how do ecu's and boost controllers work?

how do they work, is it worth it to get/replace either? thanks!

Call me an a-hole but honestly this should be Googled before posted. Sorry, stop trolling.

Explaining how an ECU works would take pages, so buy this book and similar books -

Should help you to understand the basics of how a ECU, sensors, etc works. Then there's computer code which is alot more complex.

Stock ECU is worth retuning (Nistune) or replacing with an aftermarket ECU (depends on your budget) when adding mods like intake, exhaust, etc due to those mods affect how much ignition timing, fuel a engine needs.

With boost controllers, read boost controller manuals, as it explains how they work. Also you have to understand how a wastegate works. That's both internal, external wastegates. More advanced boost controllers (more expensive) can do the basics of most boost controllers + adjust boost level based on rpm, throttle position, gear, drop boost level if car wheelspins, etc.

Boost controller is worth it if want to reach full boost quicker or the opposite, drop boost level (to wastegate spring pressure) or raise boost level, helps to get rid of boost spikes, improves acceleration, reduce wheelspin (more expensive boost controller), etc.

agreed. Generation Y is now fading to generation laZy.

Search first then narrow down your curiousity to a more specific question.
Asking how an ecu and boost controller work and why you need them is like asking how a human body works and why it needs food and water to survive. There is no "quick" answer.
