: I need help on this one, I am doing a project about 300zx TT ECU's. I need to find ALOT of information about how exactly they work. I know how they work, but i need detailed information, of what they do. Does anyone know a site or just know alot of information about 300zx TT ECUs (ECUs in general, the basics and the detailed) that they can share with me? I am going to call Jim Wolf and see what he says about it.
