Redshift vs MapEV

[prj]

any distributor in Northern California?

I recommend contacting the US HQ (EFI Motorsport), as they handle all the distribution in the US (all other distributors and installers). The MapEV HQ distribution reach terminates with them, so I can not really give good information about US distribution here. All I know is we have no large distributors in CA, otherwise they would be on the website, however there can be installers who are not listed.

You can either e-mail info at mapev net, in which case a ticket will be created and assigned to them, or you can contact EFI Motorsport directly:

Their e-mail and phone number are listed on that link.

I would buy it in a heartbeat, but it doesn't do much for a j1 rwd unfortunately. The price is reasonable, down right inexpensive for a porsche product.

I have an RWD PB+ 2025 and even when it’s a little moist outside it feels like driving on ice, let alone full wet, like it’s everyday here during fall and winter. Getting more torque and HP would not help imo. How do you feel about that in your RWD with the mapping?

I use MapEV to tune my Taycan RWD with the standard 79 kWh battery.
The overall results are excellent the response is much quicker, and especially with gear shifts now happening at around 125 km/h, the difference is huge!
The real-time support provided on the backend is truly priceless.

Got, install isn’t complicated and I am pretty handy it is more who I can buy from. Let me send email and start from there

The 100hp extra is quite noticeable under way (with the PB+), percentage wise it's a 26% increase and for the car that actually needs extra power the most that's really not bad at all, it's about the same percentage increase as the Turbo gets. For the small battery it's day and night though (47% increase), thats like GTS+ levels of difference.

Having driven the RWD with and without tune I would really not say "doesn't do much". I mean yeah, it doesn't double the power like on a Taycan 4, but the increase is very nice, and better than what you get when remapping most gasoline cars!

@prj thanks for all the responses on this thread. I am convinced and placed an order

Do you have a list of all the parameters that can be customized? For example I wasn't aware regen can be customized in each mode, which I learned from the other responses in the thread.

Also, can the settings be applied only before shipping the unit or can it be adjusted after install "over the air"?

Regen can't really be customized in each mode on the Taycan, at least if you want to keep the original functionality.

The original functionality is that you have three states "on", "off" and "auto", and these states are changed by the PCM. When you change modes in the PCM each mode just has regen assigned to it, e.g. sport plus has it on by default. Individual you can customize it.
But it's not "per mode" in the sense that there's just on/off/auto and the PCM tells the ASG what to run.

It is possible to kill this functionality in the ASG and actually assign the different regen maps to drive modes, but then the on/off will do nothing and only "auto" will be different. Counter intuitive.

What can be changed is power per mode, but I don't recommend it, there's already a huge distinction between normal/sport after the tune, as the stock mapping tries to "hide" the gearshift by running the front motor 100% for it's duration, whereas with the tune the front motor is already running at 100% so the shift can be felt more.

Our standard offer is the best, that's the one I recommend personally. Regen is a mixed bag, we have a slightly increased option and then a massively increased option, that's just preference, I can't tell you what's right or wrong.
The ASG is responsible for torque coordination (positive and negative i.e. regen) and controlling the gearbox. Everything related to that can be altered - but should it? Some things are preferential for others (e.g. shift point at wide open throttle) there's an optimal value that's already set by us.

Also, can the settings be applied only before shipping the unit or can it be adjusted after install "over the air"?

We can reflash (and have done many times) the ECU when it's installed in the customer's car, there's a special tool for that (MapEV Flash), that gets the file from the server for your car and flashes it.
That's one of the benefits - you don't need to ship the ECU back and forth.

My apology, but I must of misinterpret the graph that you posted. I was under the assumption that porche pretty maxed out the rwd motor from the factory. Do you have any real world acceleration time between stock and tune rwd PB+ cars? Thanks

The gearshift is at ~130km/h. Majority of the difference is above 60km/h. It accelerates 25% faster after that. So if your 100-200 time is e.g. 14 seconds, you would expect around 11.5 seconds with the tune.

I don't think I have actual Dragy measurements from a RWD, but we've done quite a few and people have been satisfied with the result.

Maybe this graph is more interesting:

I'd say the difference is fairly significant at higher RPM. It shifts at 125-130km/h with the tune, which is around 15500 rpm on the chart, and after the shift is complete you're right at 8000 rpm again, where you have the extra power.

Depends really how you drive it, if you just drive it around town, then there's not much to it, but out of town there is significantly more performance for overtaking and merging onto the highway.

Just depends on your usage I guess

@prj, you mentioned:

Regen is a mixed bag, we have a slightly increased option and then a massively increased option, that's just preference, I can't tell you what's right or wrong.

So if I were to order a MapEV tune, I could choose to have slightly more regen than stock, or massively increased regen from stock? Does the latter option approach a "one-pedal driving" situation, in that the car will nearly come to stop via regen? With the massively increased option, is it enough that the car's brake lights should come on during regen? And if so, do they? I know with cars having a "one-pedal driving" mode (like my BMW iX, for example) the brake lights come on during regen, but for the Taycan, which doesn't have that mode and seemingly wasn't really designed for regen to slow the car down all that much, wondering if the brake lights will come on or not... I definitely like the idea of more regen, but not at the expense of safety - as I don't trust the driver behind me on the freeway to not be texting away at 70+ mph, not paying attention, ...

Many thanks,

Brian

I personally think that MapEV tune regen is very similar to standard and behaves how a sports car should within the constraints of an EV. One pedal driving as mentioned in other threads should be reserved for Tesla’s and other non sporty EVs

 

[Emm]

I have the MapEV tune on my 2023 GTS ST and can absolutely recommend it.

Another parameter if you're in Europe, apart from the technical and pricing aspects, is how keen you are to purchase from the US right now—speaking for myself I try to "vote with my wallet" and thus currently avoid US products almost as must as Chinese products, given the current anti-democratic anti-Ukraine US regime (apologies for bringing up a political issue here, but for me as a pro-democratic European it's a very important aspect that also spoke in favour of MapEV :–).

Of course they come on. If you use the auto mode they come on as well from factory.
Brake lights on all EV's are based on the deceleration in G, it does not matter from which source it comes. As soon as the car is decelerating more than X amount then it switches the brake lights on.

Yes.

Is mine broken then? I will test again tonight but my brake lights only come on when the brake pedal is pressed regardless of pressure or G. In auto mode the car can slow faster than brakes and still non rear lights

Pretty sure they do come on in auto mode. I remember seeing that on my Turbo S, and there's a whole module in ASG for it iirc.
