So many people who have zero clue commenting here.
You are not getting any upmap for the v4 for $300. You are not getting ANY map for any dollar amount.
The original map is registered to the bikes Vin when installed by the dealership and is not eligible for resale or transfer. You bought an exhaust only, no mapping will get done unless somehow Ducati "generously" sells you a new map for probably $1,500 or so. There is no aftermarket solution to date that I'm aware of.
Tip- don't buy used V4 exhausts and expect a fueling solution.
Ducati did away with maps being transferable. Do yourself a favor and buy a bike from a brand that doesn't ......... it's customers at every turn. The V4 map is downloaded by the installing dealer. I'm not sure how Ducati gets away with this given consumer laws in the us designed to specifically address despicable practices like this. This is a clear disincentive to buying a used system so they can get more of you suckers to spend $5,000 on some bent metal pipes new.
