EFI, the only problem that you will encounter with EFI engines are the expensive sensors that gives life to the engine other than the ECU.

electrical system of the whole EFI thing will bother you but the concept of air and fuel are almost the same, the difference when it comes to fueling is that with the use of fuel rails, fuel are sent unto the cylinders on its firing order... unlike in CARB all cylinders are given fuel at the same time... making it less efficient.

both systems have proz and conz...
