So I bought the 1299 slip-on brand new thinking it’s the same for the 959. The exhaust physically fits perfectly but the dealer got an error that the upmap key isn’t compatible with the bike when they tried to install the upmap. Has anyone gotten this to work? I saw someone in another thread say it does work.

Hearsay is that the 1299 Upmap key can be uploaded but only once. Whether it works right on the 959 is another topic.
They're two different engines therefore it's justifiable that the maps are different.
Can't you get the vendor to take back the 1299 kit for a 959 kit?
If not, a Rapidbike unit is your best option.
