I have a older power vision 2 that was purchased new from Fuel Moto in 2015 that I used on my 2012 Fatboy. Other than buying a new license for the power vision do I also need to upgrade the firmware and software on the unit before using it on my 2018 Softail?
Yes you need to update the firmware so it will read the 2018 ECM and then you will be able to purchase a tune license.
