Default JB4 with mods? - 03-27-2019, 02:34 PM

Hi all,

Hope I'm asking in the right place. How does adding mods work with the JB4? Lets say I wanted to add a new after market midpipe, or an M performance exhaust to my m240i...is it all just plug and play or do I need to change parameters on the JB4 through the software to make it all work optimally?

Thanks!
