Porsche 987.1 Sport Mode Software


Recommended Posts

Hello! I have a 2007 Cayman S but it does not have the Sports button on the dashboard. 
I want more throttle response and sports feel from the car. What's the best update/upgrade I can do? Any advise. 

I can see Sun Coast Parts in the USA sells this. Do you know if anyone in the UK does this fitting?

Thanks you!

Any dealers can retrofit it. (but they won't add the clock on the dashboard thought - this can still be done but it's another £1K or more) 

 

Cheaper and BETTER option is the Sprint Booster.  Works amazingly, you have 18 settings and it's only £189.

 

No, it's not better.  It sacrifices control for false throttle response by commanding significantly more throttle than input.  It does achieve the desired effect, but at the cost of control.  Yes, it's cheaper, but so is training your foot to press the throttle more which is exactly the same behaviour simply achieved without the SB.

 

The OEM option creates a linear response between commanded throttle and actual throttle.  A remap will also achieve the same behaviour: 30% commanded throttle results in 30% TPS/actual throttle.

 

Input throttle - amount of deflection on the peddle/APS

Commanded throttle - ECU receiving the APS input

Actual throttle - the amount of TPS-based movement created by the DBW system

 

SB spoofs more input throttle which increases commanded throttle.  Chrono/remap creates a more linear response between commanded throttle and actual throttle with no modifications to input throttle.

 

@Shenshah, there's a few threads that have done the Sport Vs Sprint Booster discussion to death already.

18 settings. Read that again. You can have  a 1:1 ration (SB input - actual throttle) or anything below 100% ratio.

 

 

For £189 it's definitely BETTER. Plus you get valet mode and you can use a pin code to limit/lock inputs. 

No need to visit any dealer, takes 5 minutes to install. 

 

But I guess Aaron at £700 for a on/off switch you are right, like always 👍

If you have DSG it sharpens up the gearbox performance (faster shifts etc) and also PASM if you have that.

 

If you have a standard manual car, it also allows more revs and alters the rev limiter behaviour which a pedal box mod alone doesn't do.

In a comparison of raw functionality, it's certainly not better.  When you bring the cost into the equation, I certainly agree there's value in an SB.  Never said there wasn't...  However, if you can't grasp that training one's self to press the pedal further is the same behaviour, I fear the point may never make it across.

 

A remap would be significantly better value than both options.  Same behaviour as chrono minus the toggle but with improvements throughout all engine characteristics not just throttle response. Also cheaper than the retrofit. Sounds like the real winner to me, personally.

 

I laid out the other possibility for the OP (remap) and the facts around the different behaviours of the solutions offered irrespective of cost.

 

We can agree to disagree about the merits of the SB but I prefer to give someone all of the options before shoving my recommendation forward blindly ignoring other possibilities.  This way, the OP can make their own decision based on the options available, their pros/cons, and the cost for each respective one.

I really appreciate your (and others) detailed technical explanation and giving me all the possible options out there :D It's really great to hear the pro's and con's of different methods and the price implication it has! This has opened up another galaxy in my brain to research and figure out what would suit my driving style. I've a feeling remap would be more suitable for me as I get lil tired and sloppy with the pedals on a long drive and I got a feeling SD would be dangerous for me! As they say, Speed thrills but kills ;)

I see!  If you're sloppy with pedals on long journeys, I would recommend the chrono retrofit as you can turn the car back into its timid self with the button and only utilise sport when you fancy a more engaging drive.  With the SB, you have to stop and play about with it and, in comparison with a remap, there would be no turning it off.  Aftermarket remaps for 987s don't support map switching like some other aftermarket remaps, unfortunately.

 

Also, like Andy mentioned, if you have PDK or PASM, it changes the game again.  PDK in sport mode is next level to stock.  You can flash the PDK ECU with a more aggressive map but this doesn't give the toggle on/off functionality of chrono just like an engine ECU remap.

I've never had a Cayman with Sports Chrono so cannot add to the for/against debate but just to clarify that the SB function can be turned off via the dashboard button (if you decide to install it).

The OEM Sport button raises the PSM threshold as well so its not so intrusive and also gives a harder rev limiter
