Is the fuel injection system still open loop?
It should be noted that changes to incorporate closed-loop operation under certain operating conditions is a recent addition but the system operates virtually the same. In theory Harley’s fuel injection system is still an open-loop system by design.
When did Delphi start using fuel injection on V twins?
You can be sure that it will not be many years before all V-twins have fuel injection as standard equipment. For 2006 HD Dyna model bikes and all 2007> later HD motorcyles, the Delphi fuel injection now operates in closed loop mode with a pair of narrow band O2 sensors.
How does an electronic fuel injection system work?
In its simplest terms, an electronic fuel injection (EFI) system is a computer controlled fuel delivery system. This electronic control unit (ECU) reads various sensors located on the vehicle and makes the determination of how much fuel to allow the engine to have based on this information.
What kind of fuel injection does a Delphi motorcycle use?
For 2006 HD Dyna model bikes and all 2007> later HD motorcyles, the Delphi fuel injection now operates in closed loop mode with a pair of narrow band O2 sensors. The NBO2 sensors control the fuel mixture when idling and cruising.

Are there any misconceptions about fuel injection?
Many mechanics and most riders really don’t have a good idea on how EFI works and how the primary components interact. Misconceptions about EFI abound and the amount of bad information being passed around is high. By the time you have finished this article, you should be thoroughly confused or have a new understanding and appreciation for EFI.
