991.1 GT3 steering software onto 991.1 C2S?
#17
smuggness of some of your own comments
on HFS threads? Where have you been?
Who died and made you Queen of this
subject & the ultimate authority as to
LECTURE Rennlisters as to what a good
deal? Give me break!
sometimes & read back what
your write & how smug you
sound?
you are making to the gt3 forum,
George? Please! Get a hold of
yourself.
doing? Showing off to the forum
crowd by switching from a .1 991
gt3 to a .2 991S coupe?
perhaps like you. You are too clever
& found me out! You have exposed
that 'the king has no clothes'.
constantly posting here on Rennlist. Maybe
it be better investment to spend more time
with your family/work & less with Rennlist.
I personally love Rennlist & all the folks I have
been fortunate to meet via this great forum.
And people want to meet me because I have
helped them with their custom orders & PTS.
I have nearly 1500 pm's which I have received
& answered. And countless emails & even
telephone calls overseas! People appreciate
when someone makes an effort & tries to
help them out.
So before making wise *** comments like
"Who gives a *uck what hood I'm in today",
keep it bottled up if you don't know why the
other person writes something. Just because
you don't understand, or condone it, it doesn't
mean its not important or meaningful to the
person posting it. And that there might be
a reason for it that your great mind can't
figure out. Again, that smugness needs
to stop!

Even if the software is identical, and the actual steering hardware is identical as well, the geometry of the car (suspension, bearings, etc.) and not to mention the different tires, would probably contribute just as much to steering "feel" as the actual software and hardware would.

Oh no. Watch your back. Eduardo might unleash on you. You mean you can't turn a 991.2 "turbo" into a NA GT3 with just software and a "chip tune"?

Wearing my steel pot and flak jacket, head and butt down.
I am totally ignorant as to how the steering feels in the 991.1 GT3, because I have never driven one. I have heard others say that the GT3 has the best steering feel of all the 991.1 cars.
With the above in mind, the one time I drove a 991.2 (base Cab), and I forgot to look to see if it had PSP, but I did not notice the steering get lighter when I drove it through the dealer's parking lot. However, having a 991.1 GTS to compare to the base 991.2, I really sensed that the steering feel was slightly better than my 991.1 GTS.
Some months after I drove the base 991.2 I made some changes to the suspension set-up on my 991.1 GTS, as follows: DSC PASM module, replacing OEM. Car has PASM, not SPASM. TPC front and rear adjustable stabilizer bars, set to TPC's recommended initial stiffness. Moved the negative camber on the front to the max available on the OEM GTS suspension, as I recall, about 1.17 degrees negative. Rear was slightly adjusted to stay in the correct relationship with the front.
There is no way the suspension on a GTS can directly compare with that on a GT3, but I will say that I believe my 991.1 GTS transfers enough better feel through the steering to make me happier than I was. Response and turn in are very much better. Much better handling on the few times I've taken this car to a track since making the changes.
Unfortunately, I will need to drive my 991.1 back to back with a regular 991.2 to be in a position to compare the steering now that I've made these changes. I do know generally what I like and do not like, but that's about the extent of my expertise.
Maybe, even without software changes to the 991.2S, a little more negative camber at the front could help. I just don't know, and then there is the consideration of rear wheel steering. I have more than enough trouble trying to figure out how to use my damn cane to keep from falling over like the guy on the end of the bench on Laugh-In.

Wow, so many experts on here that make my head hurt...especially the ones that own neither car lol
Subscribed for the software change here also! Please share if you know something.
kwikit356, the below is what my shop quoted me after driving the '15 GT3 and immediately want to do something about my .2 C2 steering feel and handling.
- Install front GT3 lower control arms and adjustable front & rear
anti-roll bars.
Front adjustable anti-roll bar, 3 position
Rear adjustable anti-roll bar, 5 position
Front GT3 control arm set, rubber bushings
4-Wheel Alignment
Install lowering springs and wheel spacers.
Lowering spring kit
- 0.8" front, 0.5" rear.
- Kit also available to lower front 1.2" and rear 1.0"
Spacer 7mm Alu Anodized W/ Bolts
Spacer 15mm Alu Anodized W/ Bolts
The shop was impacted by Harvey. As soon as backup, will have mine done.

WOW! this thread escalated rather quickly! haha
Anyway, I've figured out that the "GT3 Steering software" is, in fact, just removing the "PSP" function off with a PIWIS tester and then re-coding all of the control modules for the new change.
Hope this helps others!!

What Brian is alluding to is the possibility that the software is actually the same and all of the feel differences are due to the actual suspension setup being different? I could see this...

PSP (power steering plus) is an option that is on less than half all 991’s.
