Gen 2 IC upgrade + reprogramming

[dbrom]

I'm interested in buying a 2nd gen IC (higher resolution) for my '13 P85+. I read it has to be reprogrammed or the vehicle won't start. I've asked my local SC for assistance but someone suggested I look for reprogramming assistance here as well. I'm in So Cal.

Hello, was wondering if you had any success with installing a Gen 2 IC in an older Model S. I am looking to install one in my 2012 Model S but am not sure what problems I will encounter. Thanks for any help you can provide.

I took advantage of the $1k price reduction and upgraded to MCU2 this past July; the upgrade includes a new, higher res IC. It feels like a new car.
