Can you activate Sport mode without having SportChrono Package?
Hi everyone,
I'm new here, tried to do a search for this question but didn't seem to find an exact answer, (and got inundated with information).
I recently purchased a 2007 Turbo but the previous owner did not get the Sports Chrono package. I am really just curious if there is a way to activate the mechanics of the Sport button (the overboost) even though the button is missing. I'm kinda working under the assumption that the internals of the car are the same and they just excluded the button/clock, but that you could tell the system/ECU to keep the boost high if you knew how. Just like the programming for the door locks, etc, can be accessed even without the Sport Chrono package, (via the Porsche PIWIS tester).
It would be ideal if it was something as simple as a toggle on 2 terminals somewhere in a diagnostic cluster or something? I did read how reprogramming the ECU can give you comparable performance but this car is still under warranty so I was hoping for a more 'covert' option that could be removed easily.
Anyways, its not like the car is NOT fast enough, just curious about accessing hidden potential.
Thanks for any info.

Sports mode is a program in the ECU. It changes several engine parameters and activates PASM among other things. The button tells the ECU to activate the programming. If you do not have Sports Chrono, you do not have the programming. You can obtain something similar with reprogramming the ECU with a flash, but it will not be "sports" mode.

Softronic (or any ECU flash) can offer similar or better performance than the factory sport mode, but nobody can "activate" sports mode on a non-Sports Chrono car with an ECU flash. It may be semantics, but the differentiation if important.

Sport Mode consists of no hard parts or modules. It is activated through the CAN line of programming. This can be done by a PIWIS with proper code at a dealer or as I said Softronic. This is only to control the Sport Mode feature of throttle response. This will not make your non PASM car have PASM or add a Chrono feature to pop up on your dashboard.

If you dont have PASM electronic ride shocks, it would not do anything. So you are saying if a customer added for example Bilstein PSS10 PASM Coilovers, could he activate this PASM function through the ECU? Good question. I would assume in this case he would need the hard parts (connections for shocks) to work. I do not have that answer.

The sport mode also allows for a bit more wheel spin, angle etc. before kicking in stability right? I dont think any ECU tuner is going to mess with those parameters.
bbywu: Thanks for the answer. Too bad I will not be able to get that little umpf easily.
It is pretty easy to get a little more "umpf". Just send in your ECU for flashing. I sent mine to Todd at EVOMS and I've got "sport mode plus" running all the time without having to push any buttons.

The problem though with Sport Mode on all the time, you lose top end power because of the EGT is greater which then pulls back timing. Here is a dyno sheet. This is just my opinion...

You can add PASM to your car but you will need to have the suspension to go with it (PSS10 or stock Electronic suspension), the control box, wiring + installation... you can buy a nice set of Motons and forget PASM for the same amount of money. But yes it can be done just ask your local dealer.

The Sport Mode adjusts your electronic throttle to give you 100% of your throttle up front as well as more boost initially. Here is a dyno showing the difference. You can see Torque and midrange is greater. The problem though is with Sport Mode on all the time, you lose top end power because of the EGT is greater which then pulls back timing. BTW with Softronic, you do not have to pull your ECU. Softronic is the ONLY company flashing via the OBDII port. This is just my opinion...
What do you mean by 100% throttle up front? It runs like normal until you want the extra power, then it's auto sport mode plus with no push button action (all electronic). It's really great.

Sport mode definitely affects several system, PSM, shock settings, AWD ratio/engagement, Triptonic shifting times (which I have), boost, etc. So a reflash of a certain flavor gets similar/better/worse results, just not the same results...
Given it would be to ineffective to have different hardware builds of the car I was thinking "Sport" could still be accessible, but I guess in the world of software it would be pretty easy to flash the ECU differently depending on the order of the car. I was kinda hoping Porsche didn't bother, thinking if you don't have the toggle to access it you can't use it and only print 1 ECU firmware, that way the software was there sitting dormant.
Since my car has Porsche Pre-Owned Cert on it, I have 4 years left on the warranty so definitely don't want to reflash the ECU.
Though, with that ODB2 implementation, does it backup your base flash so that you could restore the software. On a similar concept could you get the firmware of a person with Sport and flash that to your ECU, (though you would still need to know HOW to trigger it). That would be risky though since their options should be as close to yours as possible to avoid conflicts... all things I would not try, just curious.
Is there an identifier to the ECU firmware, given the general laziness of automotive industries, I still am entertaining the idea that they didn't bother switching firmwares, (though that might be wishful thinking).

You are correct on your statements here. I do not know about other dealers but mine assured me that with the type of tune I have and hardware my warranty will still be in effect, i have 100K bought my car new. I would not worry about sport mode if you get a good tune, there are a few good tuners out there that will get the job done and then some!
