GTS 4.0

[JurassicGTS]

So I just picked up my car from the guys that I got to fit the Car Graphic controller - they had the car for 2 days in the end and I had a chat with the installer who had to spend a little more time fitting the unit than he'd expected so I thought I would post what I found out, and first drive experience.

The controller I received was the latest Car Graphic that controls the valves via the SE button in the cabin and does away with the external remote - all good so far although I must admit, when I ordered a controller from Scuderia, I didn't realise this was the version they would source and send.

The first issue I had was that although Scuderia are an official UK importer, they had to import from Germany via special order - that ended up taking a month to arrive via a courier who then immediately sent it back to Germany because the import tax hadn't been paid ! In the end, it took 2 months to actually get the part - thank Brexit for that

Onto the install - from speaking to the installer this evening, he told me that when he started to look at the kit and the instructions that are on the Car Graphic website and which you have to download (none are sent with the kit), he quickly realised that the wiring is set up for left hand drive cars. This meant that he had to make a couple of extra wiring extensions so that he could locate the part where it is supposed to go (in a recess under the passenger seat carpet) and still reach the inputs it was designed for. Once he'd worked that out and made up the wiring, he said the install was relatively straightforward.

I am going to check with the importer to see if there are options for RH and LH cars as this will obviously catch people out like me.....

Onto the driving experience - a quick blast around the lanes tonight with the roof down, and in all driving modes, revealed a lovely deep throaty exhaust note that builds all the way through the rev range.

It's very addictive and obviously I can switch the SE off and the car returns to normal.

I can see where the comment about increased drone comes from - the exhaust note at a steady and constant speed is certainly apparent, but then I wouldn't have the valves open when sitting on the motorway anyway and would just turn it off.

Hope this is helpful to anyone interested in installing this bit of kit.

if you do decide to get one and you’re in Essex area and want someone to fit it for you, then ask for John at Porsche Specialist Services - he’s an expert now

Does it revert to absolutely bog standard when you turn it off, I.e. valves fully closed at motorway speeds?

My understanding when you had the separate remote was that it was either valves fully open with button 1 or standard set up with button 2, maybe the other way round.

Then with the standard set up you could have normal sports exhaust mode or standard exhaust mode using the cars PSE button, therefore giving you 3 options?

Am I correct with this assumption?

From the CARGRAPHIC blurb

Exhaust valve control unit - how it works: The CARGRAPHIC valve control unit is installed between the exhaust valves and the factory control unit. The CARGRAPHIC valve control is activated by a combination of buttons in the interior. Subsequently, the 2 operation modes are selected by the PSE / tailpipe button in the center console:

[ul][*]SPORT mode: valves always open[*]COMFORT mode: valves always closed (security open at 4000 rpm)[/ul]The last selected mode is saved even after the engine is switched off and is executed when the engine is started again.

Thanks,

What is confusing me then is, with the system that has the external remote, what then does the PSE button do if everything is controlled by the remote?

The button on my remote overrides the cars PSE button. So when button 1 is pressed valves are always keep open regardless whether the PSE is on or off.

When button 2 is pressed car reverts back to factory PSE settings.

hope this helps

Brilliant, thanks Glenn.

You then actually have 3 settings, so for me the remote is probably the better option.

That is exactly how my CarGraphic system with 2 button remote works too. There was no need for any additional wiring either. And if anyone tells you that the GTS 4.0 engine is too quiet, mine failed noise testing at Croft trackday on Thursday - 110dB at 5,000rpm with the exhaust valves open! Ok with valves closed fortunately but perhaps a warning to those who go for the cheap option to jimmy the valves open all the time that they might well fail noise testing.

I've got the remote fob with 2 buttons as well, supplied & fitted last month by RPM Technik in Tring. It took just over an hour to do (as they fit so many) and I nosed around their great collection of cars (inc. quite a few GT3s, GT4s & Sypders) whilst waiting. There's a really good 'greasy spoon' cafe in the industrial estate too that kills off 20-30 mins of waiting time too. I'm still playing with the exhaust settings - it does sound quite raw with the valves fully open, but I'm getting to like it more and more when I'm in the mood for more noise.

Slight change of subject, the rear spoiler on my car is not raising has high as it should. I thought it was low when washing it I could only just get my fingers under to clean it.

After looking at another 718 I would guess mine is only opening halfway.

Does any body know of a secret setting to limit the height, or do I need to take in to OPC

Have been right through the manual and settings in the car to no avail

 

[Scrounger]

Did you keep your finger on the button until the rear wing stopped? Just pushing it once will only lift it a small amount. There is a guide on adjusting the rear wing on another forum if you need it. It's relatively simple to do, just time consuming.

A quick look at the internet indicates that it is not an uncommon problem.

Variations on 'press and hold' the manual button seem to be the only alternatives to a visit to the dealer?

 

[glenn duval]

Thanks both, looks like a trip to the dealers

 

[glenn duval]

Before going to the dealers in decided to do a it more digging.

A friend of mine sent me a picture of is Bosxster 25 which is the same. So looking on the net seems Boxsters only rise about half as much as on a Cayman. and completely different to 981 cars which I why i thought I had a problem.

I'm certainly not trying to be picky or criticise anyone here, just genuinely trying to understand.....

As I understand it the PSE button opens the exhaust valves when pressed at engine start, but the engine management system will automatically shuts them down again between around 1400rpm to 3800rpm when they open again. Understand this was done by Porsche to resolve a drone issue. It seems all these aftermarket options do is enable the valves to stay open between 1400 and 3800 or am I missing something fundamental?

That is my understanding. Droning is really only an issue at motorway cruising speed which is when you would revert to valves closed.

You’re correct - what I’ve ended up having had fitted is a system that allows me to control the valves to my liking via the PSE button. Most of the other owners on here have the same functionality, just via an additional remote.

I‘ve managed to get out in the car for a few longer runs over the past few days and have pretty much had the PSE button pressed the whole time and valves open - at a constant 70 there’s a rumble, but it wasn’t annoying. might different with the roof up but I didn’t find it annoying.

Pushing it round the lanes in S or S+, with the added soundtrack, is just epic…

Apols to anyone also on BoXa.net for the repeat post in here. Wonder if anyone has recent experience with lead time from their freeze date to delivery?

We finalised our Boxster GTS spec in the third week of May and collecting tomorrow.

Congratulations- looks amazing. great contrasting interior choice

 

[JurassicGTS]

@David_JS, David, did you get any further information from your SE?

Comclusion elsewhere was that factory shutdown was the most likely issue to be impacting this.
