DW Injectors Combine Precision, Fitment, Data, and Value to Maximize Your Performance Outcome



Most Comprehensive Offering

Fuel Injectors

Fuel injectors are not a one-size-fits-all type of product. The right fuel injector must combine the elements of fitment, coil impedance, flow rate, and tuning data into one injector specific to your engine's needs. This is a lot to ask an injector line up consisting of only a handful of options. DW has the most comprehensive injector offering in the industry so we will ALWAYS have what you are looking for...

Proper Data is a Must

DeatschWerks Data

The right tool, used incorrectly, yields substandard results at best. Fuel injectors follow this same universal law. Proper data is required for proper tuning. All DW injectors are fully characterized in-house via SAE J1832 standards. Injector data is available in General Characterization Summaries and Application Specific formats. Using the data is easy. Often it is cut and paste from the DW excel sheet to the tuning software.


Dynamic Flow Matching

Quality injectors mated to proper calibration data will still perform poorly as a system if the injector set is not properly flow matched. The DW dynamic flow matching process ensures each set works together as a system to fuel your engine properly. Fuel injectors do not operate in a static state so why test them in a static state? In the engine, fuel injectors are a very dynamic component, constantly changing frequencies and pulse widths to precisely deliver the fuel needed. The DW multi-point dynamic flow testing process mimics these conditions by testing at multiple pulse widths within each of the ranges below…Fuel Injectors

  • Low Range(1-2 milliseconds) – Low pulse widths are used during idle, light throttle cruising, and deceleration. However, expensive electronic flow meters are required for accurate testing in this range so few companies actually balance their injectors this low. Low pulse width balancing is crucial for a smooth idle on large injectors.
  • Transitional Range(2-4 milliseconds) – The transitional range covers the pulse widths that typically make up the non-linear range of injectors. Although most DW injectors are linear well into the low pw range, transitional balance is important because many high flow injectors spend a majority of time in this range.
  • Linear Range(4-10+ milliseconds) – The linear range pulse widths are used during medium and high load conditions. Proper balancing in this range allows for advanced timing and increased boost pressure to yield higher and safer peak horsepower.
  • 静态流- Many companies that balance their injectors only test at static flow. In the engine, injectors do not operate at a static state. However, the static rate is still considered the “call-size” of the injector.


Product support is extremely important at DW. Modern fuel systems are a complex arrangement of integrated components that must all be working together to function properly. One out of spec component can cause significant issues for an otherwise properly engineered system. DW provides customer support in various ways…
