Ok...here's another question for the tuners. When I totalled my 2013 Roadster it had a PC V and Auto Tuner w/wideband O2 installed. It all...ummm...."fell off"

before the bike got hauled off to the breakers.
Can I install it on my current 2012 Roadster and run with the map that was already on it, letting the Auto Tune fix the mix, or will I have to download something new?
