I think MFI is normally "Multiport Fuel Injection", not "Mechanical Fuel Injection". Fuel injection which is not multiport is called TBI or "Throttle Body Injection". This was used on lots of American engines in the late 1980's. The throttle body was mounted where the carburetor would normally go. It used one or two injectors. MFI is supposed to be better than TBI. The best kind of MFI is sometimes called SFI or Sequential Fuel Injection. SFI systems operate the fuel injectors sequentially. Regular MFI operates the injectors all at the same time.
