+1. Night and day difference.

 

Not sure about tune but SC does increase the torque and rev for me. Also, PCCB, *** and SC with same mileage and price, and you still debating which one to get? IMO there is no debate which one to buy.

 

I hear 'ya. I probably don't want to know what I'm missing!

I'm happy with it the way it is, at least for now.

 

+1 agree that the flash is worth it, in fact is one of the main reasons I'm sticking with the 911 turbo range for my new car, and not going with a new M4, F-Type etc. A tuned 996/7 turbo is just more fun to drive even though its an older car.

As an aside, spent the morning test driving the new Macan for my wife (and comparing it to the X4 and GLA45 AMG), looks like we are going to have 2 Porsche garage! The Macan drives very well for its size and is well appointed with lots of the 991 parts so is good value (in Australia). Will be getting the diesel as my wife feels it has more power than the petrol due to the large amount of mid range torque, even through the petrol is faster on paper. So the Macan will be the comfort car with all the modern bits (eg. integrated Bluetooth) which will be the garage complement to the older and more raw 997TT.

And I just saw that the 997TT with PCCB/SC is now off the market..... The hunt continues.

 

+1 I avoided PCCB cars, the rotors last forever but if you manage to damage them shifting tires or doing other work on your car...ooops 20k gone.

 

They do look cool PCCB, SC is a must.

 

So basically as I plan to add a flash tune and use the new DSC solution for active suspension, the end result will be far superior (power & driveability) that the original SC? And both these additions would override the SC settings anyway?


If that is the case, then I don't need to buy a car with SC.

 

For the record....and to clarify something on this thread....Sport Chrono and a Tune are NOT mutually exclusive items as the discussion seems to indicate.

Most good tuners, will tune the global settings and tables such that you still have different performance with SC on and with it off. So after a tune, you will have more power in both, but with SC on you will have even more than with it off (or at least more TQ...and other variables considered).

Many have suggested , and I agree, if you see a SC car, I would get that over a non SC cars as many others would. When looking you will find most have SC included and will be a selling point if/when you are ready to sell.

Also a tune does not adjust all of the settings that are changed with the SC option (Such as the suspension, etc.)....The tunes optimize the settings and variables within the engine controls..

Sports Chrono Package Turbo option
The available Sports Chrono Package Turbo provides the choice of an even more sporting set-up of various vehicle functions, including engine and Tiptronic S management, and profiles of the Porsche Stability Management (PSM), Porsche Active Suspension Management (PASM) and Porsche Traction Management (PTM). The option also brings overboost.
By hitting the Sport button on the center console, the driver engages overboost. This briefly increases turbocharger pressure when accelerating under full throttle. An arrow in the turbocharger boost display informs the driver that the car is in overboost. This additional boost of turbocharger pressure is achieved by adjusting the turbocharger blades to increase maximum turbocharger pressure by approximately 2.9 psi (0.2 bar), in the engine speed range of 2100 to 4000 rpm. The extra high level of turbo boost lasts for about ten seconds allowing the driver to confidently execute a fast maneuver.

Good luck with your decision and purchase OP...

Clarifying question - does a car without SC not have a sport button?


I see from another thread that the SC also adjusts the PSM (less obtrusive) and more power bias to the rear wheels - both attractive options.


Regarding how a ECU tune works with SC and without - I would have thought that the ECU tune on a car without SC would be the same as maximum performance (sport on) on a SC fitted car? So there wouldn't be any performance difference to a car with SC and an ECU tune, compared to a car without SC and an ECU tune.


For the suspension, I assume that if I get the aftermarket DSC module then the SC adjustments to the suspension won't be as good as the DSC changes, and overwritten by the DSC anyway.


From another thread
https://www.6speedonline.com/forums/...oes-sc-do.html it mentions SC also adds the following:
Some other functions that you get with SC are the ability to set and store personal settings, such as daytime driving lights, the "Welcome home" function, air conditioning, activation of the rain sensor and door locking

Although the main changes available with SC (more boost and suspension setting changes) aren't relevant if the car has an ECU tune and DSC, there are enough smaller changes (rear wheel bias, PSM and personal settings saving) to make a car fitted with SC still desirable.


