It is possible to D.I.Y tune ecu??

We buy the adapter and connect it to computer usb then we install software in the computer then we tune it ourself??Anyone done this before???

yeah many have tuned themself, but u got to understand, u have to face the fact that practise makes perfect , if u tune urself without experience and knowledge , it will blow

things that i know tht u need to know

base map , ignition timing limits of your engine , engine knock reading, wideband sensor and logging , must know how to read lambda and afr , wht afr suitable for turbo , wht afr suitable to acceleration , wht afr suitable for n/a , experience of hearing engine sound to know if there are any problem or faulty , i would say its more to experience , i put my hands up in the sky and surrender , i cant tune cars :D
