I'm trying to upgrade my early 2013 model s60 to a p85. The reason I'm doing this instead of buying a used p85 is because my 60 is my first car and I don't want to get rid of it. This is a crazy idea I'm cooking up in my head so bear with me here. I have been trying to learn how to reconfigure my car to fit an 85 kwh pack and also swap out drive unit for performance. I'm curious if I buy a used MCU and IC out of a wrecked p85 or off eBay if I could fit fit like to like pack and like performance drive unit into the old shell of my 60 with new mcu, software redeploy and have everything work. I know its a stretch but my service center won't do pack upgrades and I have access to a lift and any tool you could think of. This idea sounded a lot better in my head but I just want thoughts to see what you guys think of this idea.
