Not quite right. Keep in mind that navigation equipped cars get a timing (clock) signal from the GPS constellation and that signal is parsed out and to the clock.
Interesting, but you probably would still have to translate it so that the clock from the Macan understands it. Pretty much impossible w/o Porsche disclosing their CAN bus codes to the public
Thanks to everyone on this post I came to realise how useless the 987 chrono clock is so I too decided to change it for a normal clock. Simply used the power, earth and illumination wires from the chrono plug. Works great.
Reading this thread makes me feel fortunate that my 997 GTS was not optioned with SC.
I added the software and button with the OEM SC kit, installed by a P dealer. While many question it's utility on a 6MT car, I really appreciate the revised throttle map and raised PMS activation threshold it provides (at a cost, true, but who really GAS?). I drive, when not in city traffic, in SPORT mode 90% of the time.
I never, ever, look at the wart on my Macan GTS dash, so I share the frustration when driving that one.

I want this!!! That is great work. Now the only question is how? Am good with my hands but just like another you lost me when you started to talk in German..." aldruino etc"
Maybe, and this is a big maybe, it could be useful when lapping if the yoke could be configured to reset the lap with just one pull of the lever. I wonder if anyone has actually sorted a way to actually use the thing for its supposedly intended purpose?

OK, I had been asked before if I want to productize and I didn't want to do it
Here is what I might consider to do:
I could create all the electronics and you would have to do the "final assembly"
Here is what you would get:
the black box from post #1, containing all the electronics loaded with the code, tested and working
a 4 prong connector (to connect wires coming from the CAN bus)
the LCD display that you can also see in post #1, connected to the "black box" with a quick disconnect cable
So this way you don't have to learn how to solder and how to program an Arduino, But I'd leave all the mechanical work (including building your own gauge) to you. What you would have to do:
tap into the CAN bus (it's next to the fuse box in the passenger's footwell)
tap into ground and ACC (same location)
pull these 4 wires (CAN+, CAN-, ACC, GND) to the opening for the wart
take out the wart and disassemble it
create you own new instrument by cannibalizing a VDO (or similar) gauge and installing the LCD display in it (and if you're mechanically inclined your result will look better than what I did)
put it all together and enjoy your new gauge
I haven't priced it yet, but it probably would be in the $200 range
If anyone's interested let me know, but warning: there's still lots of DIY left for you to do. It's not plug & play.
Oh, and one more thing: I only know for sure that it works on 997.2 unless someone let's me try it on a 997.1 I won't know.

@Hatzenbach. Thanks so much for the guidance. Really amazing stuff.
I went with a parts list and the figure it out method. Just need to put it all together now and make it look pretty. I don't have a sport chrono so something custom coming soon.
If you haven't played with this type of stuff before or don't have working knowledge of electronics/coding, trust me, just pay Hatzenbach the $200 or whatever his final cost would be.
Slow moving with the little spare time I have. Although I built a guage, since I don't have sport chrono, I built a little insert for the lower center cubby.
Really skilled project- Impressed. Question to all_ The wires/bus controlled from the indicator lever. Is there and interface to connect a clock if the car has no sport chrono option from the start or is it a complete different harness they put in its a non sport chrono car.
Im without a 997 at the moment but will have one again when the right car turns up. The 911 era ends with the 997: gen 2 for me.

Absolutely no idea. But I don't think anyone would know: In order to look if there's a cable you need a hole in the dashboard and you only have this hole if you have a sport chrono clock. Classic catch-22

Yes, very true. I guess it is NOT there because wires cost money. But have anyone seen if there is a connector or outlet on the wires (BUS) somewhere in the area of the lever or if someone know where the wire from the clock connects into the lever?
He put an SC on his 997, and then played around with the wart. Here's some of the info:
Right now I am in the process of creating custom gauge faces (digitally) to look the way I want. When I am done, I’ll have various screens at the ready (to toggle back and forth it comes with a simple 4 button remote). Meanwhile, here some of the features of the PLX OBDII multi-gauge: Features
Compatible with all OBDII protocols (1996 & newer)
Check and clear Check Engine Lights and codes
Customizable gauge styles, backgrounds & colors

Great thread, at the end I understand "Babygriz" (at the end of the thread) also have played around with the chrono and actually found the plug in from the harness so there must be a connector in some way there to the lever and control the watch from it. Wonder if the software is the same...
I just love he put the drill in the dashboard and went for it. AWSOME! It reminds me when i put side markers on my 964 and put the drill in the front fenders and went for 0,5 inch hole in the sheet. Steady steady, NO slipping No slipping.......
