Hello everyone, I am getting ready to install my ms3pro pnp ecu I have read and read on here about how to hook up my wide band but unfortunately I am still not understanding ( completely new to MS systems) I have everything for my turbo kit hooked up in my car besides this and my injectors. Can someone please I guess dumb down the process of how to get my afr hooked up to my megasquirt?
