FI = fuel injection.

Your engine might have the letters "PGM-FI" on it. This means "Programmed Fuel Injection." Honda invented a fully programmable fuel injection computer. Because the characteristics of the engine - number of cylinders, displacement, horsepower, etc. - are all controlled by software, this one box will work on any fuel injected Honda engine from motorcycles to Indy cars.
