I'm a pure noobie when it comes to hooking up cars so please take it easy. I've heard if you wanna mod up ur car a good thing to do is to get an adjustable FMU. I have absolutely no idea what that is. Can someone explain to me what it is, what it does, and/or where I can get one for my 1997 Maxima SE Manual?

 

an fmu is a fuel management utility. you shouldn't need it unless you have some pretty major mods such as nos or supercharger or turbo.
