Why Trim Codes Are Important

  • Machine tolerances may cause slight differences between injectors and effect fuel delivery.  Variations in timing and flow may lead to decrease in engine performance.
  • Unique Trim Codes for each injector tailor their performance to the optimum specifications.
  • Delphi Remanufactured injectors are supplied with a unique trim code, located on a USB flash drive, to tailor each injectors output.
  • Using the Delphi Trim Code Software to enter the new unique trim code provided into the engine ECM helps ensure proper engine performance.
