Remote pneumatic aneroid fuel controller devices and methods

A method of controlling tuning of an engine having an aneroid fuel control (AFC) fuel injection system, the method comprising:

• providing a vehicle having an engine, a passenger compartment, and a pneumatic control device positioned in the passenger compartment, the engine having an aneroid fuel control (AFC) with an air fitting, the pneumatic control device comprising a pneumatic pressure regulator and a pneumatic flow control valve;
• controlling flow of pressurized air to the pneumatic control device;
• converting the pressurized air to an air signal by passing the air through the pneumatic pressure regulator and the pneumatic flow control valve;
• controlling flow of the air signal from the pneumatic control device to the aneroid fuel control with the air fitting, thereby adjusting a tuning setting of the engine.

A vehicle having a tunable pneumatic fuel injection control system for a diesel engine, the vehicle comprising:

• an engine positioned on the vehicle, the engine having an air intake plenum;
• a boost system connected to the air intake plenum of the engine;
• an aneroid fuel control (AFC) controller connected to a throttle of the engine, the AFC comprising an adjustable air fitting;
• a passenger compartment positioned on the vehicle;
• a pneumatic control device positioned in the passenger compartment, the pneumatic control device having a pneumatic pressure regulator and a pneumatic flow control valve, the pneumatic pressure regulator and the pneumatic flow control valve being flowably connected to each other, the pneumatic pressure regulator regulating a total air pressure output by the pneumatic control device, the pneumatic flow control valve controlling a volume of total air exiting the pneumatic control device;
• a first tube connecting air flow from the turbo system to the pneumatic control device in the passenger compartment;
• a second tube connecting air flow from the pneumatic control device to the air fitting.
