Newbie question: what is an ecu tune
 

hi all. sorry if this has been asked before or is a stupid question. ive just started to learn about car modding etc and was wondering, what is an ecu tune? ive seen some around for our cars such as the visconti and fa20 tune but i dont really know they are exactly. And how do i install them, so to speak? Can anyone give some insight? :) thanks!
Pls dont troll or flame :/ im really legitimately new to this. thanks!

The tuners can adjust fuel, ignition timing, cam angles etc. all electronically through the Ecutek tuning software to make more power and make the motor more efficient.
