Is it worth updating all the car modules?

Hi guys thanks for reading,

I have recently replaced an amp and flashed it successfully in my f20120dX and I'm comfortable with doing so, I also have a suitable power supply that can manage 50+ amps for prolonged flashes. While flashing the amp I can see all the modules are out of date with an original 2014 istep shipment version

So my question is - is it worth updating all of these modules? Will the car have anything new or noticeable about it and/or where can you find out the information of what's new in the update, a changelog of sorts if it exists?

Thanks in advance for your time and suggestions

I see no reason to do so. If it makes you feel better then just do it.

on the contrary, some updates prevent access to coding so I would say, since it works well: we don't touch anything and we take advantage of it!

BMW says all ECU needs to be on same Level, so when one Ecu is replaced and needs a flash.. all ECU were flashed to the newest Software
