Hey guys, I just purchased my dream 991 Carrera S and it's coming to San Diego this weekend. It's just missing the sports chrono package, and after going down the rabbit hole of others that have tried retrofitting this for 981's (minus the active engine mounts), I think I'm going to be the guinea pig for trying this on the 991.

Does anyone have a recommendation for a tuner/mechanic in Southern California with PIWIS 2/3 Engineering access? That will be the tricky part of this project, since sourcing and transplanting the physical clock and sport plus button seem straight forward.

Here are some threads for context to what im trying to do. Major props to @Visual for being the pioneer on trying this.

I know that Vollig Autowerks (9393 Trade place, san diego) has a piwis. No idea though if this is a project they want to be involved with. You can call there and ask for Adam.

Please keep us updated on your progress! Very interested in doing the same to my 2015 Carrera S with manual transmission.

@mwjackson92 Please keep us updated.
I purchased a chrono clock as well to retrofit in my 991.2, I know from previous thread where to wire back to the unit just to get clock working.
Interested to know if you are able to activate chrono option on PCM4 via PIWIS. I am ordering a PIWIS so I can get it done in few months as car is in storage now.

This is an YouTube video for install and wiring of the clock:https://m.youtube.com/watch?v=tjiQIruEEBA


Thanks,

I want to do the chrono clock additon as well for a 991.2, but nowhere kind I find if the clock has to be a 991 clock or if Caymen and Boxter clocks as finding used ones in good conditon is a challenge.
Does anyone know the answer?
TIA,
KW

Hey Cedric, I wish I had better news for you. I researched this high and low, and my PCA friend was a master tech with Porsche and has a PIWIS 3. We were able to install the clock and activate the G meter page, but couldn’t activate Sport Plus or the chrono timer. The clock functions as a clock just fine, synced to your PCM time.

Hey KW,I have a 991.1 and was successful using a 2011 Panamera clock. The Boxster, cayman, and Panamera chrono clocks are often 1/2th the price but function and look exactly the same. The part number will be slightly different, but the harness plug in the back is the same.

Clock has been working well for me, sync time with PCM. G meter was already on for me as I have a GT3. I don’t need Sport Plus as I have a manual but would be interested if I can get chono timer. In the meantime, my phone with external GPS is doing the job on track days.

Thanks for your feedback

Reviving this thread. Cool to see folks retrofit the clock, housing and wiring to power it on.

For GT3 owners that have a PDK, anyone get the timer to work?

They are out of business.

Working here is Gary, one of the best tech I have ever met. He had worked on my ex-991.1 Carrera S and now my 991.2 Carrera GTS. Gary worked at Vollig until it went under about a year ago.

When you talk to Chris, tell him Martin referred you.
