Default 2019 X3 M40i 1,000% Newbie with jb4. - 07-12-2020, 01:17 PM

I have a 2019 X3 M40i and recently installed the JB4. The only mod I have is a K&N air filter. I keep the can flap open and I run 93 octane. I was told to just put it on map 3 and have fun, and that I have! However I’m seeing a lot people talking about making tuning adjustments…. I see on the JB4 Mobile app under settings there is a advanced settings tab that allows you to access “User adjustment settings” and “WMI”. Should I be making adjustments to any of these or just leave them alone?

Log looks clean to me, no adjustment needed.

WMI is for water/meth kits, user adjustment options are for when changes are needed or you want to reduce boost in lower gears, etc.
