I ordered it on my RS thinking it was a lap timer? What does it actually do?

It seems porsche uses the RaceLogic data lap timers.

The lapping software with the iPhone app is standard on the 991.2's. But the sport Chrono adds a triggered lap timer receive/transponder setup. The car is wired for the receiver. Think of the old hotlap timers. You need to buy the receiver/transponder, Suncoast has them https://www.suncoastparts.com/produc...APTRIGGER.html.

It does add a manual lap timer that you need to trigger the lap with the steering wheel stalk.

To me it's just cheaper to buy an AIM Solo or similar unit, plus its easier to deal with.

It's a complete waste of money.

Adds the lovely pimple on the dash.

Nah, personally i like the stopwatch / clock look on the dash. Adds a unique element to the interior IMO

This, and that's about it.....

It is a must have option.

I use it when sitting at traffic lights to measure the time it takes to turn Green. I use the cumulative time to measure other traffic lights on my route, then drive alternative longer paths with no traffic lights and arrive to my destinations in less time, while on a longer drive, and what's bad about driving a GT3RS a little longer?

Wish my car DID NOT have it....but I bought used so not much of a choice. Only good thing is my wife likes to ask what time it is all the time...so I just point to the sport chrono...LOL

Thanks guys.. sounds like a waste of money, regret ordering it. Should have put the money towards a real Data logger.

I like it. Leather dash so it's not plastic. And I hit the track a few times a year so no need for all the fancy third-party gadgets. I can just hit the steering wheel stalk when I cross finish line to time each lap and the car's app automatically records the video and data logs. Plus it looks cool on the dash. Otherwise you got this big, open, flat space that's unused.

Hmm, better for a $200,000 car to have a dashboard looking like a bus dashboard?

"less" is more

This has been the same with Sport Chrono since my 997.1 Carrera S. You'd have thought Porsche can add a simple 20hz GPS devise and integrate it to Sport Chrono. A lot of people struggle to get the precsission lap timer app working. McClaren give you a car with cameras and GPS integrated for lap time info and analysis. It really bugs me when we pay pretty big bucks for these cars then they skimp on something so cheap and readily available aftermarket. Why do that to such a loyal customer base?

Exactly, how difficult would it be to have a front facing camera (720s) and gps, they could even “Porsche ridiculous” up charge the cost.
And most would get it regardless.

What data logger did Porsche use for testing and Ring lap times ? I am guessing Racelogic?
