I think Sport Chrono consists of the clock on the dash, the control buttons mounted on the steering wheel (see pic), and then of course the software that makes it work.
I've no need for the clock on the dash, but I'd like the control buttons and the software.
I'm guessing the control buttons could be added if the stock wiring harness happens to include the necessary wires, otherwise not. Or maybe replace steering wheel with one that includes the buttons?
I don't anticipate the dash clock does anything much and that the software is located somewhere else.
So could sport chrono be added to my dream car by adding the buttons and doing a software update?
I wouldn't mind adding the clock as well, just thinking it isn't necessary and would probably be more of a challenging mod.

It is a complete SC system except without the dynamic engine mounts. It is my understanding that the hacked purchased activation code can be installed with PIWIS 2 or PIWIS3 on a 981 or 991.1 with PCM 3.1 but Porsche closed the door on entering a hacked activation code on a 991.2 or 718 with a PCM 4.

Do you know if you get an error in the dashboard for not having dynamic mounts on the engine? I wonder if there are sensors that detect if Sport Chrono is active, Dynamic engine mounts must be "detected" by the sensors.

I am looking fo someone in central Ohio (hint,hint) with PIWIS2 or 3 to activate my hacked SC activation code. I may have to buy PIWIS if I can’t find it. According to Visual in his 981 forum post “981 sport chrono retrofit part 2: software side” he has a fully functional SC package including lap timers, g-force display, launch control and relaxed nanny’s, but no dynamic engine mounts. He did not mention any issues with dashboard warnings.

after installing the sport Chrono activator, go to PIWIS2 or PIWIS3 tester menu, air-con => drive => function enable => input sport Chrono activation code from us.
