How Can I Change Service Intervals?

[Edi-EZTuning]

This is for my 2016 M235i xDrive.  I've read some posts where people have changed the service intervals, but I can't figure out exactly what I need to change in e-sys.  I'm mainly wanting to change the time between oil changes down to 5k miles.  Does anyone know how I can do this?

try using ISTA , i think interval minimum at 8k for 12 month
