Snake oil or not?? Sprint Booster
#46
It is subjectively better for some that prefer more acceleration with less application of pedal. I can understand this is more comfortable for some, and I respect that.
Objectively, it is not "better" if we are talking performance because unless you are sure it is more linear + has the same distance for max acceleration applied (thus same ability to modulate throttle on track/rain/grip threshold high performance situations), then it does not provide an "objective" advantage over stock.
In fact, if it is LESS linear like the one I experienced on a BMW, it is a performance detractor, objectively, for limiting the ability to modulate throttle.

And again for the 1,000th time, you can put it back into stock mapping with a finger press if you don't like it on the track (but you will).

I am reminded of the salesman who in 2006 claimed that Sport added 'about 30 horsepower' It of course does not and I went elsewhere rather than deal with someone blowing smoke out of his a$$.

"Sport Chrono Package
In conjunction with the optional Sport Chrono Package, PSM is supplemented by a ‘Sport’ mode. It allows a significantly more sporty driving style, with PSM remaining active in the background. For a further enhancement to your driving experience."

"More than a collection of the world’s most refined race-bred technologies, the Porsche 911 is a driving experience. The new Sport Chrono Package Plus option is an all-new integrated system providing simultaneous enhancement for engine, chassis and the optional Tiptronic S transmission. The results are even greater performance and pleasure from your Porsche.
Pressing the “Sport” button on the center console is all that’s required to begin exploiting the new 911’s generous reserves of power and agility in a more immediate manner. In Sport mode, the engine management system’s variable parameters are recalibrated to enhance engine response. A modified throttle map empowers your right foot with more progressive reaction to each tap of the accelerator. In higher gears, a rev-limiter works in tandem to offer additional protection for the engine under acceleration.
On vehicles with Tiptronic S transmission, automatic gearshifts also become faster and more dynamic. Lift off the throttle – even at high revs – and the system immediately shifts down to apply engine braking.
Unwanted upshifts in manual mode are also prevented, even as you approach the engine’s rev limit. The payoff? More secure and predictable handling, particularly in the corners.
While all of this is happening, PASM switches to a more rigid setup with firmer electronic damper settings for precise cornering, improved high-speed stability and tenacious road-holding traction. (Note: PASM, or Porsche Active Suspension Management, is optional on the 911 Carrera and standard on the 911 Carrera S).
Porsche Stability Management is also performance-optimized by raising the thresholds for triggering automatic intervention by the ABS and engine management systems, resulting in a more natural response, but less forgiving to lateral and longitudinal g-forces.
A digital/analog timer mounted on the center dashboard keeps score, measuring time as deftly as the 911 concept transcends it.
To help you gauge your 911’s performance in a more exacting manner, a digital/analog stopwatch tracks time from hours down to hundredths of a second. Driving times can be recorded for any stretch of road, and benchmark times can be defined.
Stopwatch functions are operated using a control stalk mounted to the side of the steering wheel, and data is continuously fed to an on-board computer integrated into the Porsche Communication Management (PCM) system.
A second digital display located on the instrument cluster gives your eyes another option for viewing time information, while the PCM display lets you analyze detailed performance data at your leisure. The system records and displays the time and distance traveled on the current segment, number of segments completed with respective times and the fastest segment. Other useful features include a memory function controlled via the PCM system which can store a range of personal preferences."

Says SC affects both PSM threshold, and engine maps. However, does not affect power at all.
Interesting. I have SC but haven't retrofitted yet. Maybe I will.

Snake oil to me = no true objective performance gain, when it is claimed (such as with this product).
So, to me it is snake oil. I'd spend the $300 on something else. Like a tire.
Sport Chrono has a few changes to PSM/Engine mapping for responsiveness, so perhaps that is an objective improvement. In-fact, $300 is the cost porsche dealer in Austin quoted me to install my SC.
#54
Using Sport on an E46M3 I found myself flooring it in 3rd to use the remaining throttle to merge into a lane of traffic. Problem was there was no further acceleration available in that gear, just a lot of unused foot movement. Embarrassingly non linear and a bit scary. Never used it again.
There is a case for a Porsche map that is better, more lively, than stock but not as aggressive as the Sport setting. I found that the settings of my Ecu mod were a great compromise and did indeed make the driving experience more fun. Haven't touched Sport since. Surely no should need both an Ecu mod and this add on patch.

Fair enough. More fun is certainly subjective.

Here's the 997 Sport Chrono kit at Suncoast....
http://suncoastparts.com/product/9X7SM.html
Personally, I wouldn't own a 997/987/991 without Sports Chrono. At least on the 997 gen cars, you can add the software easily. Not so on the 991 gen cars. And again, I like the Sprint Booster on top of Sports Chrono / Sports mode for the additional throttle remap.
And back to the Sprint Booster... Where do they claim an 'objective performance gain'? They are very up front about what it does. They don't claim quicker accelration or more horsepower. They don't claim better gas mileage. They don't claim it will solve world hunger or create world peace. They do claim you will enjoy driving your car more with it, or give you the purchase price back.
I've never driven a Sprint Booster on a BMW. Maybe it really sucks. I have driven 996/987/997 cars with Sprint Booster and have absolutely nothing negative to say about it, other than I wish it was cheaper.

If you can get Sport Chrono put on your car for $300, you should absolutely do it.
Are you sure that isn't just the labor price on top of the $900 kit which includes the software license and button?

You are correct, $300 was their labor cost. I already have the software license and button at home.
As for Sprint Booster; their website claims there is a delay in throttle on these cars. That just isn't the case with the 997 with a 6MT. Adding a booster isn't going to reduce the time of the signal to accelerate.
Maybe some of the cars they sell it for that have slush boxes.

Pretty sure if you installed the SB along with an IPD plenum and removed the cats, you'd gain about 100 HP. Better yet, switch your oil to Motul, and you'll gain 105.
At least that's what I thought about doing, and my imaginary butt-dyno swore those numbers were accurate.

It's ironic how $300 for a plug-and-play Sprint Booster is considered overpriced, but $300 for a dealer to install a button (20 minutes) and load some software (another 20 minutes, mostly unattended). is not.
#59
Install the button yourself and see if you can find a shop to charge you a minimum hour charge to just connect their PIWIS and turn everything on. Should only actually take them 15 or 20 minute or so.

hence why why I haven't installed it yet; based on principle ! Lol
if people like the sprint booster more power to them. Just like I say with other mods that change the car in a subjective way.

A while back, I ask in a thread if any performance software companies would offer the 30 days money back then i would be a buyer, well none replied lol.
