A fuel supply system includes one fuel supply and diagnostic module that is used to control various fuel supply system components. The fuel supply and diagnostics module includes a fuel system control unit that operates separately from an engine control unit. The engine control unit and fuel system control unit are electrically connected together via a two-wire connection. The fuel supply and diagnostics module includes a fuel pump with controls and diagnostics generated by the fuel system control unit. The fuel supply and diagnostics module also includes a fuel level sensor and leak detection apparatus that also have controls and diagnostic generated by the fuel system control unit. The fuel supply and diagnostics module is easily installed into a fuel tank as a single unit.

Fuel supply and diagnostics module

An engine management system monitors driving habits of a vehicle operator over time to generate a driver profile. The driver profile is used to adjust available engine power to more closely match the driver's habits. A predetermined nominal engine power versus vehicle speed range is established for an engine. A system controller monitors and compares the driver power requests to the nominal engine power versus vehicle speed range over time to determine the driver profile. The system controller also monitors current vehicle speed to determine whether the vehicle is operating at a low or high vehicle speed. The controller determines low and high speed engine power correction factors based on this driver profile. The appropriate correction factor is applied to modify the available engine power resulting in an engine power output that more closely matches an operator's driving tendencies.
