Ecu
 

I have little knowledge about ECU's and what they do. I do know it's the computer in your car so to speak. How do you reprogram it and whatnot?
yeah i'm a n00b when it comes down to most electrical componets in a car.

it controls basicaly everyhing in your car thats got electricity through it. to reprogram it, you need to take it to someone who knows how to hack a honda program
