ok.. i have a 00 civic dx, sohc d15y7. i'm wondering if i can get an ecu chip for it and where i could get it? and if i do get one, do i need to do anything or is it just 'plug and play'? it changes the fuel and timing maps, rev limiter, and can remove the speed limiter -- am i correct? is there more to it? i'm still new to the whole "car" knowledge thing and would like any help i can get. i believe it's an OBD2.. someone also tell me what that is -- a newer generation from OBD0/OBD1? and also where can i locate it in my car..

sorry if i ask too many questions any information will do, i enjoy learning.

thanks in advance,
