FiTech EFI System??

Early Bosch injectors with protruding pintle are, annular injectors dispensing fuel in the shape of a ring. Nothing new about that, Both the 1969 VW T3 and Porsche 914 used annular injectors.

Port injection gets around wet fuel distribution issues. OEM EFI systems retried TBI in the 90's in favor of port injection. The simplicity of installation from carb conversion is only advantage I see.

The system has fairly crude tuning capabilities based on my experience. A 3 x 3 matrix for ignition timing would be similar to a standard mechanical advance distributor. For optimal tuning more points are needed. Fuel tuning is also crude in comparison to other systems.
