Do you know if they got the error the rest of us see?
I would suspect maybe their has later model steering software?
Got the answer back from the shop just now. They said they just changed the option and it worked with no errors. The tech drove it around for only a short bit but but he said the steering definitely felt different.
I have power steering plus and still get the error when I try to toggle to GT3 steering
that's what I meant;
having Power steering plus = GT3 calibration is showing as an option (albeit with error message)
but when power steering plus is not equipped = no option for GT3 calibration to start with.
My PIWIS2 arrived last night. I followed the instructions set out by nhnguy12 and it worked. On my piwis 2 I did have 918 GT3 and TOP options that my mechanic did not see when he used his piwis 3. So maybe the coding device does really matter. I did get the error once I changed the setting on the eps. But I coded the errors out per the instructions. I only had a chance to drive it a few miles but it immediately felt different and better.
Yah I have the piwis II and had the same experience, except I didn't code out the error code nor did I drive it. Would be curious your feedback over time.
Interesting, I guess PIWIS 3 can work too. My mechanic said he saw it on a very similar car to mine (both built in may 2013). He also took my car in but gave it back because he didn't see the feature. Well now that I have my own I activated the PTV feature as well that nhnguy12 discovered as well. No issues with warnings or anything and the brake diff seems to still be functioning on acceleration (base carrera have open diff). I went to a empty parking lot and I went around a corner but make sure to stay on the gas. I think it did understeer less but between the rain and the different GT3 steering feel it was really hard to say.

How did you find the steering feel in the rain? We don't have too much of that here in Arizona.

I felt many of the same things you experienced in your writeup. After 20k miles I grew to hate the feeling of the old rack. It gave the initial impression of feel but I soon realized it never changed, not with the road conditions, not much with the tires, and not much when I loaded the car up. I never quite got used to the heavy feeling immediately off center but then zero load up as you pressed on. I also disliked how heavy it was on the highway near center. I always thought this was weird because a 911 should be so light up front I couldn't understand where the weight off center came from. In my experience with old bmws from a beat up 200k mile e46 to a e90 m3 and their lovely hydraulic racks I could steer these cars around the highway with just my fingers and change lanes with my palms yet I could almost take corners with my eyes closed because once you had even only lateral load on the front axle it would load up and communicate exactly how much you were using the tires. The original 991 steering rack was artificially heavy and hard to steer but didn't build up which gave me a feeling of almost guessing every time I went around a corner. Even in the rain (where the old one was the worst) and around parking lots not only is it much easier to steer I find I just turn the wheel, feel the resistance build, and know exactly where I am pointing the wheels. I tried a 992 gt3 at pecla and it was amazing. While it doesn't feel exactly the same as the 992 gt3 they are somewhat similar in the way the force does build up with front axle load. I highly recommend this to every 991 and 981 owner. I would even go as far to say now that it is discovered and it is this easy to do, I think it is required. I honestly cannot go back.

Thanks for the insight! Curious to see how the updated calibration stacks up against the holy grail 997/987 steering racks. Might rent a 987 one day to try it out.
Edit: I wonder if your indy shop would be willing to drive your car and their 991 (the one that didn't throw a warning) back to back. That would answer whether the warning thrown by some EPS modules actually impacts how the calibration performs.

I guess it doesn't hurt to try this in my car. I'll try it this weekend and do a canyon run if I have time and report back!
So I just went ahead to give this a go. First thing it deactivated power steering plus so around parking lot speeds it’s def more effort to steer and overall at city speeds there is an increased in effort. Not sure if I like it better or not or maybe I am just not used to it. I will give it a week to get more wide driving experiences. I do feel like the wheel moves more with the road surfaces than before. But the power assist is very much lowered. I’ll see how it goes this week and report back

Are you close to Angeles Crest? That would be a good way to evaluate the changes.

That's super interesting. I didn't have Power Steering Plus and I immediately noticed it was lighter at neighborhood speeds. nhnguy12 had a cayman S with Power Steering Plus and said it was lighter as well. Could it be the 991 Power Steering Plus is even lighter than the 991 gt3 calibration but not the 991 base and 981 with Power Steering Plus? I am curious to hear what happens to the steering weight when you push the car abit more.
