What are trim codes for injectors?
What Are Fuel Injector Trim Codes?
- In short, trim codes or trim files are codes that go into an Electronic Control Module (ECM) that determine how long a fuel injector injects fuel into a cylinder for.
- If an injector needs a trim code, it should come with one.
What are trim codes?
Trim codes, or trim files as some may call them, is information that tells your ECM (engine control module) how long the fuel injectors need to stay open. Without proper trim codes, you could run the chance of rough idle, poor fuel economy, and in some cases, even engine damage.
Do you need to code injectors?
Coding is fundamentally the most important aspect of CR injector calibration because new and reconditioned injectors alike need to be re-aligned to deliver the correct quantity of fuel at the right time during the combustion stroke, to meet stringent emissions standards.
How do I find my injector part number?
The location of the part number is dependent on the brand of the injector and the fuel type (petrol/diesel). The majority of diesel injectors are made by Bosch and the part number is usually found on the pin connector unit above the O ring , however on some injectors they will be on the main body.
What is injector calibration?
In a fuel injector calibration phase performed during manufacturing, the method comprises (b) operating a fuel injector at a second predetermined number of engine operating conditions; and determining a function of the nominal value based on measurements of performance of the fuel injector, the function of the nominal …
Should walls be darker than trim?
Painting Trim Darker Than Walls If you want to create a contrasted look or bring focus to your windows or door frames, choosing a trim paint color that is darker than the walls of a room can be an ideal choice. Try a dark hued paint that is several shades darker than your wall paint to create a sense of depth.
How do I know what size injectors I have?
- Injector size = [(350 x 0.6) ÷ 8] ÷ 0.9.
- Injector size = (210 ÷ 8) ÷ 0.9.
- Injector size = 290cc or 29 lb/hr injectors – rounded up to 330 or 310cc.
Where do I find the trim code for my injector?
Some injectors will come with a disc containing the unique trim code file. The disc will go into a computer and the computer will get connected to the ECM. Some programming will run and the injectors serial numbers will be inputted, which tells the ECM all of the injection data. If an injector needs a trim code, it should come with one.
How many injector codes do you need for a C-15?
Just in-framed a C-15 at work (my first cat rebuild). Has anyone ever ran into having brand new re-man injectors right from CAT not having the 12 digit code needed for the trim files.
Do you need a trim code for a Delphi injector?
If an injector needs a trim code, it should come with one. For example, the Delphi injectors from HHP that fit Caterpillar C7 and C13 engines come with their own unique trim codes and the discs to access them. Want the best fuel injector information?
Where does the trim code go on a caterpillar?
Trim codes or trim files are codes that go into an Electronic Control Module (ECM) that determine how long a fuel injector injects fuel into a cylinder for. Trim codes only apply to electronic Caterpillar injectors and some newer electronic Cummins injectors.
