The following video provides a brief overview of the factory calibration (STK) file. This particular one is from the 2017 Roadmaster, however the components of the tune are the same for 2014 through 2022 except for the Drive By Wire tables, which Polaris expanded in 2019 with their Drive Mode selection.
On the next post, I will start going through each aspect of the tune in greater detail. Once a through understanding of these tables have been gained, we will start the process of tuning the fuel tables.
