Update: I installed my PC this morning. It really works as advertised. The throttle response is much better and my Macan now drives like a Porsche. I tried many different settings. For now I'm in City +3 and it seems quite good. Glad I bought it. 👍
I'm in City +3 as well on my Turbo.

Your performance vehicle now responds and feels like one and not a 4 cylinder KIA mouse motor.
Don't knock it till you've tried it. I know the stereotypical Kia bashing but we have a 4-cylinder Kia Soul we use as a winter beater. It has amazing, near instantaneous gas pedal feel. So much so that it takes some practice to NOT spin the front wheels when exiting a turn in the wet, especially on a hill. It has a measly 167hp. To say I'm surprised by its driving response would be an understatement.

I'm hoping the roar pedal gives me a pedal feel in my GTS which is even half as responsive as the Kia.

I know how ridiculous that sounds, but the point is direct drive by wire feel does exist out there, from the factory. Just not in a Macan.

The SB made me realize that the lack of excitement or dynamism I felt when initially driving a Macan was due to the throttle. The handling was great, but something felt missing (and I thought it was perhaps due to the different feel of AS which I had never experienced). Yes, when I bashed the pedal it did move and it is fine and I would still be a happy owner without the device. It is really a preference.

Yeah, no offense to your KIA, kinda meant the "beater" Asian stuff in general. To me its all the same cheap junk. Well known that the lower powered stuff has a ramped up pedal that gives you the illusion of more balls than the car actually has. KIA Soul, probably would be a good beater.

FYI: For anyone interested in Roar Pedal, they have offered a small discount code of $10 (better than nothing I guess).

I think im going to go for the Roar Pedal because of the fact there is no controller or unit that I have to mount under the steering wheel or anywhere for that matter! I love how there are no visible wires & it operates directly from your phone.
It also happens to be the least expensive which isnt bad either.
$235 CAD or $169 USD (minus 10$ with discount code PORSCHE)


I will report back once my GTS arrives in about 30 days and I get a chance to get this puppy installed.
Only drawback I see is, if the app doesn't work or gets weird in the middle of a drive!

You call it a problem, I get it it, but is it an intentional problem by Porsche Engineers for us Americans so we don't kill anyone on local city streets or a limitation of the engine??

It's intentional and not a limitation of the engine. Many believe it's for fuel economy, but I doubt it. As you suggested I think it's most likely to reduce the likelihood of an inexperienced driver launching the car into pedestrians when trying to park for example. The Macan has a very wide demographic of potential drivers and unfortunately Porsche have to account for the lowest common denominator.
A throttle that is docile for the first inch or so of travel gives someone time to react if they press it instead of the brake which seems to happen more often than you'd think...

The stock pedal vs throttle relationship would look like an exponential curve, and the pedal commander takes the pedal signal, applies a curve that resembles an inverse exponential resulting in a more linear relationship between pedal and throttle (like you would get from a typical mechanical linkage)

Rectangle Slope Plot Font Line


So, say the Macan throttle curve is blue, PC applies the red curve, result is the dashed line.

Not important, but some might find interesting:

With modern cars (particularly turbocharged) the pedal position doesn't directly relate to throttle position but is a "torque request". The ECU will use a combination of throttle position, ignition timing, cam timing, boost pressure etc. to provide a torque output relative to the accelerator pedal.

^^^^^^^Very cerebral appraisal. Agree with the safety explanation vs fuel conservation. The Macan does indeed appeal to a broad range of owners many who have never owned nor experienced a relatively high performance vehicle that would accelerate quite rapidly if the throtle inputs were not mediated in some fashion.
Your explanation has far more merit than any others I have read so far on this and other forums.

Just installed the Roar Pedal. Took about a half hour including the 15 minutes wait for the car to go back to sleep before disconnecting the pedal wires.

Super easy to do. Like people said. One bolt to free the pedal itself then unplug it and plug the RP connectors in.

Used a 6" long T30 bit on a micro wrench to get to the bolt.

Most time consuming bit was getting everything back in. I tucked the RP itself into the plastic trim of the dash on the right.

Went for a quick drive to make sure everything was OK. Tested a few settings. Super happy with what it does. I settled on Sport 3. Makes Normal mode actually drivable. Petfect for my wife.
I tested Race 9 for a laugh. It's amazingly fast.

I'm very very happy with this modification.

Whoa whoa!! Any chance you can reply here,and dive a bit deeper w/ your thoughts once you get another 1-2 days under your belt w/ the RP? Im super super curious of what you think of the stock GTS VS w/ the RP. I know you were on the fence about this and im really happy you went for it... Im super super eager to hear what you think! Im ordering mine tomorrow, but truthfully, I want to drive my GTS stock for at least a week to get the feel of a stock GTS under normal conditions...and THEN install the RP. Since you already have that experience.... please enlighten us a lil deeper whenever you can

You bet, so far the best way to describe it is simply that the car responds to every bit of throttle input you give it, which is just how it ought to have come from the factory.

Using RP "Sport 3" with the car's factory "Normal" is more responsive than the Macan's factory "Sport+" throttle wise. The shift points are still the same "normal" as they were before so it shifts up pretty early still, but it's very drivable now, unlike how it was from factory. It was so lazy it was undrivable, in my mind.
I've exclusively driven my 2400kms so far in sport+ because it allows me to modulate the rev range better which is crucial during break in. Even in this mode there's a significant delay and then a slow non linear feel to the pedal input. Now with the RP in S3, that delay is simply gone. Now when I blip the throttle there is a corresponding acceleration surge. It's very linear and reminds me of the cable throttle, naturally aspirated cars I had before, rather than the turbo cars I've been driving for the last 6 years. I'll play around with the RP "Sport" settings and figure out my sweet spot, but so far Sport3 feels pretty good. S2 was still ever so slightly lazy. I'll test the RP "sport+" settngs too.

I then tested Race and cranked it up to 9 to see just how wild it is. I can see myself losing my driving license and the car getting impounded in this mode. It reminded me of the blown e92 M3 my buddy built. It's almost instantaneous WOT. I had a grin on my face the whole time. It's possibly too sensitive for rush hour stop go traffic, but I can 100% see myself using this mode for a blast every now and then.

I'll be driving into the city on Tuesday so I'll run it through its paces then and will report back.

I absolutely recommend you drive the car as is first for a while anyway before installing the RP. I honestly feel like I've got myself a brand new car, truly.

seems to be a diverse topic, only having the car a month still on fence, I do have a similar product on my NC1 which also has multiple settings normal and sport 1-7, it does make a diff in pedal feel and find myself leaving it off most of the time. one of the reasons on the fence is ease of install, both require twisting under the footwell, but Porsche requires access to screw (is it difficult) NC1 had a push plug no tools required.. will continue to watch and read all pros and cons, car only has 900 miles so plenty of time to decide..meantime enjoying it immensely as compared to previous daily driver
