Features
Take a look at the advantages and features of HGT PFI
1. Better performance though accurate fuel management and atomization, nearly 10% more peak horsepower as measured on the dyno. 2. Increased bottom end torque, due to fuel being injected on demand rather than needing air speed to draw it into the engine. 3. Larger throttles bodies, intake manifolds and reed blocks can be used to increase air flow since the diameter does not affect fuel flow or atomization. 4. HGT fuel Injection systems contain 192 load based fuel trimming cells vs. 3 carbureted circuits, providing instant throttle response at any rpm or load. 5. Load based ignition timing instead of fixed or linear. 6. HGT PFI engines can literally run upside down with no variation in power or fuel mixture due to vibration or g-forces. 7. Immediate restart if laid down or flipped. No way to flood the engine even when transporting. 8. Nothing to disassemble or remove to change fuel calibrations. All changes can be performed via RS232 cable or optional wireless module. 9. Different calibrations will rarely be required, as compared to carburetor jet changes, because the HGT PFI system utilizes a coolant sensor, air intake sensor and barometric pressure sensor, so fuel trim self adjusts for changing barometric and ambient conditions including under racing conditions.
10. Easy starting at any temperature. No manual choking required. 11. Lubrication can be accomplished via pre-mix, mechanical injection or ECU controlled solenoid injection. 12. Optional wireless interface allows all data to be recorded trackside for live viewing or later playback. 13. Optional O2 sensor can be installed and data logged to facilitate tuning then removed for open loop operation.
Some of the Emissions Based advantages of the HGT FI system include;
1 Closed fuel system, no open evaporative venting or dangerous vapors. 2. Better fuel economy through better atomization 3. Lower emission through better fuel and ignition management 4. Closed loop and catalyst systems are available 5. Less fuel is consumed during deceleration via decell fuel enleanment and decell fuel cut-off calibrations if an external oil pump is used. 6. Self diagnostics with included MIL (Malfunction Indicator Lamp)
