Hi folks

I want install the PSP from Suncoast, but my porsche dealer has never heard about this before and said it is not possible.

Does anybody have any material about step-per-step how it is done ?

Suncoast denied to help me at all. Said purchase first, we help later.

Since I have only 1 dealer in my country, cannot change dealer.

Thanks

It can be done, it's just a code that they give you to have the dealer feed into the ECU IIRC. You can add it or delete it. Not sure why Suncoast can't explain it to you. They won't actually help you do it until you pay them though.

Are you really sure you want it? You have driven a 718 that has it, right? I had it disabled on my Macan; much happier without it. Just saying.

Mitsuba

No have not driven any Porsche with PSP yet.
You have a point here.

today it feels heavier for parking, Harder than a M3, thats why I wanted it.

What does it actually do? If it is necessary why does the car not come with it already installed?

Dgkli

It is definitely not "necessary." These cars have power steering for gosh sake.

My own experience with power steering plus is limited to my Macan GTS and one 981 test drive. I've owned a 981 and now a 718 without it.

What it is supposed to do: reduce steering effort at low speeds. My perception on my Macan (and others have said similar things) is that not only does it reduce steering effort at low speeds, it seems to reduce steering feel at somewhat higher speeds. True or psychological, I can't say.

What I can say, though, is that it obscures feel at low speeds. What do I mean? When the road is slick (rain/snow/ice), steering resistance at low speeds gives a clue as to how much traction is available. PSP completely hides that.

The other thing is: 718s in particular, have really excellent steering feel (in the current EPS world we are stuck with), and I would not want to do anything that interferes with that. It's not as if it's hard to turn the steering wheel at parking lot speeds after all.

Personal taste prevails. My strong suggestion is, if you are not sure about PSP, don't assume you will like it: find a way to try it out.

That's just absolutely silly . It should be an on/off switch that comes standard then ... but I know Porsche .

My Mustang has the steering modes that are selectable for gosh sake. Comfort / Normal / Sport . I guess PSP is probably like "comfort" mode ?

OttawaSteve

No. Porsche has multiple modes as well. PSP is totally different. It is merely a boost to the power steering at low speeds. I have it on my car and I have driven a 981 without it. As far as I can tell, it does absolutely nothing beyond parking speeds, but does decrease effort at low speeds. Is it necessary? No, but for a few hundred bucks it is cheap by Porsche standards.

If someone has trouble with steering feel because of PSP, they are having trouble with feel, period. I was just hooning around a parking lot at very low speeds in the snow and the feel was excellent. YRMV.

One of the options I would never personally select.
Would also be a huge negative for me with a pre-owned Porsche. Unless it can be coded off somehow?

Dgkli

This is why Porsche offers so many options. And if you end up with PSP and you don't like it, you can always have it disabled. However, if someone is going to go to a lot of effort to add it (like the OP), then it is worth verifying first whether they will really like it.

I certainly would not include it on a "must have" list.

BTW, I've owned three Porsches, all with SC. I know some people have described a difference in steering feel depending on mode (Comfort/Sport/Sport Plus). I have never been able to detect any difference in steering feel depending on mode. (Unlike my wife's X3, for example, where the difference is quite obvious).

Dgkli

Yes, it can. I had this done on my Macan.

ANGST

Again , it's silly that it's just software to enable it . Should be standard and selectable as just another mode .

Mitsuba

Yes thats it. Its this part.

the only think they said that we buy the software license, provide the vin number and they will load the vin at PPN Porsche Partner Network system cloud, so your dealer can update your car. And again refused to send instructions to show to the dealer....

Called the dealer again. They accepted to give a try for USD 250 an hour ! Same cost of the item itself.... that I would have to purchase prior.

Guess I will drive and park several times another week and give another try before purchasing it.

Thanks for contribution guys

Most Porsche sales reps recommend getting it since it’s relatively inexpensive and will tell you it adds to resale lol, but honestly why do you need extra power in your power steering? It’s not like you’re driving an Alfa 4C....where you actually need it.

Archimedes

Exactly. PSP has been debated ad nauseum in the 991 forums. It doesn't affect the car's handling at speed at all and it doesn't magically turn a Porsche into a Lexus. It simply provides a little more assist at low speeds. I owned two Porsches simultaneously, one with - one without. I preferred the PSP for daily use, but didn't feel like I needed it. I considered adding it to the one without, but in the end I never felt I needed it enough to pay Suncoast for it and then the dealer to 'install' it. If it was free, I probably would have had the dealer turn it on in the car that didn't have it.

Do you need it? No. Is it nice to have if you daily your car? Yes.
