Does anyone know if Ludicrous Mode can be added/enabled post production or aftermarket if desired in the future? Not sure at this point if there is additional hardware involved or just software. I did see some mention of specialized fuse, inferring a HW change/adder. It isn't clear however whether or not the HW comes standard and is just enabled via SW when ordering/configuring the option.

Not sure anyone KNOWS, but I'm assuming yes since someone took a pic of a non Ludicrous pack and it was the same as a car with Ludicrous.

I have a memory of Elon Musk saying that one could upgrade (after-purchase) to Ludicrous mode. I think he was referring to current Model-S owners and it required a trip to the service station because it was more than simply a software upgrade. They had to upgrade some of the hardware too, but it wasn't difficult to do.

There has been some rumours in other threads that Tesla may decide to install the Ludicrous hardware in all new models (maybe only Performance models) and if that is the case, then it would simply be a software update to activate the feature for all models built after the switch-over date.

All 90 kWh packs seems to have the necessary hardware as AO points out. So it would simply be a matter of a firmware update.

Along with my previous memory, I recall Elon saying that it wasn't simply about the battery pack either (e.g. 90 kWh) and as mentioned earlier there is a new smart fuse and perhaps some other upgraded equipment required. I can certainly see Tesla's logic in having this upgraded equipment in all new models (for simplicity) and turn on the feature remotely when customers pay for it.

Ludicrous also included a contactor made of inconel.

The upgrades for P85D's was only going to be offered for 6 months though.

Has anyone actually done the conversion? When I asked soon after it was announced the service center didn't know when they'd be ready to do these upgrades. And yes, this was supposed to be time limited and for "only" $5000.

No idea. I haven't been following as I don't have an S. I wouldn't be surprised to hear that none had though.

Consider this: Roadster owners were notified of a battery upgrade late last year (I think), and are only now able to finally get it.

I wouldn't be surprised if current Model-S owners would have wait until early 2016.

Well seems plausible then. Thanks for the inputs all. I will inquire when my config number is up and report back what I learn. I will likely opt out of Luda upon config, but would be nice to know if it can be added down the road ..maybe even through a hack ;)

It is entirely possible that all new performance vehicles delivered after October will have the upgraded hardware already installed. If that is the case, then it's true that it can be done via a software upgrade. Just like some of the early battery packs had higher capacity, but were limited via software until someone paid the upgrade fee.