Have I got this right? Sorry for all the questions, but I'm not familiar with the 997TT and have only test driven one car (with SC).

 

The only reason to even consider a turbo without sc is because it is SIGNIFICANTLY cheaper than a car similarly equipped.

Although it is not apples to apples, look up a 6speed member Gary Chios (or something close). He bought a .2 tt without sport chrono and has had a lot of headaches trying to replicate all the sc functions.

Plus as TheRock pointed out, when it comes time to sell, the SCoptin will make the car much more appealing as it is widely seen as one of the "must have" options.

 

Guys,


Still trying to make up my mind between a car with chrono and without (the without has a nice exhaust & guards red which I prefer) and I want to confirm one thing about SC. The 997TT brochure is clear that SC provides personal settings as outlined in post #24.


However I can't believe that a car without SC (which is all about 'sports' / track driving) won't have personal settings - doesn't make sense as the personal settings are more about comfort and should be standard on a car like this, not provided through a sports pack like SC. I did drive the car without SC during the week but forgot to check for these things.


Can someone confirm that a car without SC doesn't have personal presets? Thanks!

 

On my 2012 GTS without SC there are a few (DRL for one) things that I can set using the OBC and the stalk on the left side of the steering wheel. But without SC there is no personal setting functionality in the PCM - e.g., I cannot set things like door locking or fade out on interior lights, etc. Without SC personal setting are still available but the dealer has to set them for you.

As I said I don't have SC but with a manual transmission I'm not missing much if anything. With a PDK I think SC is a must have.

 

Thanks jhbrennan,


Does seem very strange on an expensive car like this that these settings will need a trip to the dealer to change. Trying to understand these better, I assume SC does the following:
- Able to set or cancel parking lights on during daylight
- Aircon, unsure what personal setting that would be?
- Welcome Home varies the length of time the fog/tail lights stay on when locking / unlocking. Not a major feature IMO.
- Activation of rain sensor. I assume (guess) rain sensor is standard, and SC settings adjusts the threshold of activation when rain is detected??
- Door locking. I assume this setting is to automatically lock the doors when you start driving??


The important personal settings for me will be the seat position and the mirrors which my 996TT has stored based on what key is used (my key or my wife) which I assume is still available in the 997TT as it is not listed as a SC personal setting.


Given all the things that SC does, I wonder why anyone would buy a new car without the SC option especially as it isn't that expensive.

 

Dean, I understand the beauty of Guards Red but given the conditions, IMHO the choice is OVERWHELMINGLY so for the car with SC, PCCB, and Sports Adaptive seat. It's not even remotely close to me, and it's not because of SC option either. It's the other 2!

1. For one in your life, has PCCB brake. Take this car before someone else jumps on it. PCCB is a life changing event :-) and I consider it one of the most important and fun options of our Turbo. Same stopping distance as Big Red but 35 lbs lighter of unsprung weight and hence improves both ride and handling, and initial bite similar to being stopped by the hands of God. Last 100,000 miles plus. Only time I don't recommend it is for the track (for reasons best left for another discussion).

2. Sports Adaptive Seat is the most comfortable seat many of us have ever used. Don't go without it.

3. SC is controversial with respect to ECU tune - I don't feel strongly one way or another with this aspect of SC, but there is no controversy about the OTHER things that it does. You know that it does a few other things right? I'll find my post and re-post it here if you don't.

 

Thanks Can,


My 996TT is Guards Red - the best color for a 911 in my opinion, however it seems all the cars for sale in Australia are black or grey, all with black interiors which makes the cabin very dark.


So I'm having trouble rationalising the big $$ trade up to a 997TT (in Australia these cars are more than 2x what these sell for in US) when I prefer what I have now, red with tan interior, and don't want to make the change and regret it later.


I do think the 997TT is the better car mechanically, my 996TT is a tip and I definitely want a manual, and the big change I noticed with the 997TT is the better suspension (I have a flash on my 996TT so power is about the same).


I suppose everyone buying these cars second hand goes through similar thoughts. Unfortunately the car with SC, PCCB and adaptive seats has sold, should have jumped on it. Guess I'll just have to wait it out, there are only typically 4 - 6 manuals on the market at any time here in Australia.
