Install Unique Trim Code.
For Best Performance. Every Time.
Unique trim code for required injectors must be uploaded to the
engine ECM for proper engine performance.
Delphi C7 , C13 and C15 injectors are supplied with a unique trim code developed during the
remanufacturing process. The trim code is a part of the injector. It is as important as the
o-rings, the nozzle or the plunger and ensures optimal engine performance by compensating
for variations in injector flow and timing.
These injectors should never be installed without installing the trim code. The trim code
is supplied on a CD in the box with the injector and should be uploaded to the ECM using
www.delphitrimcode.com.
Installing these injectors without the trim code can potentially create a number of problems:
• Low power
• Rough idle
• High power
• Emissions issues
