According to them, PIWIS would be required. They'd provide an activation code, and that module they provide sounds like it'll force the code through instead of the roadblock we're all having when we buy a code separately and are unable to get it to work.

 

According to AutoSvs you have to code some custom field with PIWIS, but apart from that it's Plug & Play.

My guess is they've found some unused data field, and have encrypted their device somehow to ensure someone doesn't just copy their code and duplicate it I bet it's something like an Arduino board with Dual-channel LIN interface..

I asked for installation instructions but was told I can't get a copy without buying. That's a bit suspicious.

I've tried asking for a group buy, but they will only shave a small amount off... I have also asked for special pricing in combination with publishing a detailed review. No luck whatsoever...

I have some photos of the unit which takes power from the push button unit, and piggybacks its LINBus. On the far side of the BKE you have to cut the LINBus line to the vehicle and put this unit in the middle. That's why I think they're stripping the 'Sport' code from the BKE output when SP+ is selected, and replacing it with 'Sport Plus'

I told them when nobody else in the US has experience with this unit, $1,300 is too much risk for me... the answer was "understood".

 

I asked for it last year to give a copy to my mechanic, here you go. Probably not as detailed as you're hoping since you seem a bit more technically nuanced than me!

I feel a little wary that they're not interested in letting you do a detailed review. Hell i'd give you one for free, if you did a review and said this is a good product, they could easily sell 100+ units from all the people with sport chrono envy across Rennlist, Facebook, and the PCA groups.

 

On my 2014 981 Cayman S with a 1/14 build date the BKE air con unit is A2.3 with HW version 406 and SW version 1800. And as mentioned above would not activate after entering the hacked activation code with PIWIS2.

To clarify the price on the AutoSvs site is currently listed as $1499 plus $70 shipping. Count me in if someone can put together a group buy at a reasonable price.

Let us know how this looks with some pics if possible once you get it installed. I've surprised you can't control the light intensity with the rest of the dash since it's tied into the communication bus on the car.

 

As far as my research goes with PIWIS, I've gone and looked through the piwis folders, found the MCR (Coding rules), and found the firmware as well. I managed to acquire the bin files which contained 4 files. The flash driver, app 1, app 2, and data blocks. With that said, I can't make sense of the bin files. They don't look uncompressed, or encrypted like the ECUs, and they also have a part number in the bin files (which leads me to believe they're as raw as they get). I haven't ripped apart the AC unit yet to figure out what it's running on but if anyone has any info/advice that would be awesome.

I'm also a bit hesistant to use autosvs method as there is this method here that exist: There's also another video, and both videos show both codes. With this method I don't see any retrofits with the yellow module. I've contacted clsautostyling and I'll update if there's anything there. In jest, there's only 16^8 combinations. Computers now can crack that!

 

I've also reached out to the company that made that video but haven't gotten a response. That solution would be great.

 

Count me in on group buy AutoSvs site

 

A 991.1 S would already have Sport Chrono, no?

 

I have 991s with no SC.

 

I bought the sc aftermarket off of ebay. The material looks OK color looks to be the same looks and fits oem for me. The gauge light is a bit bright but it's not that bad.. I haggled with seller to get a lower price. The wire kit provided looks oem no wires need be cut. The hardest part was trying to remove the dash plate to put the Chrono in.

 

It is an option, so not necessarily.

 

Hate to complicate this more anyone ever changed this sports Chrono to a digital one and somehow project ob2 data on it. Looking to see if I can make it more useful

 

I definately want to add the clock even if it's just for the look and time function and hopefully some other function if I can get coding worked out. I'm just not sure if I should go with amazon/ebay new Chinese solution or OEM used unit from 911 or other porsche. I read about the non OEM unit being too bright so I assume the OEM version gets brightness level from cars Canbus. If I decide to buy an OEM unit not sure which others would work like from 982, Macan or Cayenne.

 

Oem will prob set u back more than knockoff. I see if I cam video or take Pic of mine in dark mine is not oem. I don't think it's that bright but maybe it is for some
