^^ +1 ^^

I think that when it was stated that the EPS hardware was identical, that just means that the specific part is the same (steering column, steering motor??). The GT3 has a bunch of differences in the entire suspension set up, so as much as I'd like it to be the case, I don't think the GT3 steering calibration will translate to a regular Carrera. Not that it was bad to begin with IMO.

Ah, so inconsistent writing is what's throwing you.

USA site:

"Electromechanical power steering with variable steering ratio and steering impulse "

And if you add Power Steering Plus the speed sensitive bit, too.

 

This is typical of many product marketing spiels.

Even though all the various models in a product line have all the same base features, the marketer will describe them differently or highlight more of the same specs in the upper model so that you think you are getting a lot more than the lesser model.

In pyramids quote from the UK site, this is classic deception!

 

Seems like it is

 

Don't forget the electronic F1 inspired diff!

 

I am sorry to ask this stupid question which may already be many answers out there. How do you change the setting?

 

Tire pressure gauge with a bleeder valve. The air comes right out.

 

Keep flipping through the menus on the screen within the gauge cluster (the one to the right of the Rev counter) until you get to the tire pressure menu. Go further into that menu by pressing the select button / pushing the stalk forward (depending on if you have SD or Multi Function steering wheel), then select comfort pressure setting. Going to fill info screen within that menu shows you how far off you are from the intended setting. For example, if it says +2 in all 4 corners, then you have 2psi too much in all 4 corners.

Really recommend doing this.

Hope that helps.

 

Looking for some clarity - is in fact the Power Steering Plus $270 option on my 2013 Carrera S the same as the GT3's "Electromechanical power steering with variable steering ratio and speed-sensitive power steering assistance" ?

 

I just order a set of KW V3 Coilovers, I think it should help bring some steering feel back, from all the feedback I read online with just lowering the car with H&R springs. With a completely new suspension it should help transform the handling quite a bit, will give feedback after installation

 

That is what I would like to know. Is it better to order the Power Steering Plus option just in case it is the one similar to GT3 steering just with different software programming?

 

Power Steering Plus provides additional boost on the Carrera models only at low speeds for parking. This feature isn't available on the 991 GT3. PSP isn't related to the speed sensitive steering on the GT3 which is designed to provide the best steering feel and response at all speeds.

BTW the Carrera models also have electromechanical variable ratio power steering and I always thought it was speed sensitive as well.

The steering unit itself in the Carrera and GT3 is the same except for the software programming. But some of the difference in steering feel is due to the wider track and different tires, springs and shocks, lower control arms, and suspension settings of the GT3. That's why I don't think the GT3 steering software would work properly on the Carrera; it would have to be recalibrated for the differences of the Carrera chassis.

 

But would it work on the Anniversary model because it is a widebody and rear wheel drive?

 

Supposedly, nearly every suspension piece on the GT3 is revised from the Carrera so despite the Anniversary car having the same wide track chassis there are still many differences. I'm sure the steering software on the GT3 is also programmed to work with rear wheel steering on the GT3 which the Carreras don't have.

Not saying I know it wouldn't work, just that there are reasons why it might not.
