Fuel injectors
efi2000 has a vehicle library of common engines and parts you can select from. Picking a part fills your project with verified data, so you can configure it quickly, and that data is used to improve your tune.
Injector flow and dead time turn the fuel the engine needs into pulse widths. efi2000 uses them to calculate required fuel, set injector constants and flag injectors that will run out of duty cycle.
36 fuel injectors
