I’ll let him clarify.

Guys, I'm not saying that changing the coding/software on a C2S will change the vehicle to a GT3. That's comical. And I'm not trying to swap GT3 suspension parts into a C2S either. All I wanted to do is mirror the coding for the electronic steering from a GT3 to a C2S, which I have accomplished by disabling Power Steering Plus because that is how a GT3 comes from factory.
And NEVER did I state that this will provide you the same driving characteristics or performance of a GT3. All this does is give you a stiffer/heavier steering feel at lower speeds (< 50MPH) which is how the GT3's steering feels. That's all!!

Please keep us posted. A “heavier” less assisted feeling would be a plus.
Not sure why you’re associating power steering plus with it?? That’s optional “add on” software that isn’t standard on any 991. Not even an option on the GT3.
Some clarification?
Thanks

What I did was mirror the coding from a 991.1 GT3 in the steering section of Vehicle Data with my PIWIS onto the C2S. And yes, I can confirm the steering wheel is much stiffer. All I wanted.

Nice. Quick question, did you have the power steering plus option on the C2S?
Trying to take that variable into consideration, as it would be good to compare a non power steering plus Carrera after the GT3 coding.
There is a significant difference in cars that do/don’t have the PSP option.

There is a huge difference in steering feel on Carreras that do and don’t have the PSP option.

What I WAS able to do was disable PSP then go to electric power steering module and do automatic coding adaptation which I think updated the steering software to the 991.2 settings. Overall the feel at all speeds is improved with more road feel than before.
I also experimented with decoding power steering completely, which the steering then became very heavy at all speeds with absolutely no feedback at all, not good, so returned that back to standard INSTALLED.
Let's clarify this because there are some improvements to be gained with the coding process and an alignment to GT3 spec, which I've done on my 991.1 C2S - there is certainly more wriggling of the wheel and sensitivity to road feels but it's still nothing like my 997 turbo, although it is not bad at all, just different and more anesthetic.

If anyone in the Bay Area with access to a PIWIS wants to help play around with this, happy to bring my .1S when the SIP is all over to experiment and try.

I am actually thinking of just buying one of the Chinese clones. I should have ordered one when I paid the dealer to program out my spoiler for my duckbill retrofit. Ill let you know if I get one.

Hey Joe, great to see you're still modding away! Iwrenchmy911 - love Orinda, let's arrange a time to check out the PIWIS once things are calmer... hoping this works as others have reported. Would love GT3 steering feel via software. Have you tried on your car?

Sure, just shoot me a PM or email iwrenchmy911@protonmail.com when you want to arrange a meetup. Yes I've done it to my car as I described I tried a couple of methods. I don't think it's like a GT3 now with just the steering software update. Other things we can do:
- Aero programming of rear spoiler i/e adjust the deflect angle so that it doesn't act like an air brake and adopts the settings for cars with aero kit and deploys at a lower angle.
- PDK calibration
- Comfort entry enable (although I'd need to poke around and find where this is set, it's not a setting I care much about so don't have it memorized)
- maintenance interval resets, oil change fill mode (I'll do an oil change for you for 70$ you bring the supplies and the Cokes)
