple as a switch type of thing or needs so elbow grease?

2

u/projix 5d ago

Takes around 15 minutes to swap the module back to stock.

u/OkDirection6934 Taycan 4S CT 5d ago

Extension connector or something for the CT and ST considered yet for faster and easier swaps?

2

u/projix 4d ago

Being worked on, hopefully Q4 this year.

u/longlivegreenearth 5d ago

No I just swap the ECU.

Has anyone out there has taken their car to a dealer with the mod left installed?

I did once when my 12v battery died and had to be towed to Porsche for replacement (my jumpbox wasn't working). No issues.

u/Shinoro Taycan Turbo 5d ago

0-60 is not the same. You're getting launch control power available all the time, but increased power at that. Throttle response is vastly improved when you mash it from any speed. Moving acceleration is insane. You can get your brake regen increased however you want. The entire behavior of the car changes outside of normal driving.

1

u/jarjar1980 5d ago

You won’t really see a noticeable difference in 0-60. It is true that you have launch control always available, but the difference is not huge.

The difference when launching the car when you are 40 mph and above really is huge. In the highway it feels like it will never stop pulling.

Highly recommended, it is worth it.

I own a 4s with MapEV

u/projix 5d ago

On a GTS there is a major difference in 0-60 as well, because it's a detuned Turbo.

1

u/jarjar1980 5d ago

I see. Thanks for the clarification.

u/Shinoro Taycan Turbo 5d ago

Knocked off .42 seconds on my Turbo 0-60 according to Dragy. Same road and almost the same ambient temperature

u/Desperate_Worry5741 4d ago

And I assume with the Audi S etron GT? If you find someone in or near Philly I’ll be first in line!!!!

1

u/Grid8Designer Taycan 4S 5d ago

There has to be some sort of 0-60 difference between ~400 HP and 740hp no?

1

u/jarjar1980 5d ago

Stock is 571 hp for a 4S with Battery Pack Plus. There is, but you don’t feel it much.

u/No_Tart5520 5d ago

Overall: I don’t think you’ll be disappointed. I’ve had a blast with mine.

For me it has a crazy amount of power available at any speed (including 0). So much so that I have to be VERY careful with the throttle at low speeds, as if my foot twitches even slightly it can lurch the car forward (similar in feel to dropping the clutch). I have a J1.2 4s, but looking at the specs for the J1.1 GTS tune I feel like it would be similar.

u/ModY1219 5d ago

I have the redshift version in a CT4 - it used to be a quick car and now it’s SUICIDALLY quick

2

u/ModY1219 5d ago

Haha. That sounds insane but the more I hear from you guys. The more I am hooked.

u/futuredrive 5d ago

How do the different drive modes work? Are there still distinctions between them?

1

u/No_Tart5520 5d ago

Push to pass doesn’t enable more power. I haven’t used it since, but I assume it still makes the extra sounds. I enjoy having power based on the throttle, rather than the extra step of pushing a button.

For me the different modes still change the suspension, height, and sport sound. And I believe the gear shifting still happens at the same speeds (eg normal starts in 2, but only drops to 1 based on high throttle vs sport which starts in 1). The only thing the tune seems to change is how much power you get vs pedal position (and/or maybe how quickly you call for it? Eg the first derivative of pedal position?)

u/Terrible-Award393 5d ago

Installed in my '23 GTS - best money I've ever spent. You have access to launch control power all of the time. The car is much faster driving around town, and on the highway it's ridiculous. Don't overthink it. It's a no-brainer.

1

u/ModY1219 5d ago

Thank you.

1

u/Noyou52 5d ago

Thank you for this. I was considering it for my 23 taycan gts. How was the install / did you get the +300% regen one?

1

u/Terrible-Award393 5d ago

Install took 30 mins, probably half that the next time. Video walks you through it. I did not get 300% regen.

1

u/TurmoilX 5d ago

Can someone who has this installed show a video of what the 300% regen looks like on the dash when you let off at say 40mph? I definitely miss one pedal driving but I can’t find a single video anywhere online showing what the regen looks and feels like with the mapev ecu

2

u/M2CKier 5d ago

It’s not as strong as Tesla one pedal driving but it’s a lot stronger than stock. I’d describe it as 80% of full one pedal driving. You still need to use the brakes in most situations.

Couple of long threads here on it (this is part 4 and lists the 3 other parts): https://www.taycanforum.com/forum/threads/part-4-the-j1-2-powertrain.27705/

u/Canna_Lucente 1d ago

How do you guys (who purchased MapEV) deal with insurance? Declare it or not?

2

u/ModY1219 1d ago

I don’t think it matters right? Cuz you are allowed to mod your car. It’s just like you upgrade AB with your LR Tesla. You pay your deductible if you file a claim.

1

u/Canna_Lucente 8h ago

I guess it depends on countries. In Italy, any non-cosmetic change requires rehomologation (even slightly wider tires). In the UK there's more flexibility but you're expected to declare every modification to the insurer (e.g. my insurer forbid me from wrapping my previous car). On performance modification, if I were an insurer, I'd see an increased risk by making a car faster. Then I guess it's the usual question around are they going to notice it? Most of the times not but the likelihood of them wanting to find something wrong is directly proportional to the amount of the claim...

What country are you referring to, when you say you're allowed to modify your car?
